Each time it runs, it calculates the diference between Actual and last. The last value is the Mw100 but the networ 2 of the sample is rong. Sorry. Here I post the corrected sample. You can do any calculation, to have you speed (pulses / min, pulses/h) if you know how many pulses have a complete turn of the movement or motor. All the best

MOHA06 Posts: 5 Rating: (1)	Hello Gabriel, Thank you for your update. But when I use your sample in my soft I have no value for "%MW1OOO" and when I switch this value by "%ID1OOO" it is working. In the other hand I have another problem: the value "Counter_Per_100_ms" is always equal to 0 0puls/100ms). Should I add some lines in my soft ? Best regards.

But you have to change in the networ 1 and 2. About the other problem, have you configured the HSC0 like the sample? Are you using the correct input?

MOHA06 Posts: 5 Rating: (1)	Hi, It's weird, I also don’t have any value in “IW1000”, but I still have a value in"ID1000" I havewell set theHSC0(HSC1)andthe encoder isconnectedinI0.0. So"LastScanCounterValue"is alwaysat 0. Regards.

You want to use ID1000. Make a copy of ID1000 and save to MD1000. Compare your counts that way. I think that is what Gabriel was intending but we get into the (easy) habit of typing IW and MW instead of less frequent ID & MD references.

Kathyflores Posts: 2 Rating: (0)	Hi, I have the same problem using Step 7 V10.5, I tested your program and the interrupt is never enabled, updating the software would be a very costly solution for the project I am working in. Would you have any suggestion for me to program in the PLC in order to simulate the functioning of an interrupt? I am using the interrups to notify the user of the activation of a smoke and intruders´ alarm in a domotics project for an office in my college. Sincerely, Katherine

Would you have any suggestion for me to program in the PLC in order to simulate the functioning of an interrupt?
