PM866AK01 is the core processor unit in the ABB AC 800M controller series, belonging to the "central processing unit" of industrial control systems. Its main functions are to execute control programs, process I/O data, and achieve communication and interaction with other modules. It is the core computing carrier of the 800xA automation system (especially version 6.0), suitable for medium and large-scale process control scenarios in chemical, power, manufacturing and other fields.
Data exchange and storage: Communicate with remote control units through RCU Link, while relying on memory backup batteries to ensure that key control parameters and programs are not lost after power failure, and the system can be quickly restarted after power restoration.
