ABB CM588-CN CANopen Slave Communication Module
CANopen slave connectivity for an ABB AC500 communication-module interface, with defined process-data and network-management services.
Overview
CM588-CN adds a CANopen slave node to a compatible ABB AC500 controller platform. The standard article is intended for normal AC500 system conditions and is distinct from the separately ordered CM588-CN-XC environmental version. Its protocol services support controller-to-network data exchange, configuration and supervision.

Features
- Implements the slave side of a CANopen network for an AC500 controller installation.
- Separates cyclic process exchange from parameter access through PDO and SDO services.
- Supports heartbeat and node-guard mechanisms for network supervision.
- Uses five front indicators for local operating and diagnostic feedback.
- Receives its internal power through the communication-module interface of the terminal base.
Applications
- Connecting an AC500 controller as a subordinate node in an established CANopen machine network.
- Exchanging mapped process values with a supervising CANopen manager.
- Adding CAN-based communication to a supported PM57x, PM58x or PM59x installation.
- Maintaining legacy CANopen architectures that require the exact standard CM588-CN article.
- Service replacement where the original process-data map and node configuration must be retained.
Lifecycle
- ABB identifies article 1SAP172800R0001 in the Active lifecycle phase.
- The standard CM588-CN and CM588-CN-XC have different article numbers and should not be merged in purchasing records.
- Preserve the CANopen node configuration, PDO map and EDS selection before exchanging hardware.
- Check the bus termination and cable arrangement before bringing a replacement node online.
- Validate network state, process data and supervision services after commissioning.
FAQ
Which CANopen role does CM588-CN perform?
It operates as a CANopen slave and must be managed by the network controller or master.
What should be saved before a CM588-CN exchange?
Preserve the node settings, PDO mapping, object parameters and the controller project.
How is the standard module distinguished from CM588-CN-XC?
The XC environmental version carries a separate ABB article number and must be ordered deliberately.
Which service handles parameter access?
The supported SDO server is used for parameter-oriented communication within the CANopen architecture.
What should be inspected if the node remains offline?
Review bus wiring, termination, node configuration and the front diagnostic indicators.
Can the module be treated as a CANopen master?
No. This exact CM588-CN article is the slave module; ABB uses a different product for the master role.
