I/ASeries® Hardware

Fieldbus Communications Module, FCM10E

The FCM10E Fieldbus Communications Module is a

communications interface which allows the DIN rail

mounted Fieldbus Modules (FBMs) to communicate

with I/A Series control stations via the high speed,

optionally redundant 10 Mbps Ethernet trunk Fieldbus

(see Figure1).  The FCM10E converts 10 Mbps

Ethernet signals used by the control station to 2Mbps

signals used by the FBMs, and vice versa.  They also

provide galvanic isolation between the 10 Mbps

Ethernet trunk Fieldbus and the 2Mbps module

Fieldbus.

The FCM10E modules are used in pairs for

redundancy.  An FCM10E (or pair of FCM10E

modules) can support up to 30 FBMs.

FCM10E modules have a compact design, with a

rugged extruded aluminum exterior for physical

protection of the circuits.  Up to 30 FCM10E pairs can

be connected to the Ethernet trunk Fieldbus.

Enclosures specially designed for mounting of DIN

rail mounted FBM equipment provide various levels of

environmental protection for the Fieldbus

Communications Modules, up to harsh environments

per ISA Standard S71.04.

The FCM10E can be removed/replaced without

removing power or communications cabling.

Six light-emitting diodes (LEDs), incorporated into the

front of the FCM10E Fieldbus Communications

Modules, indicate the status of network activity

to/from the control station and the associated FBMs,

and the operational status of the FCM10E.

For redundant configurations, two FCM10E modules

are required for each FBM grouping. A non-redundant

configuration requires a single FCM10E for each

grouping. Figure1 shows how FCM10E modules are

used in a typical subsystem configuration.

BASEPLATE MODULE MOUNTING

The FCM10E mounts on a baseplate, which is either

DIN rail mounted or rack mounted and includes signal

connectors for Fieldbus, power, and I/O cable

connections. A baseplate can support up to eight

FBMs, or a combination of FBMs and FCMs.
