# ID 270079

Incremental jog parameter was not processed by PLC (control unit not empty).
Description | The CNC attempts 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 parameterisation.
Response | Class | 3 |
Solution | Class | 1 | The PLC application must be checked immediately to ensure that

1. the request semaphore is reset by the PLC in the control unit after each extraction of parameterisation data.
2. the PLC checks the control unit for new parameter data received.
3. if the PLC is not to handle a parameterisation job for incremental jog mode, the Enable flag of the corresponding Control Unit is set to FALSE.
