CM572-DP communication module: PROFIBUS role, CPU support and bus commissioning

CM572-DP adds PROFIBUS DP master communication to an ABB AC500 controller. ABB documentation identifies V0/V1 protocol support and transmission rates up to 12 Mbit/s. The module mounts beside the CPU on the terminal base and communicates across the coupler interface. Compatibility is tied to the CPU generation, terminal base and project engineering environment; confirm each before procurement.

Key technical data

The values above are intended to identify the listed version and support an initial technical review. Confirm applicable standards, rating conditions, installed accessories and the current ABB documentation for the serial number or revision before design approval, replacement or commissioning.

Application and engineering focus

Map the planned PROFIBUS network role, node count, baud rate, address plan, GSD files and scan-cycle requirements. Validate that the processor and engineering software support the intended master configuration. Check bus cable type, segment length, repeaters, termination and electromagnetic environment. A communication module does not guarantee interoperability until device descriptions, parameterization and application logic have been validated.

Configuration, compatibility and related references

ABB hardware data names supported CPU families and TB5xx terminal bases, but the precise combination must be confirmed for the installed generation. Inspect the order code and firmware revision and check the lifecycle status before planning new installations. Related CM modules use different fieldbus protocols and connectors; a similar housing or shared base does not make them functionally equivalent.

The related designations below are comparison references, not automatic substitutes. Confirm the complete type code, order number, interface, ratings and revision against the approved application before selecting an alternative.

No additional exact same-series designation is shown here. Confirm the full ordered configuration before selecting a replacement.

Installation and commissioning checks

De-energize the controller assembly and use anti-static handling procedures unless the exact hardware documentation explicitly permits another method. Seat the module on the intended terminal base, secure the bus connector and route the cable with proper shielding and strain relief. Commission by checking module status LEDs, bus diagnostics, address assignments and each slave’s data map, then test communication-loss behavior in a safe state.

During commissioning, verify the nameplate, configuration, wiring and diagnostics before enabling normal operation. Test the relevant signal path or protection response end to end under controlled conditions. Record settings and as-left measurements, and investigate abnormal values at the sensor, load, wiring or system configuration before replacing components.

Ordering, replacement and application information

For a quotation or replacement review, provide the complete designation 1SAP170200R0001, CM572-DP, ABB order code where available, serial or hardware revision, quantity, installation environment, connected equipment, interface requirements and target delivery date. Include a clear rating-label photograph and relevant wiring, loop or panel drawing when possible.

Ask the supplier to confirm the exact configuration, accessories, revision and any approved successor in writing. Do not select solely from a family name or product photograph. For safety, grid-protection, medium-voltage or regulated applications, obtain review by the responsible qualified engineer and follow local codes and the manufacturer’s instructions.
