Control 2 way valves with IDF_2
I had a problem using IDF_2 to control 2 way valves. I want to force OU1/OU0 to FALSE when end position is reached (FB1/FB0 = TRUE), in AUTO and MANUAL and LOCAL mode. Each valve has 5 variables FB1, FB0, OU1, OU0, LOC. How can I do that?

Hi,
Disabling the Tracking when LOC=TRUE is not possible.
The only way I see is to not use the LOC input pin at all and to use some external logic (UFB?).
How do you force OU to FALSE in AUTO and MAN? With PR1 =TRUE and PR0=TRUE?
Do you need the LOCAL mode information for something?
Sorry, more questions than answers...
Regards
Jürgen

Which mode doesn't work as expected? Local?

Yes. I don't want OU1 / OU0 = FB1 / FB0 in LOCAL mode.
