Interfaces & I/O

Two RJ45 Ethernet ports are connected through the integrated switch. The ports support Ethernet TCP/IP, UDP/IP and Modbus TCP communication at up to 100 Mbit/s, enabling controller networking and connection to compatible Ethernet devices.

Selection check

For CM577-ETH, confirm the exact module identity, 2 rj45 ethernet ports with integrated switch, communication rate 100 Mbit/s, station compatibility and applicable installation conditions before purchase.

Installation

Mount CM577-ETH on the supported AC500 station and TH35-15 DIN rail arrangement. Horizontal mounting is standard; vertical mounting requires the specified derating. Provide cable bend radius, strain relief and separation from power wiring.

Selection check

For CM577-ETH, confirm the exact module identity, 2 rj45 ethernet ports with integrated switch, communication rate 100 Mbit/s, station compatibility and applicable installation conditions before purchase.

Operation

Configure network parameters and the required TCP/IP, UDP/IP or Modbus TCP services in the AC500 project. During commissioning, verify link indication, addressing, subnet design, peer configuration and application data exchange.

Selection check

For CM577-ETH, confirm the exact module identity, 2 rj45 ethernet ports with integrated switch, communication rate 100 Mbit/s, station compatibility and applicable installation conditions before purchase.

Compatibility

Confirm the AC500 CPU, engineering software and application protocol requirements before ordering. The exact CM577-ETH model, 24 V DC supply, dual RJ45 interface and Ethernet protocol role must match the planned station.

FAQ

1. How can a buyer verify the exact quoted model?

The quotation, nameplate and packaging must all show CM577-ETH and ABB product ID 1SAP170700R0001. Cross-check the official dimensions 28 × 135 × 62 mm, 2 rj45 ethernet ports with integrated switch and net weight 0.12 kg.

2. How can New, Used and Refurbished condition be distinguished?

Request current photographs of the CM577-ETH label, housing, terminals or ports, seals and packaging. Inspect for mounting marks, connector wear, altered labels or cleaning residue, and require the condition to be stated on the commercial invoice.

3. How can supplier legitimacy and reliability be checked?

Verify the legal company name, registration, business address, bank beneficiary and traceable contact details. Ask for references and a written quotation that identifies CM577-ETH, 1SAP170700R0001, quantity, condition and return terms.

4. Which specifications should an engineer confirm before procurement?

Confirm the AC500 CPU and engineering software support, module position, 2 rj45 ethernet ports with integrated switch, 100 Mbit/s communication, IP20 enclosure requirement, 28 × 135 × 62 mm dimensions and the field network configuration.

5. What physical evidence should be requested before payment?

Request timestamped photographs or video showing the complete CM577-ETH label, ABB product ID 1SAP170700R0001, serial or batch identifiers, connector condition, packaging and all included terminal plugs or accessories.

6. Can a similar model or suffix replace this module?

No automatic substitution should be assumed. A different suffix can change the protocol, controller role, ports, connector or compatibility. Replace CM577-ETH only after the project engineer verifies the alternative against the official ABB documentation and the existing AC500 configuration.
