GE-FanucIC630CCM310ASeries Three I/O Link Local Communications Module, Twisted Pair

Product Description

What this part is

A GE Fanuc Series Three I/O Link Local communications module, IC630CCM310A, using a twisted-pair link. It fits in the Series Three base at the processor end of a remote I/O link and drives the link out to a remote I/O station, so a rack of I/O can be placed near the machine instead of running every field wire back to the main panel.

It is a communications module. The Local designation is the important word: this is the processor end of the link, and the remote end is a separate module.

Decoding the order code

IC: GE Fanuc Automation industrial controls prefix.

630: the Series Three PLC family. This is the field most likely to be misread, because the GE Fanuc groups do not interchange. IC610 is Series One, IC600 is Series Six, IC630 is Series Three, IC655 is Series Five, IC693 is Series 90-30 and IC697 is Series 90-70.

CCM: the module class, communications and computer-interface modules. Series Three I/O modules carry MDL instead.

310: the specific module, here the I/O Link Local end, twisted-pair media.

A: the hardware revision letter. A revision suffix, not a different product.

What these specs mean in practice

An I/O link runs between a Local at one end and a Remote at the other; two Locals will not talk to each other. This is the processor-end module.

The media matters as well. This is a twisted-pair link, not fibre and not coax, so the interconnecting cable is a suitable shielded twisted pair, correctly terminated, and routed clear of motor and drive cabling. On legacy serial I/O links the overwhelming majority of intermittent remote-station faults turn out to be cable, shield or termination problems rather than module failures.

Series Three is a long-discontinued platform, and the link is a matched set: base, power supply, processor, link modules at both ends and the I/O modules are all Series Three parts.

Published specifications

Function: I/O Link Local communications module, processor end of a remote I/O link.

Platform: GE Fanuc Series Three programmable controller.

Link media: twisted pair.

Slot occupancy: one slot in a Series Three base.

Quantity and configuration

Sold as 1 piece — one Link Local module, the processor end of the link. The matching remote-end module, the base and power supply, the twisted-pair link cable and its terminations, and the I/O modules are separate items in the Series Three system.

Interchange guidance

Searchable equivalents of the same part: IC630CCM310A, IC630CCM310, IC630-CCM-310-A, IC630 CCM 310 A, IC630CCM310-A. Other revision letters of IC630CCM310 are the same module at a different revision. Distinct parts: the remote-end module of the same link carries a different number, and IC610 Series One, IC600 Series Six and Series 90 family CMM modules are different platforms, different backplanes and different links.
