ABB PM866AK01 3BSE076939R1 Processor Unit Module---The controller has two RJ45 Ethernet ports (CN1, CN2) and two RJ45 serial ports (COM3, COM4) on the base plate for connecting to the control network. One of the serial ports (COM3) is the RS-232C port with the modem control signal, while the other port (COM4) is isolated and used to connect to the configuration tool. The controller supports CPU redundancy and provides higher availability (CPU, cex bus, communication interface, and S800 I/O).The CPU board contains the microprocessor and RAM memory, a real-time clock, LED indicators, INIT push button, and a CompactFlash interface.
