1. General Introduction
The CPU boards of PM851AK01 controller contains the microprocessor and RAM memory, a real-time clock, LED indicators, INIT push button, and a Compact Flash interface. The base plate of the PM851A controller has two RJ45 Ethernet ports (CN1, CN2) for connection to the Control Network, and two RJ45 serial ports (COM3, COM4).Note that a PM851/PM851A is restricted to one Ethernet (CN1) port, thus redundant Ethernet is not available. 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. 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.
