There are certain tasks that you will want to perform at a specified time or interval or when a change occurs in the process. To schedule these tasks, you will need to define the time or event that triggers the action that you want to occur. The Scheduler is a iFIX application that runs in the foreground or background, monitoring the system and triggering actions based on timers or events. It can be run as a service under Windows, allowing you to log in and out of a Windows node without affecting or triggering scheduled events regardless of whether or not the iFIX WorkSpace is running.
The spreadsheet design of the Scheduler lets you easily create and edit schedules in the configuration environment and view the status and statistics in the run-time environment. It provides you with the ability to create as many schedules as you need to organize your work logically and efficiently, and to run multiple schedules at the same time. Within each schedule you can create as many tasks, known as entries, as you need to run as often as you require. The Scheduler can trigger actions based on five events. These events can use most available data sources as a trigger. Time-based entries are not tied to data sources, and actions are triggered based on a monthly, daily, continuous, or one-shot basis.
Script Authoring Experts are provided for common events, such as opening a picture, running a report, or closing a contact. These Experts prompt you for information pertinent to the operation, generate a Visual Basic script, and tie the script to the appropriate event. For complete information on using the Scheduler, refer to the Scheduler section in the Mastering iFIX manual. For more information on VBA scripting, refer to the Writing Scripts manual.
