Hi Claes,

Thanks

Maybe my question is not exact. I would like to use an analog demultiplexer for analyze of gas.
I have only one device and more gas sources (example: 5).
We have to analyze every source and we have to generate the results as follows.




I could not find a device - an object in the proview - that could be used for \"timer\" (simplifying: astable multivibrator with counter which is shifting the multiplexer)
What object can I use for this function?

Hi Giants,

If you invert the input of a Wait object. and connect the output to the input with a feedback connection, you will get a puls train on the output that you can connect to a Count object.

No problem, it was not polemic at all...

I just said that because It also takes me some time to find some appropriate modules to make some plc prog depending on the name they were given in Proview, their location in libraries or whether the exist or not compared to other softwares I used to use.

As it is stored in a way which is different from this software to others I know (nothing abnormal in this) I thought it could be interested for us to know which modules you use for a particular purpose.

I didn't speak about general information you find in already existing manuals of course.

Regards.
