ABB CM597-ETH Ethernet TCP/IP Communication Module
A Classic-lifecycle AC500 Ethernet interface with an integrated two-port switch for TCP/IP, UDP/IP and Modbus TCP communication.
Product Overview
CM597-ETH is an Ethernet communication module for supported ABB AC500 processors. Two RJ45 sockets share an integrated switch, allowing a line connection through the module while a netX processor handles the communication interface. The standard article must be distinguished from the separately ordered XC version.
Performance
- Operates at either standard industrial Ethernet copper rate with selectable duplex behavior.
- Uses an integrated switch to maintain traffic between its two RJ45 connections.
- Supports adjustable auto negotiation and a configurable MAC address.
- Provides separate module, status, link and activity indications for commissioning.
- Transfers application data through dedicated dual-port memory to the controller system.

System Integration
- Install the module only with the supported AC500 processor and terminal-base generations.
- Use industrial Ethernet cabling and confirm the address plan before connecting both switched ports.
- Keep the standard and XC articles separate when the installation has extreme environmental requirements.
- Review Modbus TCP connection counts and application timing in the controller project.
- Verify link, activity, address configuration and end-to-end data exchange after service work.
Applications
- Adding switched copper Ethernet communication to a compatible AC500 controller.
- Connecting supervisory and machine devices through TCP/IP or UDP/IP services.
- Serving Modbus TCP clients or servers according to the controller application.
- Maintaining an installed network that specifies the exact CM597-ETH article.
- Lifecycle planning for a Classic module while preserving the proven controller architecture.
FAQ
Does CM597-ETH contain an internal switch?
Yes. Its two RJ45 ports are connected through an integrated two-port switch.
Which lifecycle phase applies to the current standard article?
ABB places CM597-ETH in the Classic phase, so it remains a lifecycle item rather than a new-design recommendation.
Can the two ports be treated as independent CPU interfaces?
No. They belong to the integrated switch and are not equivalent to two independently addressed channels.
Which application protocol is commonly used with this module?
ABB documents Modbus TCP along with TCP/IP and UDP/IP communication functions.
What should be recorded before replacing the module?
Save the IP configuration, application project, connection settings and network topology.
How should link faults be investigated?
Check cabling, port indicators, negotiation settings, switch path and the configured IP network.
