Counting time

Hello

I am looking for tips on how to count the duration of a given function and then how to display it on the hmi panel in the hh:mm:ss format. For example:how long it took to prepare the cip station or how long it took to clean the cip machine.( My plc s7-1200 and Tia portal V16.)

Thank you all for your suggestions and replies

Do you have defined starting and stopping conditions?

Yes I have.

Something like this?

There are instructions for subtracting time as well, which should make this simpler.



There's also the RTM option, but I think it may be overkill for this.
