Equipped with an MPC862 processor, the module delivers strong computing performance suitable for multitasking and parallel processing. It supports up to 32 controller applications, each allowing a maximum of 64 programs and 128 charts. The controller can execute up to 32 tasks, with application cycle times as low as 1 millisecond, enabling fast execution of complex control logic across demanding industrial environments.

High-Reliability Redundancy Design

The module supports full CPU redundancy, providing a maximum switchover time of only 10 milliseconds. This ensures rapid, seamless transfer between primary and standby processors, preventing downtime caused by single-module failures. A built-in 3.6 V lithium backup battery and 2 MB of flash memory for firmware storage guarantee program and data retention during power loss or unexpected system events.

Flexible Communication and Synchronization

The CPU offers multiple communication interfaces, including:

Two Ethernet ports (IEEE 802.3 compliant, 10 Mbit/s)

Two RS-232C ports: one for general communication, and one dedicated to service/engineering tools

It supports MMS and IAC control network protocols, and allows millisecond-level clock synchronization between AC 800M controllers through the CNCP protocol. In data exchange scenarios, event transmission to OPC servers reaches 36–86 events per second, while general data message throughput is 113–143 messages per second, meeting industrial-grade real-time communication demands.

Excellent System Scalability

The controller supports extensive expansion through the CEX-Bus, allowing up to 12 communication modules. Its modular I/O architecture accommodates substantial expansion:

Non-redundant mode: 1 electrical cluster + 7 optical clusters

Redundant mode: 7 optical clusters

This architecture supports a wide range of I/O modules and allows the controller to scale from small process units to large, complex automation systems.
