Timers

Timer channels play a crucial role in various aspects of commissioning, configuration, operation and monitoring of processes. They are essential for scheduling tasks or events at specific times, setting timeouts for particular actions or conditions and measuring time intervals between events.

Within EPM Data Management up to 128 Timer channels can be configured.

Note - The current value of a Timer is stored as non-volatile (NVOL) data and is saved to the EPM Device on-board memory. Historical data for the channel is saved as part of the .uhh recording.

Timer channels can be used to:

  • Provide timing capability

  • Create delays or pauses in program execution

  • Automate routine maintenance tasks

  • Schedule backups

  • Schedule data updates

All of which help ensure processes run smoothly and efficiently.

Timers can be:

  • Singular occurrence - Initiated either manually or via a Job from the operator panel, providing they have the appropriate permissions, see Using the Timers Operator Panel for details.

  • Repeating - Initiated either manually or automatically based on configured Jobs, see Configuring Jobs for details.

Note - Timers do not adjusted for daylight saving changes. Any timer set to trigger on a time frame, such as days or weeks, occur with an hour delay during 'Summer Time', for example, a timer instead of midnight it would trigger at 1am (01:00).

The following Timer types are available:
