FOXBORO  FEM100   Fieldbus Expansion Module

The Fieldbus Expansion Module (FEM100) provides four Expanded Fieldbuses to the Field Control Processor 270 (FCP270). Each of the four Expanded Fieldbuses can accommodate up to thirty-two 200 SeriesFieldbus Modules (FBMs).

The FEM100 module provides four Expanded Fieldbuses to an FCP270 to increase the number of 200 Series (or equivalent) FBMs supported by the FCP270 modules. The FEM100 module supports the 2 Mbps HDLC module Fieldbus for communication between the FCP270 and the 200 Series FBMs.

The FEM100s are installed in a DIN rail mounted Modular Two-Slot or Four-Slot Expansion Baseplate for 2 Mbps communication between the FBMs and FCP270 modules.

The FEM100 is used exclusively with the FCP270. It is not used with other control processors, such as the FCP280.

For typical control usage enables a FCP270 to communicate with up to 128 of the 200 Series FBMs, over four Expanded Fieldbuses.

Redundancy minimizes communication interruption from Expanded Fieldbus 1 through 4 Two-Slot and Four-Slot FEM100 Expansion Baseplates both support the 2 Mbps Module.

Fieldbus for 200 Series (or equivalent) FBMs.

Two-slot Expansion Baseplate accommodates FEM100 modules only, used to upgrade existing FCP270 installations.
