ID 270082

Rapid mode key press was not processed by PLC (control unit not empty).

Description

The CNC wants to pass on the data to the PLC after the press of a rapid traverse button in another application (e.g. HMI) and write it to the PLC interface. However, this data could not be written to the corresponding Control Unit of the interface to the PLC within a defined number of CNC cycles, because this Control Unit is still occupied by previously transmitted data.

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 data concerning a pressed rapid key into the PLC.
  2. the PLC cyclical checks, if there are new data concerning a pressed rapid key in the control unit.
  3. if you don’t want to handle rapid key by the PLC, the enable flag of the concerning control is set to FALSE.
