Q03UDECPU I/O refresh time

4 posts in this topic

Dear all,

could someone please explain, I cannot find any setting within Q03UDECPU which sets up how X/Y are being refreshed.

In the manuals I only see that I/Os are refreshed with "scan program". But "scan program" is a freewheeling program, which can't provide fixed scan time and which scan time is usually large (because there are lots of non-time-demanding functions put there), correct?

Can I somehow assign given X/Y refresh time to a "fixed scan program"?

E.g. I have a "fixed scan program" of 10ms, and I on/off Y1 in there and I want that Y1 would be actually refreshed at 10ms base as well. How to do that?

Thank you!

When you use X... this  means de refresh value of the input at the start of a scan. If you want to use the current status of an input than use DX... for instance DX1F Instead of X1F. This means direct Input. 
 
the same applies for the outputs. DY20.
