GM7 & GM7U

CPU, digital I/O and power are embedded in block-type PLCs, which is easy to install in the area you want for system configuration. In case of module-type PLCs, system configuration is easily achieved by a variety of modules (CPUs, I/O, special modules, network modules).

Features

  • GLOFA-GM Network
    • Fnet, Rnet as master module
    • DeviceNet, Profibus-DP as slave module
  • Various built-in functions
    • High speed counter 1 point (1-phase 16kHz, 2-phase 8kHz
    • Pulse output 1 point (2kHz only available in Tr-output module)
    • PID loop with autotuning
    • Pulse catch 8 points (pulse catch: Min. 0.2ms)
    • Input filter (Noise reduction)
    • interrupt point: 8 points (Task program execution by external interrupt input)
    • RS-232C interface 1 channel (Built-in Cnet):dedicated, User-defined, Modbus protocol
