Overview

The PM862 controller CPU board integrates essential components such as the microprocessor, RAM, a real-time clock, LED indicators, an INIT push button, and a CompactFlash interface. It supports high availability with CPU redundancy, encompassing the CPU, CEX-Bus, communication interfaces, and S800 I/O.

The base plate of the PM862 features:

• Two RJ45 Ethernet ports (CN1, CN2) for Control Network connections.
• Two RJ45 serial ports (COM3, COM4).
  • COM3: RS-232C with modem control signals.
  • COM4: Isolated port for configuration tools.
