xltek : you must first understand a few things ...
1. Timers are NOT timers.
They are just instructions which when they execute, do a comparison between the PLC clock, and a stored value hidden inside the timer data.
The timer accumulator is then updated with how much real-time has elapsed since the timer instruction was last executed.
Then the instruction checks to see if the Accumulator value (.ACC) is greater than or equal to the Preset (.PRE).
If it is, then the instruction sets the .DN bit, and turns off the .TT bit.
2. So, because of 1. above, timers will only give the appearance that they are working if the rung on which they sit actually gets scanned by the processor at regular intervals.
3. The code in event tasks only executes when the event occurs, once only (per event). After it has executed this once, it doesn't continue to function, so your timer will not update until the next event triggers the event task.
4. An Event Task is "most often" triggered by an external event, such as a specific input bit or pattern occurring, or a data-change of a consumed tag (tag data from another processor).
Summary :...
Using the EVENT instruction in your normal, continuous task is very similar to just conditionally executing a subroutine with the JSR instruction.
If you give more explanation of what you are trying to achieve, we can advise further.
