[sudanee]

Hi
I am looking for function to calculate runtime for motor, signal ..... in specific period of time
for CPU 300

thanx

insert this source code as a stl source and compile. It will generate FB31. You should call FB31 in any cyclic OB. IF you use OB35 (OB default cycle time is 100 msn) WORK_TIME:=100.0

thank you FLiMBO
I will check and give feedback

[sudanee]

work like a charm
simple and perfect

I appreciate your help

Be aware of danger to use one-stage totalizing algorithm like this FB31!

Hello,
another way to measure time is shown here:

for TIA V11

and here for step7 v5.5
