More Information

Overview Manuals Mixed Fieldbus Twinax Cabling Migration Application
  • Filter mixed-rate FCP270 traffic so 100 Series devices receive only 268 kbps messages
  • Isolate and extend the legacy twinaxial Fieldbus to remote 100 Series hardware
  • Preserve the A/B baseplate, terminators and remote FBI topology during replacement

FBI100 is a Foxboro fieldbus isolator/filter for 100 series fbms designed for the Foxboro Fieldbus Isolator/Filter Modules family.

Foxboro FBI100 filters FCP270 fieldbus traffic so legacy 100 Series FBMs receive their 268 kbps messages while remaining galvanically isolated from the 2 Mbps segment. FBI100 is the functional designation and P0923LN is the module part number; P0923LR is the separate two-slot vertical baseplate.

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 FBI100 are confirmed during quotation.

  • Accept the mixed 268 kbps and 2 Mbps HDLC traffic from the FCP270 side
  • Block 2 Mbps messages from the connected 100 Series Fieldbus
  • Keep all 100 Series device counts within the FCP270 sizing limits
  • Use the documented P0923LR vertical baseplate for the A/B module pair
  • Maintain the remote 268 kbps path over approved twinaxial cable
  • Terminate the first and last points of each Fieldbus chain as documented
  • Support 100 Series DIN-rail FBMs on the isolated 268 kbps Fieldbus
  • Connect listed SPECTRUM and Fieldbus Cluster I/O hardware
  • Use only documented Honeywell, Bailey or Fisher PROVOX migration interfaces
  • FCP270 systems retaining remote 100 Series FBMs on a 268 kbps Fieldbus
  • Mixed FCP270 installations containing both 200 Series and legacy 100 Series FBMs
  • Supported SPECTRUM, Fieldbus Cluster I/O and competitive migration interfaces
Description
FBI100 isolates and filters an FCP270 fieldbus so legacy 100 Series FBMs receive 268 kbps HDLC communications.

Selection must match module part P0923LN, the P0923LR two-slot vertical baseplate, controller sizing and the documented twinax cable limits.

Before replacement, record the A/B module positions, baseplate, cable lengths, termination, connected FBMs and current fault indications.

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 FBI100 be selected instead of FBI200?
Use FBI100 in the documented FCP270 path for filtering and extending the 268 kbps 100 Series Fieldbus; select FBI200 when its 2 Mbps extension or upgrade functions are required.
Can FBI100 be connected directly to an FCP280?
The FBI100 product specification defines its use with FCP270. Do not transfer FBI200 or FCP280 topology rules to this model.
Are the baseplate and fieldbus terminators included with FBI100?
No. The P0923LR baseplate, P0916RB or project-specified terminators, twinaxial cabling and remote FBI hardware are separate items.
Why can 200 Series FBMs work while devices behind FBI100 remain offline?
Check the 268 kbps A/B outputs, twinax polarity and continuity, remote FBI termination, baseplate power and the configured 100 Series device addresses.
Can one FBI100 be replaced without powering down the baseplate?
Yes, the module can be removed from its baseplate with power present, but first confirm which A/B path is carrying traffic and follow the approved procedure.
What must be preserved before replacing FBI100?
Record the A/B module positions, P0923LR baseplate, FCP270 cable, both twinax routes, remote FBI chain, terminators, device count and active diagnostics.
How should FBI100 be commissioned after installation?
Verify filtering on both buses, confirm every 100 Series or migration device, inspect traffic LEDs and prove communication recovery after a controlled A/B path test.
