The CARE process includes the development of: C-bus, LON-bus, and BACnet networks Schematics (does not apply to Excel Web controller and ELink controller) Control strategies Switching logics Point attributes Point mapping files (optional) Time programs Job documentation Supported Controllers and Devices 3 Excel 10 / 50 / 80 / 100 / 500 / 600 / 800 Excel Smart Controller Excel Web Controller Excel Link (XLink) Controller Excel OLink/OPS Controller Excel IRC Excel ELink Standard I/O Modules Panel I/O Modules Distributed I/O Modules Smart I/O Modules M7410G Linear Valve Actuator with LON capabilities and other Honeywell LON devices 3rd party LON devices 3rd party BACnet devices Excel 10 Applications Excel 10 applications use an Excel 10 Zone Manager Controller (ELink Controller) as the interface between the EXCEL 5000 C-bus and an E-bus with Excel 10 Controllers. In addition to providing point mapping between the C-bus and the E-bus, the Excel 10 Zone Manager Controller has the functionality of an Excel 100, except that it has no physical points. Excel 10 applications cover the Q7750A1xxx (1000-series) devices used with VAV 1 (Standard VAV) applications and the 2000-series including the Q7752A2xxx Zone Manager and its corresponding controllers such as VAV 2 and FCU. CARE 8.02.00 can only be applied to the engineering of 2000-series applications. For these the process is partly done in CARE and completed within the E-Vision software tool. The complete process is described in the Excel E-Vision User Guide 74-2588. The CARE steps are described in the Excel 10 Applications section in this User Guide. Excel Link (XLink) Controller Excel Link applications enable the connection of C-NAP bus controllers to an EXCEL 5000 C-bus. C-NAP bus controllers include Excel MicroCel, Excel MacroCel, Excel W7620, and Excel W7600. The CARE process for Excel Link applications is similar to that for the Excel 500/800 controller. There are special considerations as well as additional software requirements for Excel Link applications. Excel OLink/OPS Controller The Excel OLink controller and its successor the Excel OPS (Open Point Server) controller can be engineered in CARE in the same way as a standard Excel 500/800 controller. External bus system information such as from M-bus will be integrated by simple point mapping between subsystem points and CARE datapoints. 4 See Also System Requirements CARE Concepts ******************************************* PART 3 ******************************************* Applicable Literature Form No. Title 74-3556 (US) Excel Live CARE User Guide EN2B-0183 (Europe) Instructions for using Live CARE software to access controller files on-line and simulate operation 74-5577 (US) Excel CARE Control Icons User Guide EN2B-0184 (Europe) Descriptions and application examples of control icons used in the CARE control strategy EN2B-162 RACL Editor User Guide Graphical Editor for creation of strategy logic programs for Excel 500/800 controllers. 74-3594 (US) ASPECD Editor User Guide EN2B-185 (Europe) Provides functions to modify the user interface for Excel Operator Terminals.

A controller can be any EXCEL 5000 controller. Plants are specified by their type such as Air conditioning, Chilled water and Hot water. Physical Control System A plant is a controlled mechanical system. For example, a plant can be an air handler, boiler, chiller, or MicroCel Variable Air Volume (VAV) system which is composed for example, of boilers, heaters, pumps, sensors, and other devices. Depending on the technical function, each device has its inputs, respectively its outputs. The controller and the device are connected via their inputs/outputs. Depending on the used bus system, the devices are connected physically (C-Bus) or logically (LON-Bus, or BACnet-bus) to the controller. The plant is controlled by the application program (control strategy, switching logic, time program) running in the controller. For example, if the sensor gives a changed temperature value, the actuator drives the valve to the appropriate position to compensate the temperature deviation. CARE Control System Model The physical HVAC control system is realized in CARE by a "Controller - Datapoint - Plant schematic" model. 6 Controller The controller is provided by CARE with its controller specific features such as controller memory and datapoint capacity. Plant Schematic The physical plant is represented by a schematic (not applicable to Excel Web controller and ELink controller), that shows the equipment in the plant and how it is arranged. Datapoints At the bottom of the schematic (CARE XL-5000 only), arrow heads represent the inputs/outputs of the equipment as datapoints. They are color-coded, directional (down is input; up is output), and marked with special symbols for additional information: Color Direction within triangle Datapoint Type Green downward Digital input or totalizer Red downward Analog input Blue upward Digital output Violet upward Analog output Light blue upward Flex point Alternatively a plant schematic can be drawn without the component symbols and just displaying the datapoints as arrows. CARE distinguishes between physical or hardware points which are related to physical inputs or outputs and software or pseudopoints. Software points can be created for processing calculation results of software programs. 7 Datapoints are specified by certain properties, such as point type (analog input, digital output etc.), user address (OaTemp=outside air temperature) etc. Datapoints can be identified within the EXCEL 5000 system by their unique user address. To control the equipment, a control strategy, a switching logic and/or a time program is added to the plant schematic (see also CARE Main Applications section). For the control process through the application program in the controller, the datapoints represent links to provide data exchange between the controller and the plant. Data exchange through datapoints will be performed according to the attached logic functions. Project All relevant information of controllers and their attached plants are saved in a project. Example of a project with four plants and three controllers: In addition, general information such as reference number, client name, and order number are part of the project. Bustypes The controller and plant devices are attached to certain communications media (bus) and communicate with one another using a common communication protocol. CARE supports the proprietary Honeywell C-bus (local LON-bus), the open LON-bus (LonWorks), BACnet-bus and 3rd party bus systems such as Meter bus. Network Architecture In addition to the specified bus type, the physical arrangement of the devices attached to the bus can be represented as network architecture in CARE. A project can cover multiple of different buses building up a network, for example, a network can include the C-Bus and the LON-Bus. 8 CARE Main Applications CARE provides four main applications to create downloadable control programs: - Plant Schematics (CARE XL-5000 only) - Control Strategy - Switching Logic - Time Programs Plant Schematic The physical plant is represented by a schematic that show the equipment in the plant and how it is arranged (CARE XL-5000 only). Control Strategy After the plant schematic has been created, a control strategy may be created that provides the controller with the intelligence to handle the system. Control strategy defines loops for decisions based on conditions, mathematical 9 calculations, and/or time-of-day schedules. Control can depend on analog values, digital values, or both. CARE provides standard control algorithms such as Proportional-Integral-Derivative (PID), minimum value, maximum value, averaging, and sequencing. Switching Logic In addition to adding a control strategy, a switching logic can be added to a schematic for digital control such as switch status. Switching logic is based on logic tables that set up logical ORs, logical ANDs, and exclusive ORs. For example, switching logic can be defined to have the return fan start after a programmed delay from the time that the supply fan was started. Time Programs Time programs can be set up that control equipment on/off times to coincide with occupancy. Daily schedules (for example, weekdays, weekends, holidays) will be defined and assigned to weekly schedules. Connecting Inputs/Outputs Depending on the used hardware and bus type, CARE provides 2 methods to connect inputs/outputs between plant and controller. Terminal Assignment (Panel Bus) In case of a physical connections between controller and devices on the panel bus, the controller has panel I/o modules and/or distributed I/O modules. Then, the device inputs/outputs, respectively the corresponding datapoints will be automatically assigned to the controller terminals. The connections can graphically be viewed and re-arranged on the terminal assignment pane. 10 Binding (Open LON-bus) In case of a logical connection between a LON controller and other (3rd party) LON devices on an Open LON-bus, the controller uses neither IP nor distributed I/O modules. Instead, the device inputs/outputs, respectively the corresponding datapoints are boardless. Then, connections will be made by dragging & dropping boardless controller points to LON device datapoints which are called network variables (NVs). The process of connecting LON devices to each other is called Binding. Application Download into Controller After a plant has been completed by editing the main applications such as schematic, control strategy, switching logic, etc. the application files will be translated into a suitable controller format. Then the file will be downloaded and the controller test operation can be started. See Also CARE Features CARE Concepts ******************************************* PART 6 ******************************************* CARE Environment When you start CARE, you can see three distinct panes of the CARE environment. 11 This pane contains the Network Tree and the Control Functions tree. This pane displays the properties and information of the item selected in the logical plant tree, respectively in the network tree. This pane contains the Logical Plant Tree. In the CARE XL-Web environment, the left bottom pane further can be split. So a fourth pane will be displayed. The left bottom pane includes two trees, the network tree and the control functions tree. When starting CARE XL-Web, the control functions tree is not visible. To view the control functions tree, point the cursor on the bottom border till the pointer?s image changes to a split pointer. Move the split bar upwards. The control functions tree will be visible in the fourth pane. 12 Logical Plant Tree The logical plant tree allows to maintain an overall view regarding the logic structure of the project. This helps you to manage and organize the logical components (controllers, plants, datapoints, schedules and control loops) of your project. Network Tree The network tree allows to maintain an overall view regarding the bus systems and the network architecture of the project. This helps you to manage and arrange the network components (Controllers, BACnet devices, LON devices, LON-objects, etc.) of your project(s). 13 Control Functions Tree (CARE XL-Web only) The control functions tree provides control functions and control macros which will be used in the control editor for creating control loops. Sizing the Tree Displays The size of the tree display can be varied by moving the split pointer/split bar up or downwards.Information and Editing Pane The right pane can look very different depending on the item selected in the logical plant tree, respectively in the network tree. It shows the properties for the selected item. For example, it can show the properties of the project such as name, client, units of measurement etc. or it can show the terminal assignment of a selected controller. 14 Example 1: Project Properties Example 2: Terminal Assignment 15 See Also Logical Plant Tree Network Tree Interactivity between Logical Plant Tree and Network Tree Basic steps ******************************************* PART 7 ******************************************* Quick Tours The following engineering steps are typical for Excel 800 / 600 / 500 / Smart / 100 / 80 / 50 controllers in CARE XL-5000 and are described in more detail in the subsequent sections: 1.Create Project 2.Set Global CARE Options 3.Create Controller 4.Create Plant 5.Create Plant Schematic 6.Modify Datapoints 7.Assign Datapoints to Controller 8.Develop Control Strategy 9.Develop Switching Logic 10.Create Time Program 11.Design and Configure C-Bus Network 12.Startup Controller 13.Generate Documentation For special information on basic engineering of LON controllers and BACnet controllers refer to the LonWorks Engineering and Excel Web Controller chapters. ******************************************* PART 8 ******************************************* Create Project Purpose Define project name, password, and general information such as reference number, client name, and order number.

RESULT: The new plant is created and automatically attached to the controller. It is displayed in the logical plant tree. On the right pane, the plant properties are displayed. 11. Continue by Creating the Plant Schematic. 21 ******************************************* PART 11 ******************************************* Create Plant Schematic Purpose To provide control over the system operation. To get a good control of the plant a minimum number of datapoints are required. These datapoints are automatically created by drawing a graphical plant schematic or by quickly creating datapoints without graphics. Both procedures can be combined. NOTE: For the Excel Web controller (CARE XL-Web) schematic creation is not possible. NOTE: For the ELink controller, schematic and quick datapoint creation is not possible. Draw Plant Schematic When drawing a plant schematic you define the equipment of the plant and how it works together. A plant schematic is a combination of graphical segments such as boilers, heaters, and pumps. Segments consist of equipment such as sensors, status points, valves, and pumps. Each segment has an associated minimum number of datapoints required for good control. Creation of HW/SW Points without Graphic In comparison to drawing a plant schematic, datapoints without graphics can quickly be generated. These quick creations can include hardware as well as software points. For detailed information on point types, please refer to the PLANT SCHEMATICS section. 22 Procedures A) Draw Plant Schematic 1. If not already highlighted in the logical plant tree, select the plant. 2. Click menu item Plant, then drop-down item Schematic. RESULT: The Schematic Main Window displays. 3.Click menu item Segments, then select the desired component to insert it into the plant. 23 4. Add the following components by selecting the corresponding menu sequences:, Dampers/Outside, Return and Relief/Mixing Damper/No Minimum Damper , Sensor/Temperature/Mixed Air , Safeties/Freeze Status , Filter/Outside, Mixed or Supply Air Duct/Differential Pressure Status , Coil/Hot Water Heating Coil/Supply Duct/3-Way Valve/No Pump , Chilled Water Cooling Coils/Supply Duct/3-Way Valve/No Pump , Fan/Single Supply Fan/Single Speed with Vane Control/Fan and Vane Control with Status , Sensor/Temperature/Discharge Air Temp , Sensor/Pressure/Supply Duct Static 5. When finished the drawing, click menu item File, then submenu item End. RESULT: In the logical plant tree, the datapoints assigned to the plant components are displayed. 24 6. If desired, continue with adding HW/SW points without graphic to the schematic as described in the Quick Creation of HW/SW Points without Graphic procedure. B) Quick Creation of HW/SW Points without Graphic 1. If not already highlighted in the logical plant tree, select the plant. 2. Click menu item Plant, then drop-down item Create HW/SW Points. Or, click right mouse key and with left mouse key, click on Create HW/SW Point(s) in the context menu. RESULT: The New Point dialog box displays. 2. 5. 3. From the Type drop-down listbox, select the datapoint type and, if available, from the Subtype drop-down listbox, select the datapoint subtype. 4. In the Number field, select the number of points to be created and in the User Address fields enter the name of the datapoint(s) to be created. If you are adding more than one point, software automatically numbers the corresponding user addresses sequentially to guarantee unique user addresses. For example, if you enter pt and request two points, software creates two points named pt1 and pt 2. Only use alphabetic characters. Do not use blanks. 5. Click OK. RESULT: In the following example, the datapoints are added to the Analog Input type folder in the logical plant tree. 6. To view the plant schematic, click on the plant in the logical plant tree and select the Schematic tab on the right pane. 7. Continue by Modifying Datapoints. 25 ******************************************* PART 12 ******************************************* Modify Datapoints Purpose To customize point attributes according to desired system operation. Points can be modified in two different views, in the itemized display and in the grid display (for display options, see Basic Working Techniques section). The itemized display is suited for editing only a few datapoints, the grid display is suited for editing many datapoints in an overall view. Procedures A) Modify Datapoints in Itemized Display 1. In the logical plant tree, select the point you want to modify. RESULT: On the right pane, the point attributes are displayed on the Properties tab. 26 2. Modify desired values in the fields and/or select/deselect desired options. 3. Continue with assigning datapoints to the controller as described under the Manually Assign Datapoints to Controller section. B) Modify Datapoints in Grid Display 1. In the logical plant tree, select the plant of which datapoints you want to edit and select the Grid tab on the right pane. RESULT: All datapoints assigned to that plant are displayed in a grid. 2. Modify desired values in the fields and/or select/deselect desired options. 3. Continue by assigning the datapoints to the controller. 27 ******************************************* PART 13 ******************************************* Manually Assign Datapoints to Controller Purpose To accommodate the terminal assignments in CARE to the physical cabling. When creating a plant schematic for a XL 50, 80, 100, 800, 500, 600, or Smart controller, CARE automatically assigns the datapoints of the plant to the appropriate hardware modules, for example, analog inputs are assigned to the XF521A module, digital outputs are assigned to the XF524A module of an XL 500 controller. But, the order of the datapoints on their module does not necessarily correspond to the physical cabling. Therefore in some cases, datapoints need to be moved on their module in CARE. On the other hand it is also possible to accommodate the physical cabling according to the CARE terminal layout. NOTE: For the XL 500/Smart and XL 800 controllers, the target hardware can be chosen among the following different module types: –Standard I/O (XF5..) –Panel IO (XF8..) –Distributed I/O (XFL5..) –Distributed I/O (XFL8..) –Open LON 28 Procedure 1. In the logical plant tree, select the controller. 2. On the right pane, select the Terminal Assignment tab. RESULT: The terminal assignments of the controller are displayed. 3. If datapoints need to be relocated, click on the datapoint and with pressed mouse key, move it to the target terminal. RESULT: The datapoint gets green as you move it over terminals, which it matches to. NOTE: You can move datapoints only to terminals, which match to the datapoint type. Over terminals, which do not match to the datapoint type, the datapoint gets black and is indicated via a forbidden symbol. 29 4. On the target terminal, release mouse key. 5. Continue by developing control strategy for the plant. See Also Modify Datapoints ******************************************* PART 14 ******************************************* Develop Control Strategy Purpose The control strategy for a plant consists of control loops that monitor the environment and adjust equipment operation to maintain comfort levels. For example, a control loop for an air handling system can turn on a return air fan when discharge air temperature in the return air duct is greater than or equal to 68 F(20 ºC). Control loops consist of a series of "control icons" that dictate a sequence of events. Control icons provide preprogrammed functions and algorithms to implement sequences of control in a plant schematic. For detailed information on control strategy development, please refer to the Control Strategy section. Example (CARE XL-5000): In the following you will add a PID control element to the plant. Procedure 1. In the logical plant tree, select the plant. 2. Click menu item Plant, then drop-down item Control Strategy. RESULT: The Control Strategy Main Window displays. 30 RESULT: The Control Strategy Main Window is divided in the following areas: , Title , Menu bar , Plant schematic , Physical point bar , Software point bar , Work space , Control icons The functions will be described by creating a new control loop in the following steps. 3. The sequence of operation requires control of the duct static pressure. 4. To create a new control strategy, click menu file, then drop-down menu New. RESULT: The Create New Control Loop dialog box displays. 5. Enter a name, e.g. Pressure for the control loop and click OK. RESULT: You can now select the control icons to place them into the workspace. 6. Click the PID control icon. 7. Click a free rectangle in the control strategy work space to place the control icon. RESULT: Software places the symbol in the rectangle. Software may then display a dialog box that asks for "internal parameter" information relevant to the control icon. In this case, the PID icon asks for proportional band, derivative time, integral action, minimum output, and maximum output. For this system the default values are fine. 31 8. Click OK. RESULT: Notice the control icon. The red color indicates that not all inputs and outputs are connected to the schematic. 9. To connect the icon to required inputs and outputs, double-click the icon to display an input/output dialog box that requests required variables. For example, the PID icon displays the following dialog box: The Y, X, and W variables need connection to either physical points, pseudopoints, and/or other control icons. Variables on the left (Y in this case) are outputs. Variables on the right (X and W in this case) are inputs. The two blank rectangles in the dialog box are editing fields where you can enter values to replace the physical connections. For example, in the PID dialog box, you can type an engineering unit table reference and value for the W variable, instead of connecting W to a point or control icon. For engineering unit, enter the corresponding index number. 10. To connect the icon, click a W, X, or Y check box, click a physical point at the schematic, then click the control icon in the dialog box. 11. To connect the sensor input, click on the X check box. 32 12. Select the static pressure sensor physical point by clicking the red arrow head on the far right. RESULT: The arrow head turns black indicating that it has been selected. 13. Click the control icon symbol in the dialog box. RESULT: a. The dialog box closes. b. The active control icon changes color to dark blue. c. Software adds a short connecting line leaving the icon from the X location. horizontal. Where they intersect d. Two lines appear in the work space. One line is vertical; one is each other is the focus point for mouse clicks. You can move these lines by moving the mouse: –When you move the mouse left or right, the vertical line moves left or right. –When you move the mouse up or down, the horizontal line moves up or down. 14. Move and click the intersection point to create connecting lines. Move the intersection point over the point arrow head until a cross, +, appears. Click the left mouse key to complete the connection. RESULT: Software connects the point and icon. 15. Now connect the W input of the PID control icon to the reference variable - a user definable setpoint. An alternative would be to use the editing fields in the control icon dialog box, which would fix the setpoint to the value entered. 16. To create a software point, click on a free position in the software point bar. Locate it near the relevant control icon. RESULT: The Create/Select Software Address dialog box displays. 33 The selected software bar position is displayed at the bottom line of the dialog box. The list displays all existing pseudopoints/flags including unassigned, assigned and connected, assigned and unconnected pseudopoints/flags. Unassigned and assigned points/flags can be distinguished by the following symbols: Assigned points: Pseudopoints/flags that reside on the software bar. Unassigned software points mapped to XFM parameters. Unassigned pseudopoints/flags or points in switching tables in folder color with point abbreviation. Unassigned software points mapped to internal datapoints of Exams. Each pseudopoint/flag type has its own colored folder, which can be empty or contain already created pseudopoints/flags. Each pseudopoint/flag type has its own colored folder, which can be empty or contain already created pseudopoints/flags. 17. Click the Pseudo Analog folder. 18. click menu item Edit, then drop-down item New. 34 or Click right mouse button, and with left mouse button click New in the context menu, RESULT: The New Software Datapoint dialog box displays. 19.

To connect the PID control icon to the software point, double-click the control icon once to open it. 21. Click the W checkbox, then click on the VA software point you have been created. 22. Click the control icon symbol in the control icon dialog box. RESULT: Notice that there is a red line leaving the control icon from the W location. 23. Complete the connection, by clicking on the software point in the software point bar. 35 24. To finally connect the PID control icon?s output to the dampers on the fan, double-click the control icon once to open it. 25. Click the Y checkbox, then click the violet arrow head beneath the fan. RESULT: The physical point is now black indicating that it has been selected. 26. Click the control icon symbol in the control icon dialog box. RESULT: Notice that there is a red line leaving the control icon from the Y location. 27. Complete the connection, by clicking on the physical point previously selected. RESULT: The PID icon changes color to light blue to let you know that the PID is correctly connected to your system. This completes the sequence of operation for the static pressure. When the fan is on, control strategy modulates the damper to maintain static pressure at the setpoint. When the fan is off, the switching logic will place the damper in the minimum position. 28. Click menu item File, then submenu item Exit. 29. To check the control loop connections, click OK in the End Control Strategy dialog box. 36 30. CARE verifies that all control loop connections are complete by the following Information dialog box. 31. Confirm the Information dialog box by clicking OK. 32. Continue by developing the switching logic for the plant. ******************************************* PART 15 ******************************************* Develop Switching Logic Purpose Switching logic provides a convenient means to implement digital (Boolean) logic control of a point. An analog or digital point is commanded to a specific value or state if a certain set of conditions are met. Time delays can also be added. For example, switching logic can start a return air fan 30 seconds after a supply air fan starts. For detailed information on switching logic development, please refer to the Switching Logic section. Example (CARE XL-5000): According to the sequence of operation, the dampers of the fan will be placed in minimum position in case of fan failure. Procedure 1. In the logical plant tree, select the plant. 2. Click menu item Plant, then drop-down item Switching Logic. RESULT: The Switching Logic Main Window displays. The Switching Logic Main Window is divided into the following areas: , Title bar , Menu bar , Control bar , Plant schematic , Switching table (Work space) , Switching logic icons toolbox The functions will be described by adding switching logic tables in the following steps. 37 3. To begin a switching logic for the dampers, click on the fan address point (violet arrow head, 1) that controls the dampers. 38 RESULT: The title " SaFanVolCtrl" is the user address for the damper input point on the fan. The default of "0.000" matches the condition required by the sequence of operation. No change is required. We will use the status of the fan to determine when the damper will return to minimum position. 4.Click the green arrow head representing the fan status physical point (2) to add it to the current switching table. RESULT: According to the sequence of operation, the dampers of the fan will be placed in minimum position in case of fan failure. The field containing the "-" should indicate the status of the fan when you want the damper to be closed. 5. Click the "-" field twice to change it to a "0" (a false or off condition). 39 RESULT: The switching table is now complete. If the fan status is "0" false or off), the damper will be placed in a minimum position. The system also needs a table to open the heater valve under freeze conditions. The new button from the button bar is used to start a new switching table. 6. Click thebutton on in the control bar. RESULT: The following dialog box displays. 7. Save the switching table by clicking OK. RESULT: The violet arrow head for the fan dampers is now cross hatched. This indicates that a switching table is assigned to the point. 8. To start a switching table for the heating coil, click on the heating coil control point (second violet arrow head from left, 3). RESULT: The title "HtgVlv" is the user address for the hot water valve. The default of "0.000" represents a fully closed valve. We need to change the condition to fully open. 9. Click the third column once to change 0.000 to 100. 40 10. Type 100 and press ENTER key to fully open the heater valve if the switching conditions are met.RESULT: The heater valve is now set to 100 % open when the switching table conditions are met. Now we will specify those conditions. The temperature of the freeze status is one input that should determine the position of the heater valve. 11. Click the green arrow head (left from the heating coil control point, 4) representing the freeze status physical point. RESULT: The title "Frz Stat" is the user address and the "-" is a true/false or on/off condition. The arrow head representing the physical point turns black to indicate which point is active. Clicking the "-" toggles between "-", "1" and "0". 12. Click the "-" field once to turn it to a "1". 13. For this plant, we want to add an "OR" function with the next step. This is accomplished by adding an additional column. 14. Click the + COL icon on the switching logic icons tool box once. RESULT: The column is inserted. 15. The heater valve will open to 100 % if the freeze status is active. We also need to open the heater valve if the mixed air temperature is less than 34 degrees Fahrenheit. 41 16. Click the red arrow head representing the mixed air temperature sensor physical point (second from left, 5). RESULT: The title "MaTemp" is the user address for the mixed air temperature sensor. The "0" below on the left represents the temperature that activates the condition. The "0" on the right indicates the deadband before the condition is deactivated. The first change needed on this table is to toggle the "=>" to a "<=" sign. 17. Click the "=>" to change it to a "<=" sign. 18. The "0" in the left column represents the temperature that activates the condition. Entering a 34 in the left column indicates you wish to activate the heater valve when the temperature is less that or equal to 34 degrees Fahrenheit. 19. To change the temperature to 34, first click the "0" in the left column. 20. Then type "34" and press ENTER key. 21. The "0" in the second column represents how much the temperature will rise above 34 degrees Fahrenheit before the condition is no longer active. A deadband of 2 degrees is appropriate for this system. 22. Click the "0" field once to enter the deadband. 23. Type 2 and press ENTER key. 24. The field on the far right is where the "or" condition is entered. Clicking the"-"field" cycles through three conditions: "-" which is neutral, "1"which is true, and "0" which is false. 25. Click the "-" field" once to turn it to a "1" (true). RESULT: The table is now complete. When the freeze status is active or the mixed air temperature is equal to or below 34 degrees Fahrenheit, the hot water valve will be opened to 100 %. 26. Click menu File, then drop-down menu Exit. 27. Save the switching table by confirming with OK in the dialog box. 28. Continue by Creating a Time Program See Also Develop Control Strategy ******************************************* PART 16 ******************************************* Create Time Program Purpose Create time sequences for controller operation of devices. For example, set HVAC start and stop times. Time Programs implement these command schedules. 42 A controller can have a maximum of 20 time programs. Every time program created will be performed by the controller. Each Time Program specifies a list of datapoints to command. A Weekly Program defines the normal daily activity of the system by specifying which Daily Programs a controller should use for each day of the week (Sunday through Saturday). The Weekly Program applies for each week of the year. There is only one Weekly Program per Time Program. Daily Programs list points and point actions and times for the controller to implement. Holiday programs define special daily programs for holidays such as Christmas and Easter. Yearly Programs define time periods with special daily programs. Yearly programs are suited to consider specific local conditions, for example, regional vacation and public /religious festivals. Yearly programs can be defined for more than one year. The following procedure describes the time program handling in CARE XL-5000. For the handling in CARE XL-Web, please refer to the Schedules and Calendars section. Procedure (CARE XL-5000) 1. In the logical plant tree, select the controller. 2. Click menu item Controller, then drop-down item Edit and Time Program Editor. RESULT: The Time Program Editor displays. 3. Click menu item Edit, RESULT: The Time Program dialog box displays. 4. Click Add. RESULT: The Add Time Program dialog box displays. 5. Enter name for the time program and click OK, 6. The ACTIVE holiday radio button enables the Holiday Program. To disable the Holiday Program, click the INACTIVE holiday radio button. If holiday is inactive, this Time Program uses the Daily Programs, as set up by the Weekly Program, on holidays. RESULT: The Time Program dialog box redisplays. It shows the name of the overall time program to which then you can add daily, weekly, holiday and yearly programs. 7. Click Edit. 43 RESULT: The Time Program: dialog box displays. See Also Create Daily Program ******************************************* PART 00 ******************************************* General Errors Message Description Alarm Message An Alarm message dialog box may display after a controller download. Example: The box displays date and time, user address and value/status (if relevant), and an alarm message. This Appendix lists some of the alarm messages that can display. Communication problems When you exit CARE, the serial port used for communication with controllers may remain in use and thus be unavailable to other software applications. You can use the Control Panel 386 Enhanced function to issue a warning message whenever two applications attempt to control the same COM port. The 386 Enhanced function dialog box lists available COM ports in the Device Contention box. Select the COM port CARE uses and enable the Always Warn option. When the warning message occurs, reset the serial port. The Windows Terminal function can usually release the serial port and make it available for the next application. Start the Terminal function. The Terminal window displays with a menu bar that includes a Settings item. Select Settings, then the Communications drop-down item. When the Communications dialog box displays, select the COM port in question, click OK, and then exit the Terminal function. 44 Try running the new application. If the application will not communicate (for example, no data is available), close the application, reboot the PC, and restart the application.
