CC%2 Dynamic test ID=%4 aborted: Error in B channel: test ID=%5

¿Qué significa 231-E023 ?

This error occurs during the dynamic test of PLC peripheral devices (PL, MB, UEC) in the Heidenhain TNC CNC Controller. It signifies that the expected signal transition from 0 to 1 on the TEST.B output was not detected. This indicates a problem with the wiring of the TEST.B output, a short circuit, or an incorrect firmware version of the peripheral device, preventing proper safety function verification.

• Incorrect wiring of the TEST.B output, such as an open circuit, loose connection, or wrong termination.
• A short circuit present on the TEST.B output line, preventing the signal from switching correctly.
• Incompatible or incorrect firmware version installed on the PLC peripheral device (PL, MB, UEC).
• A hardware defect within the PLC peripheral device itself, preventing the TEST.B output from functioning correctly.

1. 1

   Check the wiring of the TEST.B output for continuity, correct terminations, and any signs of damage, insulation breakdown, or short circuits.

2. 2

   Verify that the software version of the Heidenhain TNC CNC Controller and the firmware version of the PLC peripheral device are compatible and up-to-date according to Heidenhain documentation.

3. 3

   Perform a software or firmware update on the controller and/or the peripheral device if outdated or incompatible versions are identified.

4. 4

   Isolate the peripheral device if possible and test the TEST.B output's voltage transition using a multimeter; if it remains static, the device may be faulty.

5. 5

   If troubleshooting efforts do not resolve the issue, contact a Heidenhain service agency for further diagnosis or potential replacement of the faulty device.
