ABB product listings identify DSCS131 / 57310001-LM as a MasterFieldbus Communication Unit with Redundancy. The published ABB product dimensions are approximately 321.3 × 19.8 mm, with a net weight of 0.46 kg.
The same part number is independently cataloged as an ABB Communications Module for the Advant/OCS control platform.
Application Scenarios & Pain Points
When a legacy DCS communication path starts dropping stations, replacing an I/O card immediately can be the wrong move. The real problem may be farther upstream at the fieldbus communication layer.
- ABB Advant Master systems: DSCS131 provides MasterFieldbus communication within the Advant control architecture.
- Redundant communication architectures: The unit is specifically described as having redundancy, making it relevant to systems where communication continuity is part of the control design.
- Remote I/O communication: Where configured accordingly, the MasterFieldbus layer provides the communication path between control hardware and field-level stations.
- Legacy DCS replacement: A tested DSCS131 is useful when an existing Advant installation remains operational but an original communication board has become unreliable or difficult to maintain.
Field note: If one remote station disappears while others remain healthy, inspect the fieldbus segment, termination, addressing/configuration, and station power before condemning the DSCS131. If an entire communication branch fails at once, the module or its associated interface deserves much closer attention.

The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Do not replace based only on connector compatibility.
The board belongs to a specific ABB Advant Master/Advant OCS communication architecture. A physically similar card can have a completely different bus function.
How to avoid it: Match + 57310001-LM, system generation, rack location, hardware revision, and the cabinet’s communication drawings.
⚠️ Do not assume a fieldbus fault means the communication board has failed.
A broken fieldbus cable, incorrect termination, station power loss, or configuration problem can produce very similar symptoms.
How to avoid it: Check the communication diagnostics and segment health first. If the fault follows the communication board after controlled substitution, the diagnosis becomes much stronger.
⚠️ Be careful with redundant configurations.
is specifically described as a redundant MasterFieldbus communication unit. Replacing one side of a redundant arrangement without understanding the active/standby configuration can turn a recoverable fault into a larger communication outage.
How to avoid it: Record active/standby status, LED indications, cable connections, and diagnostic information before removing the module.
Frequently Asked Questions (FAQ)
What is ABB 57310001-LM?
ABB 57310001-LM is a MasterFieldbus Communication Unit with redundancy used within ABB’s Advant Master control-system architecture.
Is an I/O module?
No. It is a communication module, not a conventional analog or digital I/O card. Its job is to provide the MasterFieldbus communication layer connecting the control system with field-level equipment.
Does support redundant communication?
Yes. The ABB product description identifies the specifically as a MasterFieldbus Communication Unit with Redundancy.
What systems use ABB ?
The part is associated with the ABB Advant Master / Advant OCS control-system family. Exact compatibility should still be verified against the installed controller and cabinet configuration before procurement.
What are the physical dimensions of ?
Published product information gives approximately 321.3 mm wide × 19.8 mm high, with a stated net weight of 0.46 kg.
How should a used be tested?
A visual inspection is not enough. For a critical spare, testing should verify:
- Correct board identification and hardware revision.
- Rack initialization.
- MasterFieldbus communication.
- Redundant-channel behavior where applicable.
- Diagnostic/LED status.
- Stable communication under sustained operation.
A board that simply powers up on a bench has not necessarily been proven as a good DCS communication spare.
