FCM2F2

Fieldbus Communications Module

The Foxboro FCM2F2 is a fiber-optic communications extender for 200 Series Fieldbus Modules. It allows fieldbus modules to be positioned closer to the plant process while maintaining communication with the associated baseplate through a fiber-optic link.

The FCM2F2 supports a nominal maximum baseplate-to-baseplate fiber distance of 2 km (1.24 mi). Fiber transmission also provides electrical isolation and strong resistance to EMI, RFI and lightning-related interference, making the architecture suitable for electrically demanding industrial environments.

The optical link separates the remote fieldbus section from the electrical connection between baseplates. This helps protect communication from voltage differences and ground-loop conditions.

Fiber communication is not affected by EMI, RFI and lightning in the same manner as long electrical signal runs, making it useful around rotating machinery, arc welders and high-voltage cable routes.

A redundant arrangement uses paired FCMs on the baseplates, while a non-redundant configuration can use one FCM per baseplate.

Where FCM2F2 Fits

FCM2F2 is intended for installations where 200 Series fieldbus modules need to be separated from the control-side baseplate and positioned nearer to the process.

FCM2F2 mounts on a 200 Series FBM baseplate. A baseplate can accommodate up to eight FBMs or a combination of FBMs and FCMs. Baseplates within 60 m can also be linked using standard twinax-pair cable where an FCM fiber extension is not required.

For a redundant fiber connection between two baseplates, a pair of FCMs is used on each baseplate. A non-redundant configuration uses one FCM on each baseplate.
