ABB’s current product information identifies 57510001-AA as DSCA 114 Communication Board, with the long description specifying asynchronous communication and RS-232/V.24.
An industrial parts catalog also identifies the board’s function as ASYCHRONUS COMMUNICATION and associates it with the ABB SCD-A6 documentation set.
Some third-party listings incorrectly attribute modern interfaces such as Modbus/TCP, RS-485, DIN-rail mounting, or unrelated computer hardware specifications to this part number. Those claims conflict with ABB’s own product description and should not be used for procurement.
Application Scenarios & Pain Points
Legacy serial links can be deceptively difficult to troubleshoot. A controller may remain fully operational while one external device stops responding, leaving technicians to determine whether the problem is the communication board, cable, interface settings, or the connected equipment.
- ABB Advant Master: DSCA114 provides asynchronous RS-232/V.24 communication within the Advant Master process-control environment.
- MasterPiece 200 systems: Parts documentation associates DSCA114 with MasterPiece 200 and 200/1 applications, making it relevant to maintenance of these older ABB control platforms.
- Serial peripheral communication: The board can serve where an installed control architecture requires a dedicated asynchronous serial connection rather than a modern Ethernet-based interface.
- Legacy PLC/DCS replacement: A tested spare becomes particularly useful when the original communication board is discontinued and the plant cannot justify replacing the entire control platform.
Field note: With RS-232 equipment, cable and pinout mistakes are common. A replacement board can be perfectly good and still appear dead if the external device expects a different wiring arrangement or communication configuration.

The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Do not accept generic “communication module” specifications without checking the ABB identification.
The verified ABB description is specifically asynchronous communication, RS-232/V.24.
How to avoid it: Match / 57510001-AA and verify the host system before purchasing. Ignore listings that assign unrelated Ethernet, Modbus/TCP, or S800 I/O specifications to this part.
⚠️ RS-232 wiring is not automatically interchangeable.
Two devices can both be labeled RS-232 while using different pin assignments or DTE/DCE arrangements.
How to avoid it: Record the existing cable termination and pinout before removing the original board. Do not assume a standard DB-style wiring arrangement unless the actual system documentation confirms it.
⚠️ Do not overlook configuration.
Baud rate, parity, stop bits, handshaking, and connected-device settings can make a healthy replacement appear defective.
How to avoid it: Record the existing communication parameters before replacement and verify them after installation. If possible, capture diagnostic information while the original board is still operating.
Frequently Asked Questions (FAQ)
What is ABB 57510001-AA?
ABB 57510001-AA is an asynchronous communication board for ABB legacy control systems. ABB’s product documentation specifies RS-232/V.24 communication.
Is an Ethernet communication module?
No. The verified ABB specification identifies the as an RS-232/V.24 asynchronous communication board. Modern Ethernet or Modbus/TCP specifications found in some listings should not be attributed to this part without supporting ABB documentation.
Which ABB systems use ?
The board is associated with the Advant Master process-control family, and parts documentation also identifies applications involving MasterPiece 200 and 200/1 systems.
What is the difference between and DSCS131?
They serve different communication functions. is an asynchronous RS-232/V.24 communication board, while DSCS131 is identified as a redundant MasterFieldbus communication unit. They should not be treated as functional alternatives.
Can I hot-swap ?
Do not assume hot-swapping is permitted. The safe procedure depends on the specific ABB rack and control-system configuration. Before removing the board, establish whether the installed architecture supports live replacement and determine what process impact loss of the serial link will cause.
How should a used be tested?
A meaningful test should go beyond powering the board:
- Confirm / 57510001-AA identification.
- Inspect connectors and PCB condition.
- Verify correct rack initialization.
- Establish an RS-232/V.24 communication link.
- Test the required baud rate and serial parameters.
- Confirm stable communication with the intended peripheral.
A board that simply powers up is not necessarily a serviceable communication spare.
