How do I see the value of the timer

Please also see the screenshot.

I need to modify the conditions opening and closing a lid and in that logic a the value from a timer is used (#Timer_04.Q).

Where can I see the when it will be set and what is setting it?

Hello,

Timer preset time is of 5 Second, it starts counting time when signal at IN changes to 1, & after preset time i.e. 5 second output signal ENO will change to 1.

Thank you for answering gentlemen.

I did not formulate my question well enough - and in this case it was the last answer almost gives me the answers I am looking for.

What is the advantage of using this "model" of timer instaed of dragging in a "S_ODT" timer in from the timers folder (there is predefined 25 times in the block interface and only the first 4 are used)?

Just to mention few:

+ no worries about using the same timer more than once - no need to keep track of xref

+ easier to reuse a code - no need to renumber the timers

+ no worries about running out of available timers

+ handling of TIME is much easier than S5Time

Hello,

PT - instruction Load time duration sets the duration of timer. The instruction is executed in every cycle signal at IN input of the instruction has the signal state 1. The instruction writes the specified time to the structure of the specified timer.

The instruction data is updated only when the instruction is called and not each time the assigned timer is accessed. So in your case, when signal at IN is 1, output ENO will be 1 for 5 sec & after it will be 0 irrespective of signal state at IN. It is pulse timer & not ON delay timer.

"SIMATIC Timers" versus "IEC Timers"
