More Information

Overview Manuals Network Links Time Sync Redundancy Application
  • Use FCM100Et only in the documented redundant ZCP270 fieldbus architecture
  • Maintain both 100 Mbps optical network paths and the 2 Mbps Module Fieldbus
  • Preserve external time-strobe wiring when SOE or TDR/TDA synchronization is required

FCM100Et is a Foxboro redundant fieldbus communications module with time synchronization designed for the Foxboro Fieldbus Communication Modules family.

Foxboro FCM100Et is a redundant Ethernet-to-Module-Fieldbus communications module that links DIN-rail FBMs with ZCP270 control through The MESH network. The official document styles the function as FCM100Et and identifies P0926GS as the module part number; splitter/combiners, fiber cables and baseplates are separate hardware.

Before installation or replacement, verify the complete nameplate, compatible hardware, network or field wiring, saved configuration, software release and commissioning plan.

Availability, condition, price, and shipping time for FCM100Et are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Connect the redundant modules to supported 100 Mbps Ethernet paths through the documented splitter/combiners
  • Use 62.5/125 µm multimode fiber with LC connectors
  • Keep each supported optical link between 3 m and 2 km
  • Provide the external time strobe to both FCM100Et modules when required
  • Supply the related ZCP270 pair with the same time-strobe source
  • Validate SOE and TDR/TDA timing after any network or module change
  • Install the modules as an adjacent Master/Tracker pair on the supported baseplate
  • Preserve both Ethernet ports and both Module Fieldbus paths
  • Prove automatic role reversal before returning the grouping to service
  • Redundant ZCP270-to-200 Series FBM communications over 100 Mbps fiber
  • Sequence-of-Events systems requiring externally synchronized FBM time stamps
  • Transient Data Recorder and Transient Data Analysis installations requiring synchronized remote FBMs
Description
FCM100Et is used for redundant communication between ZCP270 control processors and distributed Foxboro FBMs, including synchronized time messaging.

Selection must match the 2 Mbps Module Fieldbus, 100 Mbps fiber network, baseplate slot pairing, power budget and required external time source.

Before replacement, record the active Master/Tracker state, Ethernet fiber connections, HDLC links, FBM inventory and time-source wiring.

Technical notes
FCM100Et is officially styled FCM100Et, with module part number P0926GS. Verify the redundant partner, splitter/combiners, fiber paths, time-strobe wiring and ZCP270 system configuration before replacement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When should FCM100Et be selected instead of FCM100E?
Select it when the documented ZCP270 architecture requires the external time-strobe functions used by SOE or TDR/TDA FBMs; FCM100E does not provide those functions.
Can FCM100Et be installed as a single communications module?
The documented architecture uses a Master/Tracker pair for each FBM grouping, with automatic role reversal and separate optical paths.
Which control architecture is compatible with FCM100Et?
Use it with the documented ZCP270 and The MESH or supported 100 Mbps Ethernet architecture; confirm the installed software and baseplate arrangement before selection.
Are splitter/combiners and fiber cables included with FCM100Et?
No. Treat the module, splitter/combiner pair, LC multimode fiber cables and baseplate as separate items and verify every part against the project bill of materials.
Can one FCM100Et be replaced while the process remains online?
The partner module can maintain communications, but first confirm healthy Master/Tracker status, both network paths and an approved hot-replacement procedure.
Why can SOE or TDR data lose precise timing after an FCM100Et change?
Check the external time strobe to both FCM100Et modules and the ZCP270s, the network type, time-message configuration and active diagnostics.
How should FCM100Et be commissioned after installation?
Verify both Ethernet paths, Master/Tracker role reversal, every assigned FBM, time synchronization and alarm recovery under a controlled procedure.
