Timer Source System

A timer is a configuration element that changes its value periodically at specified times.

You can use timers to trigger actions using PCo at configurable, usually periodic, times. You can use the timer source system, for example, for the following tasks:

You want to record a reading from a machine at fixed, regular intervals in order to store a time series of measurement data for documentation purposes.
You want to automatically trigger a cleaning operation in a production plant at a specific time in the week after the end of the shift.
You can set up a periodic automatic data backup using the timer source system and an implementation of enhanced notification processing delivered by SAP. (See also: Setting Up an Automatic Backup.)

You can maintain one or multiple timers and their schedules in a timer source system.

If you create an agent instance for a timer source system, you can generate subscription items there for the configured timers. When the timer values change, notification messages are triggered and these can be used to call up any destination system, for example, a simulation destination system or a multiple call destination system. You need to configure any further actions in the multiple call destination system. (See also: Create Timers and Trigger Notification Messages.)

The following tabs are available for configuring the timer source system:
