AEG MM-FMC3-010
Product Introduction:
The AEG MM-FMC3-010 is a dedicated Fieldbus Master Controller module designed for integration within the Modicon Quantum PLC platform. It serves as the primary communication gateway between the PLC CPU and Fieldbus networks, enabling seamless data exchange with distributed Fieldbus devices including sensors, actuators, remote I/O stations, and intelligent field instruments. This module offloads communication processing from the main CPU, ensuring deterministic real-time fieldbus operation.

Working Principle:
The MM-FMC3-010 module operates as an intelligent communication co-processor. It connects to the Quantum PLC backplane via the system bus, receiving process data from the CPU. The module independently manages all Fieldbus protocol stack operations — including token passing, telegram framing, CRC checking, and device addressing — and exchanges cyclic process data with connected Fieldbus slaves at configured intervals. Acyclic data requests are handled on demand by the CPU via the module’s shared memory interface.
