Main Features
High-Speed Processing
Uses an MPC866 processor running at 133 MHz.
Executes approximately 1000 Boolean operations in 0.09 ms, suitable for demanding continuous process control applications.
Supports fast control cycles down to 1 ms depending on configuration.
Integrated Communication Interfaces

The PM866AK01 CPU base includes:

2 × RJ45 Ethernet ports
Used for AC 800M Control Network communication.
Supports redundant Ethernet communication architecture.
2 × Serial communication ports
COM3: RS-232C with modem control signals.
COM4: Isolated serial port for configuration tools.
Expandable Architecture

Supports connection with:

ABB S800 I/O modules
PROFIBUS DP communication modules
CEX-Bus communication modules
ModuleBus devices
AC 800M communication interfaces

The controller architecture allows modular expansion for large automation systems.
