NC-PMC I/F ASSIGNMENT ERROR

What does ER54 mean?

This PMC alarm signifies an interface assignment error between the NC and the PMC. It is triggered when duplicate numbers are detected within the PMC assignment parameters, which prevents all Programmable Machine Controllers (PMCs) from starting due to conflicting address allocations.

• Assignment error in the NC-PMC interface.
• Incorrect mapping of I/O signals between NC and PMC.
• Communication issue between the numerical controller and programmable machine controller.
• Conflicting I/O assignments in the system configuration.

Click steps to track your progress.

1. 1

   Identify the parameters responsible for NC-PMC interface assignment (e.g., specific PMC address allocation parameters).

2. 2

   Check all identified PMC assignment parameters to ensure that no duplicate numbers are set across them.

3. 3

   Verify that each PMC address is uniquely allocated and correctly specified in its corresponding parameter.

4. 4

   After correcting any duplicate assignments, turn the CNC power off and then back on to apply the changes and reinitialize the PMCs.
