Programmable Controller CQM1H The CQM1H’s rack-less modular design lets you customize your control system by adding “inner boards” for advanced functions, as well as specialized I/O and communications modules. CQM1H offers the most flexibility of all PLC systems in its class. D D D D D D D D D D 4 different base CPUs to choose from; 16 DC inputs built in; expands up to 512 points No separate backplane required Inner Boards allow “customized” configuration of the CPU Serial communications inner board supports protocol macro feature for communication with third-party serial devices Supports all existing and new CQM1 I/O and specialized I/O modules Optional memory cassettes allow backup of sensitive data, provides a real-time clock ControllerLink network transmits 8 kword data packets at up to 2 Mbps; 32 nodes Advanced instruction set includes PID, floating point math, protocol macro instructions and more CompoBus/S, SYSMAC BUS and AS-interface masters support remote I/O Up to 15.2 kwords of program memory Basic Configuration Select the CPU and I/O modules (discrete, analog and dedicated special function types) then determine the power supply based on the current consumption. The I/O Control and Interface adapters give you the option of dividing the CPU and I/O system into two narrower units than the examples shown below. The CQM1H-CPU51/CPU61 models offer space-saving position and motion control solutions as well as additional analog and serial communications capabilities right at the CPU. CQM1H modules are assembled with connectors on their sides. 256 or 512 I/O points max.

Input interrupts (4 inputs max.) Counter Mode: Interrupts are executed in response to reception of a set number of pulses (counted down) via the CPU’s internal built-in input points (4 points). Interval timer interrupts (3 timers max.) Scheduled Interrupt Mode: Program is interrupted at regular intervals measured by one of the CPU’s internal timers. High-speed counter interrupts Target Value Comparison: Interrupt is executed when the high-speed counter PV is equal to a specified value. One-shot Interrupt Mode: An interrupt is executed after a set time, measured by one of the CPU’s internal timers. Range Comparison: Interrupt is executed when the high-speed counter PV lies within a specified range. Counting is possible for high-speed counter inputs from the CPU’s internal input points, Pulse I/O Boards, or Absolute Encoder Interface Boards. (The High-speed Counter Board has no interrupt function, but can output bit patterns internally and externally.)

Min. cycle time 1 to 9,999 ms (Unit: 1 ms) Cycle time monitoring When the cycle time exceeds 100 ms, the Cycle Time Over Flag turns ON, and operation continues. (A setting can be made in the PLC Setup so that this error is not generated.) When the cycle time exceeds the cycle monitor time, operation is stopped. Cycle monitor time settings: 0 to 990 ms in 10-ms units, 0 to 9,900 ms in 100-ms units, 0 to 99 s in 1-s units. The maximum and current values of the cycle time are stored in the AR area. I/O refreshing Cyclic refreshing, refreshing by IORF(97), direct output refreshing (set in the PLC Setup), interrupt input refreshing. (The inputs that are refreshed can be set separately for input interrupts, high-speed counter interrupts, and interval timer interrupts in the PLC Setup.) I/O memory status when changing operating mode Depends on the ON/OFF status of the I/O Hold Bit (SR 25212). Load OFF All outputs on Output Units can be turned OFF when the CPU is operating in RUN, MONITOR, or PROGRAM mode. (Used for stopping output in emergencies, for debugging, etc.) A pin setting on the DIP switch on the front of the CPU is stored in AR 0712. This setting can be used as an ON/OFF condition (e.g., to switch between trial operation and actual operation). Possible User-customized DIP switch setting Mode setting at power-up Debugging Online editing Program protection Error check Forced set/reset, differential monitoring, data tracing (scheduled, cyclic, or when instruction is executed). User programs can be overwritten in program-block units when the CPU is in MONITOR mode. With the CXProgrammer, more than one program block can be edited at the same time. Write-protection of user program and data memory (DM 6144 to DM 6655: read-only DM): Set using pin 1 of the DIP switch. User-defined errors (i.e., user can define fatal errors and non-fatal errors using the FAL(06) and FALS(07) instructions.) (It is possible to stop operation using FALS(07) for fatal errors. User-defined error logs can be created in specific bits (logging) when using FAL(06). Error log Serial communications Up to 10 errors (including user-defined errors) are stored in the error log.

Commands to a host computer Remote programming and monitoring Host Link command responses can be sent to a computer connected via the Host Link System using the TXD(—) (communications port output) instruction. Host Link or peripheral bus communications via a CPU’s serial communications port can be used for remote programming and remote monitoring of the PLC through a Controller Link System. (This function is, however, not supported for the serial communications ports on the Serial Communications Board.) Program check Program is checked at the beginning of operation for items such as no END(01) instruction and instruction errors. CX-Programmer can also check programs. (The level of program checking can be set.) Battery life 5 years at 25_C (Depends on the ambient temperature and power supply conditions.
