Product Introduction
The ABB 500CMP04 HE401314/0001 1MRB150051R1 is a legacy ABB 500-series communication-management module. Current industrial parts references identify it as a communication motherboard or Communication Management Processor Module, while ABB-related documentation places the exact part number within the same 500-series hardware family as the 500CPU03, 500PB101, 500CSP04, 500TRM02, and 500BOM01.
The ABB 500CMP04 should therefore be treated as system-level hardware rather than a generic modern PLC communication card. Its purpose is associated with managing internal communication and data exchange within the ABB control architecture. The actual external communication functions depend on the complete system configuration and connected modules.
The ABB 1MRB150051R1 and HE401314/0001 identifiers are important because the 500-series contains several visually and functionally related modules. The closely related 500CSP04 HE401314/0002 1MRB150051R2 is separately identified in the same documentation, so the R1/R2 distinction should not be ignored.
500CMP04
Main Features & Field Considerations
Communication management
The 500CMP04 is identified as a communication-management processor/motherboard, making it part of the system’s internal communication infrastructure rather than a conventional field I/O module.
500-series integration
Its relationship with the 500CPU03, 500PB101, 500CSP04, 500TRM02, and other modules indicates that compatibility must be evaluated at the complete system level.
Revision-specific replacement
Pay particular attention to the complete identification:
- 500CMP04
- HE401314/0001
- 1MRB150051R1
The similar 500CSP04 / HE401314/0002 / 1MRB150051R2 is not automatically interchangeable.
Important Specification Caution
There are conflicting commercial descriptions of this part. One listing calls the 500CMP04 a communication module and assigns 24 VDC, Modbus, PROFIBUS, Ethernet/IP, 100 Mbps, two ports, and DIN-rail mounting; another calls it a communication motherboard; another calls it a communication-management processor.
I would not publish those numerical specifications as confirmed facts for 1MRB150051R1 without the original ABB technical documentation. The available evidence is sufficient to identify the part and its general communication-management role, but not to establish those detailed electrical/interface specifications reliably.
Replacement Checks
Before replacing an ABB 500CMP04, verify:
- Exact model: 500CMP04
- Part number: 1MRB150051R1
- Additional marking:
- Hardware revision
- Installed rack/system
- Associated 500-series CPU
- Communication modules
- Backplane and connector arrangement
- System configuration
- Firmware/application compatibility
If the existing processor is still accessible, record the system configuration and communication parameters before removing the module.
Procurement Note
For ABB 500CMP04 /0001 1MRB150051R1, use all three identifiers in the purchasing specification. ABB-related documentation confirms this exact combination as part of the 500-series family.
For technical documentation or a replacement quotation, I would describe it conservatively as an ABB 500-series Communication Management Processor / Communication Motherboard rather than assigning unsupported modern PLC specifications.
