I am using the Timer object in my PLC program to delay a signal. Currently I have defined a fixed TimerTime but this should be configurable without changing the PLC program. Can the TimerTime parameter be set at RunTime in some way?

Otherwise I would probably use a CArithm object with some simple C-code.

Hi Ondrej,

Yes, you can set the TimerTime in runtime, for example from the plc-code with a StoAp or CStoAp.

Changing the TimerTime to a timer-object won't take effect for an active timer-object (one that is already counting). It will take effect first when the timer is retriggered.

Hi Claes and Robert,

this works perfectly.

Thanks for your help, Ondrej

Now I ran into another problem.

In some cases I need to stop/reset (not restart) the timer. This doesn't seem possible. Is there some other object I could use instead?

Ondrej

I guess you could play with the internal attributes of the timer object (timercount and timerflag). The best way though is to put some logic after the timer object that makes the job for you.
