Hello all. Doing my first project on Controllogix platform, and have a question. When I set up a PID on this and toggle the .SWM parameter, I am sending an output (0-100%) speed from a panelview to the PID instruction .SO parameter. The PID CV is scaled 0-60 in order to send a speed reference to a drive in HZ. So when I switch to software manual, is the CV still scaled 0-60 just the same as if the PID was running in auto? I have limited time to test this on a running system.
 
I was able to locate a running compactlogix and go online and test it out. Worked as I anticipated. I can't imagine there is much difference between the two platforms.
