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 PM856AK01 3BSE066490R1 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.
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.

FAQ
Q: What hardware does the PM856AK01 3BSE066490R1 include?
A: The PM856AK01 3BSE066490R1 includes a PM856A CPU module and a TP830 socket terminal unit.
Q: Is its part number PM856AK01 3BSE066490R1 unique?
A: Yes, the PM856AK01 3BSE066490R1 uses 3BSE066490R1 as a unique ABB order code to identify this specific kit.
Q: Does the PM856AK01 3BSE066490R1 support CPU redundancy?
A: No. The PM856AK01 3BSE066490R1 does not support CPU redundancy. For redundancy, PM861 or PM864 and later models are recommended.
Q: How much more memory does the PM856AK01 3BSE066490R1 have compared to PM851?
A: The PM856AK01 3BSE066490R1 has 16MB memory, which is twice the PM851’s 8MB capacity.
Q: Does the PM856AK01 3BSE066490R1 support hot-swapping?
A: The CPU of the PM856AK01 3BSE066490R1 can technically be removed from the socket while powered, but this is not recommended during production; the socket connection must remain secure.
