Activation job for manual operation mode was not processed by PLC (control unit not empty).

Description

The CNC tries to forward a job from another application (e.g. HMI) to the PLC. The order contains data which input device (e. g. key, handwheel) commands a specific axis in manual operation mode .

This job to assign an input device to an axis, however, could not be written within a defined number of CNC cycles via the associated control unit of the interface to the PLC, because this control unit is still occupied by a previously transmitted data.

Check the following points in the PLC application:

1. In the Control Unit, the request semaphore must be reset by the PLC after each acceptance of data from an activation request for manual operation mode.
2. The PLC cyclically checks the Control Unit for newly received data.
3. If the PLC is not to handle an activation request for manual operation mode, the Enable flag of the corresponding Control Unit is set to False.
