• [Redundancy System] CPU
    • Built-in Functions

      • PID Control
        • Operates 32Loops PID without PID module.
      • RTC (Except CP*A type)
        • Reads time from RTC and save it in F memory device.
      • Input and Output Reservation
        • Scans and detects module at designated slot.
        • Refers to reservation function which writes a program without I/O change in case of extension,
          damage or module replacement.
      • Online Edit
        • Scan program can be edited when CPU is RUN mode(Online).
      • RS-232 Port (XPnB, CP3C, CP3E, CP4E/F)
      • RS-422/485 Port (CP4D/U, CP4F)

      Self-Diagnostic Functions

      • Watch-Dog Timer
        • Detects delayed operation error in the program.
      • Module installation in Slot
        • Detects whether a module is installed in the slot.
      • Memory Error
        • In case of an Error the built-in Flash memory of CPU module or Dual Port RAM, will save the Error in the F memory device.
      • Battery Error
        • If the battery falls under the standard voltage, F3.4 will be turned ON.
      • Power Error
        • If the input voltage to Power module is lower than standard range, RUN and STOP lamp will blink.
