Product Details

CM588-CN-XC 1SAP372800R0001 Product Description

The ABB CM588-CN-XC (1SAP372800R0001) is a high-performance CANopen communication module engineered for the AC500 PLC platform, purpose-built to deliver deterministic fieldbus communication across energy-intensive industrial environments. Designed to reduce unnecessary polling overhead and minimize bus latency, this module enables precise coordination between controllers, drives, and field devices — directly contributing to measurable reductions in idle energy consumption and thermal load across the production line.

In modern smart manufacturing, communication efficiency is inseparable from energy efficiency. The CM588-CN-XC bridges the AC500 CPU — such as the PM573-ETH or PM591-ETH — with CANopen-compatible field devices including variable frequency drives, servo amplifiers, distributed I/O nodes, and intelligent sensors. By maintaining tight synchronization across the CANopen network, the module ensures that drive commands, torque references, and status feedback are exchanged with minimal jitter, allowing the control system to execute load-optimized motion profiles and avoid energy-wasting overcurrent events.

Each CM588-CN-XC module supports up to 127 CANopen nodes and operates at configurable baud rates up to 1 Mbit/s, making it suitable for both compact cells and extended production lines. Its compact form factor integrates directly into the AC500 backplane without additional wiring, reducing installation complexity and the associated risk of signal degradation that can lead to unplanned stops and energy spikes during restart cycles.

The CM588-CN-XC is most effective when deployed as the communication backbone of a coordinated energy-control architecture. In a typical smart production cell, the AC500 PM591-ETH CPU executes the main control program while the CM588-CN-XC manages real-time CANopen traffic to downstream devices. Variable frequency drives — such as the ABB ACS580 or ACS880 — receive speed and torque references via CANopen PDO messages, enabling the PLC to implement energy-saving ramp profiles that reduce inrush current during motor start sequences and recover braking energy during deceleration phases.

Servo drives compatible with the CiA DS-402 motion profile, including ABB's MicroFlex e190 series, can be synchronized through the CM588-CN-XC to execute coordinated multi-axis motion with minimal energy waste between axes. The module's NMT (Network Management) master capability allows the AC500 to monitor the operational state of each node — drives, distributed I/O modules such as the TU515 or TU516 terminal units, and intelligent sensors — and to selectively power down or throttle devices during low-demand production windows.

Integration with ABB's CP600 HMI series allows operators to visualize real-time CANopen node status, drive load curves, and energy consumption trends on the shop floor. When paired with a power monitoring module such as the ABB B23 or B24 energy meter connected via Modbus to the AC500, the system can correlate fieldbus activity with actual power draw — enabling data-driven decisions about production scheduling and load shifting. For plants running SCADA platforms such as ABB Ability System 800xA or third-party systems via OPC-UA gateways, the AC500 with CM588-CN-XC provides a reliable data source for energy KPI dashboards and predictive maintenance models.

Uncoordinated fieldbus communication is a hidden source of energy waste in industrial plants. When drives and actuators receive commands with excessive latency or jitter, they compensate by operating at higher torque margins than necessary — consuming more energy and generating additional heat that must be managed by cooling systems. The CM588-CN-XC eliminates this inefficiency by providing a deterministic, low-latency CANopen channel that allows the AC500 to deliver precisely timed commands to every node on the network.

In conveyor and material handling applications, the module enables synchronized speed control across multiple drive nodes, ensuring that belt sections accelerate and decelerate in unison. This eliminates mechanical stress and the associated energy spikes that occur when unsynchronized drives fight against each other. In press and stamping lines, the CM588-CN-XC supports position-synchronized I/O triggering, reducing cycle time variability and allowing the line to operate at its optimal energy-per-part ratio.

Predictive maintenance integration is another key energy benefit. By continuously monitoring CANopen node heartbeat signals and error counters, the AC500 can detect degrading drive performance — such as increasing current draw at a given load point — before it leads to an unplanned stop. Unplanned stops are among the most energy-intensive events in manufacturing, as they require full restart sequences with high inrush currents and extended warm-up periods. The CM588-CN-XC's reliable node monitoring capability helps maintenance teams schedule interventions during planned downtime windows, preserving both energy efficiency and production throughput.

All units are shipped after full functional testing, including CANopen network initialization, NMT state machine verification, and PDO communication validation. Stock is maintained for immediate dispatch, and each module is covered by a 12-Month Warranty against manufacturing defects.

Q1: How does the CM588-CN-XC contribute to energy savings on a production line? By providing deterministic CANopen communication between the AC500 PLC and field devices such as VFDs and servo drives, the CM588-CN-XC enables the controller to deliver precisely timed speed and torque commands. This eliminates the over-torque margins that drives apply when communication is unreliable, directly reducing motor energy consumption and heat generation across the line.

Q2: Which ABB AC500 CPUs are compatible with the CM588-CN-XC? The CM588-CN-XC is designed for the AC500 platform and is compatible with CPU modules including the PM573-ETH, PM591-ETH, and PM595 series. It mounts directly on the AC500 backplane and is configured via ABB Automation Builder, which supports full CANopen network configuration including node addressing, PDO mapping, and baud rate selection.

Q3: Can the CM588-CN-XC replace an older CANopen module in an existing AC500 installation? Yes. The CM588-CN-XC is a direct replacement for earlier AC500 CANopen communication modules. Configuration can be migrated using ABB Automation Builder's import/export tools. It is recommended to verify node address assignments and PDO configurations after replacement and to perform a full network scan to confirm all nodes are recognized before resuming production.

Q4: What is the warranty and testing process for this module? Each CM588-CN-XC unit undergoes pre-shipment functional testing covering CANopen network initialization, NMT master/slave state transitions, and PDO communication integrity. Units are shipped from verified stock and are covered by a 12-Month Warranty against manufacturing defects. Replacement or repair is arranged promptly in the event of a warranty claim, minimizing production downtime.
