Really I been looking for some sample ladder to see how it's done and go from there.
The scope of the project is to control 2 pumps and 2 heaters on my single tier Hermes system. The firm ware isn't there yet but eventually I'd like to use the web server function with WinCC on a laptop to act as a virtual HMI.
Problem right now is I just haven't hit the critical mass of Siemens knowledge to pull this off just yet.
I speak ancient Japanese, not new age German!
dtfeld said:The biggest issue right now is how to input the setpoint for the PID. The PID element sets up a database but I can't find a way to just drop a value into it.
I think there must be a data move function but I have been unable to find or understand how that's done
