FB error: Repeated command of FB discarded since previous job sent was not acknowledged.

Description

A job is to be sent via an FB to the motion controller. The commanded FB sets the “Error” output to TRUE in the same PLC cycle and displays this error message at the “ErrorID” output because the FB is supposed to send a new job but is still busy with a job sent earlier.

Response

Class

-

The job is discarded by the FB and not transferred to the motion controller.

Solution

Class

-

Either wait until the previous job sent is acknowledged by the FB or an FB was commanded to abort the job previously sent.

Afterwards, the FB can be commanded again.

Generally, this case can be prevented if you ensure that a new job is not sent via an FB before a previous job already sent is acknowledged.
