ID 270080

Handwheel parameter was not processed by PLC (control unit not empty).

Description

The CNC tries to send the handwheel parameterization data received from another application (e.g. HMI) to the PLC. This data couldn’t be transferred to the PLC via the interface within a defined number of CNC cycles, because the related control unit is occupied by a former order to parametrize handwheel mode.

Response

Class

3

 

Solution

Class

1

The PLC application has to be checked, to be sure that

  1. the request semaphore of the control unit is set to FALSE after each transfer of parametrization data into the PLC.
  2. the PLC cyclical checks, if there are new parametrization data in the control unit.
  3. if you don’t want to handle handwheel parametrization by the PLC the enable flag of the concerning control unit is set to FALSE.
