1. General Introduction
The base plate of the ABB PM861AK02 controller has two RJ45 Ethernet ports (CN1, CN2) for connection to the Control Network, and two RJ45 serial ports (COM3, COM4). One of the serial ports (COM3) is an RS-232C port with modem control signals, whereas the other port (COM4) is isolated and used for the connection of a configuration tool. The controller supports CPU redundancy for higher availability (CPU, CEX-Bus, communication interfaces and S800 I/O).
The controller CPU board contains the microprocessor and RAMS memory, a real-time clock, LED indicators, INIT push button, and a Compact Flash interface.
