Timer Status

Introduction

Certain tag types do actions on a timed interval. For example:

The PLC Device Tag will poll the status of a PLC at a predefined interval.
The Calculated Analog tag will calculate the value of an expression at a predefined interval.

The status of timed activities is stored in a TimerStatus property. The TimerStatus property consists of three fields:

Property	Type	Version	Description
EventCount	UDINT	2.4	The number of times this timer has run.
MissedEvents	TIME	2.4	The number of executions that were skipped because the chosen interval was too small.
NextEventTime	DATE_AND_TIME	2.4	The timestamp of the next execution.
