[Handshake operation] is a startup method by which completion of job execution
can be notified to a programmable controller CPU.
Handshake operation started
Figure 7.54 [Handshake operation]
When [Handshake startup] turns ON in the sequence program, the MES interface
module collects tag component values used for the job and executes the job.
Upon completion of the job execution, the MES interface module turns ON
[Completion notification].
After confirming that [Completion notification] is ON, turn OFF [Handshake
startup] in the sequence program.
When [Handshake startup] turns OFF, the MES interface module turns OFF
[Completion notification], causing the handshake operation to be completed.
After confirming the completion of the handshake operation, the next job is
executed.
*1 If an error occurs during job execution, [Completion notification] does not turn ON.
To detect such an error, enable [Notify errors (job cancellation) that occur during job execution].
