ABB PM858K01 3BSE082895R1 Processor Unit

ABB PM858K01 3BSE082895R1 Processor Unit

Functional Description

The CPU board contains the microprocessor and RAM memory, a real-time clock, LED indicators, INIT push

button, and a CompactFlash interface.

The base plate of the PM858 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).

Simple DIN rail attachment / detachment procedures, using the unique slide & lock mechanism. All base

plates are provided with a unique Ethernet address which provides every CPU with a hardware identity. The

address can be found on the Ethernet address label attached to the TP830 base plate.
