6.1.4 Trigger monitoring function
The trigger monitoring function monitors values such as the time and tag values and, when
the trigger condition changes from false to true (when the condition is met), starts a job.
The following setting options are available as conditions for start.
• [Disable]: Does not start the job by a trigger condition.
• [Time specification startup]: Starts the job at the specified time.
• [Specified time period startup]: Starts the job at the specified intervals (Unit:
Seconds).
• [Value monitoring startup]:
Compares the actual tag component value with the condition value (tag component
value or constant value) at every sampling times, and starts the job when the
condition is met.
• [Handshake operation]:
Starts the job on request from the programmable controller CPU.
Completion of job execution can be reported to the programmable controller CPU.
• [At module startup]:
Starts the job only once when the MES interface module starts up.
Two kinds of conditions can be used in combination for starting a job.
For the trigger monitoring function setting, refer to the following:
