Scheduler
A scheduler is used to control tags in relation to the real-time clock. This function is used to control events in the process, for example starting and stopping motors, at specific predefined calendar times.
Scheduler Set Up
The scheduler configuration pages are used to set up scheduler jobs, which can include a set of tags with associated start and stop times.
Adding a Scheduler
A scheduler can be added to the project from the Insert ribbon tab.
The scheduler configuration page will open in the desktop when a scheduler function is created or selected.
