# ID 270079

Incremental jog parameterization request was not processed by PLC (Control Unit occupied).
Description | The CNC tries to send to the PLC the incremental jog mode data received from another application (e.g. HMI). However, this data could not be transmitted to the PLC via the interface within a defined number of CNC cycles, because the associated control unit is still occupied by a previously transmitted job for parameterization.
Response | Class | 3 |
Solution | Class | 1 | The PLC application has to be checked, to be sure that

1. the request semaphore is reset by the PLC in the control unit after each extraction of parameterisation data.
2. The
3. if the PLC is not to handle a parameterization request for incremental jog mode, the Enableflag of the corresponding Control Unit is set to FALSE.

Parameter | %1: |
Number of CNC cycles in which the CNC tried to write the data into the interface to the PLC.
%2: |
