Hello everyone, my first thread here. :D

I have some questions about HSC in S7-200. I'm using CPU214 but as far as I saw newer generation of S7-200 works the same way with HSC and use same registers. Anyway what I haven't understand from the manual is can I (and how) access CV to use it's value with some compare instruction.

My application should work something like this: 9 outputs should be turned on during one encoder revolution depending on the encoder position. Encoder has 500 lines. So for example when encoder is between 100 and 120 Q0.0 is on, when between 200 and 250 Q0.1 is on etc. Encoder revolves 1-2 times in 1 second. I think CPU could easily handle that.

Wizard offers CV=PV interrupts which I tried using programing a 9 steps/interrupts but I don't really understand how the whole thing works...

Is there some good manual/text/article/something on HSC-s?

Thanks in advance for your answers.

Thanks for the answers guys. It helped.

Oops, my mistake the operand must be HC1 not HSC1

It confused me for a moment but no problem.

Attached an example, it's in dutch sorry, but have a look at sbr13 there i use things like compare with hsc.

I used a window (venster) where some bits are triggered (between i.e. 500 pulses - or + countvalue.

If you need more help to read the program i can put some comments with it later.

No need for that you've done enough already by uploading it, plus everything is pretty much clear even in dutch.

Anyway I've finished the program in half an hour after I realized the HCx is operand I need.

Thanks again for help.
