Material Composition:

  • PCB: Multi-layer FR-4, 6-layer design for signal integrity
  • Connector: High-density edge connector, gold-plated
  • Battery: CR2032 lithium coin cell for memory retentivity
  • Housing: ABS plastic, UL listed

Working Principle: The CPU continuously scans the user program in a cyclic manner. During each scan cycle, it reads all input states, executes the logic program, and writes all output states. The scan time is deterministic and typically under 10ms for moderate-sized programs. Communication tasks are handled via interrupt-driven routines, ensuring real-time data exchange with HMI panels, SCADA systems, and other PLCs. Installation Requirements:

  • Install in slot 0 of the IC200 chassis (CPU must be in the leftmost slot)
  • Requires IC200PWR102B or equivalent power supply in the same chassis
  • Connect programming port (RS-232) to a PC running Proficy Machine Edition
  • For Ethernet communication, install IC200CMM002 communication module

Usage Notes:

  • Never remove the CPU while the PLC is running unless using hot-swap procedure
  • Replace the battery every 5 years even if the PLC is powered — the battery degrades over time
  • Keep a backup of the program on a USB drive or network share
  • Do not exceed 128 total I/O points without using expansion chassis
