The A and AnS series modules cannot be loaded on the base units given in the above table. Program Capacities and Large Standard RAM Capacities To construct small to large scaled systems, the Q series has a wide assortment of CPU modules (Note 3) having 8k to 252k step program capacities and up to 128k words, large-capacity standard RAMs (Note 4), enabling a selection of the CPU modules which matches the machinery/equipment control capabilities. Programs can also be stored in the memory card, and can be uploaded from the memory card by the dedicated instruction (PLOAD) and executed. This allows the program memory to be virtually extended. Extended Memory The high-performance model QCPU is equipped with a small PC card slot to insert up to 32MB (when using the ATA card) extended memory card.

Variable Time Constant of Input Module The DC input module's input response time can be changed. The response time can be selected according to your application, e.g. response time of 0.1ms (Note 8) for fast response or 70ms for a reliable response (in consideration of noise margin, etc.).

Modules are managed CPU-by-CPU. You can use Q series I/O and intelligent function modules as it is (Note 1). Management Setting parameters with GX Developer makes multiple PLC system construction easy. (Note 2) By merely linking GX Developer to one CPU, you can execute programming/ monitoring function on other CPUs without swapping cables. (Note 3) The Q series can utilize a multiple PLC system where multiple high-performance CPUs are loaded on the same main base to manage I/O and intelligent function modules CPU-by-CPU in a control system. In the multiple PLC system, you can choose CPUs according to your application. With the multi-CPU system, inter-CPU communication uses two methods, cyclic communication, which uses automatic refreshing for periodic communication, and transient communication, which uses dedlicated instructions for communications. This system allows the sequence control and data processing that were conventionally performed by a single CPU to be shared by multiple dedicated CPUs, improving speed and performance in the whole system and expanding its application range. Note 1: There are restrictions on the number and versions for intelligent function modules. Check details in the Q series data book.

PULL MODE RUN ERR POWERQ00JCPU PULL RS-232 Used with the Q series I/O and intelligent function modules, the QCPU basic model achieves a compact system of high performance, high functions and excellent cost performance. For example, a compact system can be configured by connecting the power supply-free Q5 B extension base to the Q00JCPU, a combination of a power supply, a CPU and a base. A network system can also be configured by loading an Ethernet, MELSECNET/H or CC-Link network module. The Q00JCPU is a CPU unit consisting of a CPU module, a power supply module and a main base unit (5 slots). (The power supply module is designed for 100 to 240V.) The Q00 and Q01CPUs are discrete CPU modules. Though the program capacity of the Q00J/Q00CPU is 8k steps and that of the Q01CPU is 14k steps, the small code size used for the program instructions allows creation of control programs about twice larger than those of the conventional A series. The device memory is 18k words, about five times greater than that of the AnSCPU. Also, it permits device assignment to be changed within 16k words. Further, the Q00/Q01CPU incorporates RAM as standard for use as file registers. The file registers have 32k words, about four times greater than those of the AnSHCPU. They allow a compact system to handle large volumes of data. The QCPU basic models contain flash ROMs. The standard CPU can perform ROM operation without using a memory card. (Unlike the AnSHCPU, you need not prepare a memory cassette.) You can perform write to flash ROM easily using GX Developer (Ver. 7 or later). (Such troublesome operation as to create a ROM with a ROM writer is unnecessary.) The Q00/Q01CPU basic models have a serial communication function. The RS-232 interface of the CPU can make communication with an external device that can communicate using the MC protocol. This function eliminates the need for a serial communication module, reducing costs. With an automatic CC-Link start, you can start CC-Link and refresh data without setting parameters, reducing the man-hours of parameter setting. The Q00JCPU can be used to configure a system consisting of a main base, an extension base and a GOT (bus connection) to be ready for system expansion.

The QCPU basic model does not accept the A/AnS series modules for extension. HIGHLY DEVELOPED CONTROL (2) The Q series has the multiple cpu system function which also permits PLC CPUs and motion CPUs to be loaded together, enabling utilization of their respective strong points and construction of an optimal system. A motion CPU can use SSCNET that rapidly controls up to 96 axes in a single system and saves wiring. A personal computer CPU can access I/O and intelligent function modules from a C-written application program. It can also communicate with higher level devices from an Ethernet communication port. A motion CPU is good at high- leveled, complex motion control. It can speed up motion operation cycles and control up to 32-axis per CPU. The Q173CPU (32 -axis) and Q172CPU (8-axis) are available. (For details, refer to the Q series motion controller manual.) The operation cycle is 0.8ms/8 axes, 1.7ms/16 axes or 3.5ms/32 axes. SSCNET is a network where the motion CPU and servo amplifiers are connected with minimum wiring by high-speed serial communication. Integration of Motion CPU and Personal Computer CPU Multiple Q series PLC CPUs can be used together to allow a single system to exercise controls different in tact time, e.g. sequence control and data processing.

When one process requires fast processing and the other does not, they can be handled respectively by two CPUs, providing stable (unaffected by the other process) and rapid control. The Q series Ethernet, MELSECNET/H and CC-Link have achieved seamless access beyond the differences in network type and network hierarchy. Data can be transferred between any networked PLCs and monitored/programmed with GX Developer. (Note 1) Seamless Communication Fast, Reliable Network MELSECNET/H Boards for Personal Computer The Q series has a wide assortment of personal computer boards compatible with the MELSECNET/H network system. These boards maintain the upward compatibility of the conventional MELSECNET/10 board, and use the dedicated software package for board setting to simplify troublesome work. Furthermore, the RAS functions installed ensure ease of error detection. MELSECNET/H Remote The high-performance model QCPU can configure a remote I/O network using the Q series I/O for large-scale, large-capacity centralized management and distributed control. In addition to 10Mbps compatible with the conventional MELSECNET/10, the MELSECNET/H has a choice of two operation modes: the MELSECNET/H mode having Max. 25Mbps transmission rate; and the MELSECNET/10 mode compatible with the conventional A/QnA series. In the MELSECNET/H mode, link scans are as fast as 10ms on a network of 8 stations having 2k link relay points and 2k link register points.
