Power supply: 24 V DC (19.2-30 V DC), power consumption 210/360 mA at +24 V
Built-in battery backup: Li-Ion, 3.6 V, for memory backup
Clock synchronisation: Ability to synchronise with other AC 800M controllers via the CNCP protocol
Control network protocols: supports MMS (Manufacturing Message Service) and IAC (Inter Application Communication)
RS-232C interface: two interfaces available, one for general purpose and one for service tools, with various baud rates
I/O capacity on Modulebus: up to 96 (single PM866) or 84 (redundant PM866) I/O modules
I/O capacity on Modulebus: up to 96 (single PM866) or 84 (redundant PM866) I/O modules
The base plate of the PM866 / PM866A 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).(PM891K01)
