ABB PM866AK01 Compact Product Suite Hardware Selector

The CPU board contains the microprocessor and RAM memory, real-time clock, LED indicators, INIT button, and CompactFlash interface.

The PM866 / PM866A controller's backplane has two RJ45 Ethernet ports (CN1. CN2) for connection to the control network and two RJ45 serial ports (COM3. COM4).

used to connect 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.

The other port (COM4) is isolated for connecting configuration tools.

The controller supports CPU redundancy for increased availability (CPU, CEX-Bus, communication interfaces and S800 I/O).

Easy DIN rail mounting/dismounting procedure using a unique sliding and locking mechanism.

All baseboards have a unique Ethernet address that provides hardware identification for each CPU.

This address can be found on the Ethernet address label on the TP830 backplane.
