Quickbuilder点参数modbus地址格式

Defining a Modbus Address for a Point Parameter给一个点参数规定一个Modbus地址 Entering an Address访问一个地址 For PV Source Address, Source Address, and Destination Address the format for an Modbus controller address is: 一个Modbus控制器地址的 PV源地址，源地址和目标地址格式 是： ControllerName Location控制器名字 位置 Part 部分 Description描述 ControllerName控制器名 The name of the Modbus controller. Modbus控制器的名字 Location 位置 The address within the controller where the value is stored. See Location Syntax. 这个值储存在控制器里的位置。查看 Location Syntax. If you would like help when defining an address, click next to Address to display Address Builder. 当你规定地址的时候如果你希望得到帮助的话，点击下一步去处理建立地址的显示 Using the Address Builder to Enter an Address用这个地址建立提示去建立地址 To specify a Modbus controller address, specify the items as follows: 制定一个Modbus控制器 地址，制定项目如下： Property 性能 Description 描述 Address Type 地址类型 Select Controller.选择控制器 Controller 控制器 Select the appropriate Modbus controller. 选择一个适当的Modbus控制器 Location 位置 The address within the controller where the value is stored. See Location Syntax. 这个值储存在控制器里的位置。查看 Location Syntax. Location Syntax 位置语法 The format for the location is:位置格式是： Address [DataFormat|BitNumber] 地址[数据格式|字节数] Part 部分 Description 描述 Address 地址 The address (decimal) for the parameter value within the controller table. 在控制器表格里参数值的地址 If the address is prefixed with the table number, omit the table number. For example, the first register in table 4 is often written as 40001 or 400001. Enter 1 as the address. 如果位址与表数目一起前缀，省略表数目。例如，在表 4 里的第一个注册位置经常 被写成 40001 或者 400001.写 1 作为地址。 The table number prefix is shown on the Scanning tab of the Point Detail display and when you use the commands listag, rtusum and lisscn. 前缀的桌面数被显示在点细节显示扫描界面 当你用 listag, rtusum 和 lisscn 命令时 DataFormat 点格式 The data format acronym or starting bit number, depending on how you want the value to be read: 点格式的首字母缩写或者起始位数字，取决于你想用哪个值读取 Data Format for Scaling 16-bit Integers 16位整形缩放比例的点格式 Data Format for Reading Floating Point Values 浮点数的点格式 Data Format for Reading Raw Values Without Scaling 没有缺陷的不成熟点的数据格式 If you want to use a user-defined data format, you must define the format on the server. See the Configuration Guide for details. 如果你想用一个用户自定义的点格式，你必须在服务器上定义这个格式，查看 the Configuration Guide for details. BitNumber 位数 Only applicable to Input Register and Holding Register data tables. The starting bit number, ranging from 0 (default) to 15, where 0 is the right-most bit in the 16-bit register. 仅仅适用于输入寄存器和保持寄存器的数据表。起始位数从 0到 15，0在 16位里是最右边 的 Analog and accumulator point parameters can read up to 16 bits模拟和累加点是 16位. Status point parameters read 1, 2 or 3 consecutive bits. 位参数读 1,2,或者 3连续 Example例如 Analog point模拟量点 PV source: 161 U4095 PV源：161 U4095 SP destination: 162 U4095 SP目标：162 U4095 Mode destination: 25 1 方式目的：25 1 Status point 状态点 PV source: 26 PV 来源：26 Accumulator point 累加点 PV source: 171 C16 PV来源：171 C16 Data Format for Scaling 16-bit Integers 16位整形资料格式 You can scale point parameter values with a data format if they have addresses in the Input Register and Holding Register data tables. Select the format that corresponds to the counts that have been set in the controller register. Data Format Counts in Controller Register U4095 (default) 0 to 4095 U9999 0 to 9999 U999 0 to 999 U15B 0 to 32767 U16B 0 to 65535 S16B -32768 to 32767 Note: If auxiliary parameters have a data format type that requires scaling (U4095, U999, and so on), they take the same range as the PV. Data Format for Scaling 32-bit Integers The Modbus Interface will combine two 16-bit registers (as defined by the Modbus protocol standard) into a 32-bit value. The little-endian word formats listed in the following table. Data Format Description Counts in Controller Register S32B Unsigned 32-bit Binary Little-endian Not scaled U32B Unsigned 32-bit Binary Little-endian Not scaled S32BS Signed 32-bit Binary Scaled Little-endian -32768 to 32767 U32BS Signed 32-bit Binary Scaled Little-endian 0 to 65535 These data formats assume the following word/byte order: two 16-bit registers in big endian byte order the first register transmitted is the low word the second register transmitted is the high word The value is calculated as (high register x 65536) + low register. The big-endian word formats listed in the following table. Data Format Description Counts in Controller register U32BB U32BSB S32BB Unsigned 32-bit Binary Big-endian Not scaled Unsigned 32-bit Binary Scaled Big-endian 0 to 65535 Signed 32-bit Binary Big-endian Not scaled S32BSB Signed 32-bit Binary Scaled Big-endian -32768 to 32767 These data formats assume the following word/byte order: two 16-bit registers in big endian byte order the first register transmitted is the high word the second register transmitted is the low word The value is calculated as (high register x 65536) + low register. Data Format for Reading Floating Point Values Select format IEEEFP to read two consecutive registers as a single precision floating point number. Variations on the IEEEFP format that you can specify include: Format Description IEEEFPB Bytes are big endian format (this is the same as IEEEFP) IEEEFPBB Bytes are byte-swapped big endian format IEEEFPL Bytes are little endian format IEEEFPLB Bytes are byte-swapped little endian format Note IEEEFP numbers use two data addresses, address and address-1. Do not specify address-1 (the lower address) as the point parameter location address. When configuring controller data tables, do not assign overlapping data addresses if floating point values are used and do not set an IEEEFP address to 1. Data Format for Reading Raw Values Without Scaling Select a format of C16, or enter a 0, to read all 16 bits in the register without scaling. To read less than 16 bits without scaling enter the starting bit number (1 to 15). If you are not using scaling, the point range is still used for PV indicator bar height only (the PV indicator bar is on the Point detail display on Station).
