01 / PRODUCT OVERVIEW
A Dedicated Interface for Fieldbus Communication

The Foxboro FBM222 P0926TL provides an interface between PROFIBUS-DP/PA slave devices and the I/A Series system. It supports two galvanically isolated PROFIBUS channels and can operate as a single module or as part of a redundant pair. The design supports PROFIBUS-DP Class 1 and Class 2 masters, including multi-master configurations.

03 / REDUNDANT OPERATION
Two Roles. One Coordinated Pair.
Designed to support continuity in field communication

↻ Automatic Role Transition
If the Master module experiences an operating fault, the redundant pair automatically changes roles. The specified transition is designed to occur without loss of data updates.
A redundant configuration may include redundant termination assemblies, hot-swappable modules and fault-tolerant control processors, depending on the installed system arrangement.

1,500 kbit/s 200 m
3,000 / 6,000 / 12,000 kbit/s 100 m
⌁ Network Planning Note
Actual limits depend on cable characteristics, topology, repeater placement and selected communication rate. Confirm the complete bus layout before commissioning.
05 / FREQUENTLY ASKED QUESTIONS
Technical FAQ

❔ Q1. How many PROFIBUS devices can FBM222 P0926TL support?
↳ A: A non-expanded segment supports up to 31 slaves. With repeaters and an appropriately expanded network, the module supports up to 125 slaves per port. Final capacity depends on the complete bus design.
❔ Q2. What happens if the Master module in an FBM222 P0926TL redundant pair fails?
↳ A: The Master and Tracker modules automatically change roles when the Master experiences an operating fault. The specified transition is designed to occur without loss of data updates.
❔ Q3. Can FBM222 P0926TL connect PROFIBUS-PA field devices?
↳ A: FBM222 provides an interface for PROFIBUS-DP/PA slave devices within the I/A Series architecture. PROFIBUS-PA devices generally require a suitable DP/PA link or segment coupler. Confirm the field-network arrangement before connection.
❔ Q4. Why do baud rate and repeater placement matter for FBM222 P0926TL?
↳ A: PROFIBUS segment length decreases as baud rate increases. For example, the stated maximum is 1,200 m at rates up to 93.75 kbit/s, compared with 100 m at 3,000–12,000 kbit/s. Repeaters can extend the network architecture and device capacity.
❔ Q5. Can FBM222 P0926TL be replaced without disconnecting field wiring?
↳ A: The module is designed to be removed or replaced without removing field-device termination, power or communication cabling. Follow the site's approved replacement procedure and confirm the installed redundancy arrangement before service.
