⚠️ Quick Fix for ABB Error 37002
If this error appears, try these immediate actions:
Quick checks often resolve temporary slave communication faults.
ABB Robot Error 37002 – Fieldbus Slave Communication Fault occurs when the ABB IRC5 Controller detects a failure in communication with one or more slave devices on the Fieldbus network.
Error 37002 indicates that one or more Fieldbus slave modules are unresponsive, misconfigured, or reporting communication errors, preventing normal operation of connected I/O devices.
Affected areas may include:
Broken, loose, or improperly connected Fieldbus cables (Profibus, Profinet, EtherCAT) can interrupt communication between master and slave devices.
Common issues include:
Using high-quality Fieldbus cables and maintaining proper routing improves network reliability and prevents intermittent slave communication failures.
Communication failures often originate from damaged or failing DSQC Fieldbus slave modules inside the controller.
Common issues include:
Replacing faulty DSQC slave modules with reliable, tested units restores stable communication with connected I/O devices and ensures uninterrupted robot operation.
Slave devices not properly mapped or configured in the controller can generate errors.
Outdated RobotWare or Fieldbus firmware may cause incompatibilities.
Sudden power loss during configuration updates may corrupt slave module settings.
Replacement is recommended if:
Persistent slave module faults may require hardware replacement or firmware support:

ABB Robot Error 37002 – Fieldbus Slave Communication Fault indicates a problem with communication between the controller and Fieldbus slave devices. Common causes include damaged cables, faulty slave modules, configuration errors, and firmware incompatibilities.
By inspecting modules, verifying connections, and restoring controller configuration, engineers can restore reliable Fieldbus communication and normal robot operation.
Typically caused by loose/damaged Fieldbus cables, faulty slave modules, incorrect configuration, or firmware issues.
Restart the controller, inspect slave modules and cables, verify configuration, and update firmware.
Yes, new slave modules may require correct mapping and configuration in the controller.
Replace slave modules or cables if errors persist after inspection and configuration restoration.
