The ABB CM588-CN communication module (Order Code: 1SAP172800R0001) is an advanced fieldbus interface module designed specifically for the ABB AC500 series of programmable logic controllers (PLCs). This model is particularly engineered to support CANopen communication, allowing seamless integration between the PLC and a wide array of CANopen-enabled field devices such as I/O units, motor controllers, encoders, and sensors.

As an integral component in modern industrial networks, the CM588-CN provides deterministic data exchange, precise device coordination, and simplified diagnostics—all essential for robust control in distributed automation systems. Thanks to ABB’s Automation Builder software, the module can be easily configured and managed, ensuring efficient commissioning and maintenance workflows.

The module is housed in a compact DIN-rail-mounted enclosure, making it suitable for tight industrial control cabinets. Its support for master functionality allows it to control multiple CANopen devices within a single network, expanding the flexibility and scalability of automation projects.
