#WAIT MC_Status command
The #WAIT MC_Status command makes the system wait for a job acknowledgement. Several events can be specified for job acknowledgements. The command return value can be used to continue program execution.
Available as of V3.1.3110
Syntax of the NC command: |
#WAIT MC_Status [ JobID=.. [MC_NEW] [MC_BUSY] [MC_ACTIVE] [MC_DONE] |
JobID=.. | User-specific JobID/job identification number. Every number must be unique in the commanding program. |
MC_NEW | New job received but not yet processed in the commanded channel. |
MC_BUSY | New job waits for execution in the commanded channel. |
MC_ACTIVE | The job is active in the commanded channel but was not completed. |
MC_DONE | The job was successfully completed in the commanded channel. |
MC_ABORTED | The job was aborted in the commanded channel before completion. |
MC_ERROR | An error occurred while the job is in progress. |
Properties:
- Job IDs are stored in a history when #WAIT MC_Status is called in order to return a correct status in a “later” request even after the job is completed/cancelled. If the job ID specified in JobID is unknown because it was never commanded or is no longer in the history, an error is output.
- The job ID history is deleted at program end. It is therefore no longer possible to synchronise with jobs from previous (client) jobs. It is also not possible to synchronise with jobs from another client.
 | If no expected status is defined for #WAIT MC_Status, an implicit MC_DONE and MC_ABORTED apply. |
