AFC for Controllogix
I m having trouble getting my pv's linked into the AFC modules.
Does the AFC module have to be in the local rack or can it be in a remote rack?
I am doing pressure and temperature compensation on a mass meter and can not seem to get the process variables (real) linked into the module. Do they need to be linked up through the modbuss gateway? Which address do i use (9500) for the first input?

RE:AFC for Controllogix
If you look at our sample ladder logic, you will see we have provided Controller Tags for moving all necessary realtime process data to our module.
The main tag of interest would be AFC56.Meters[x].Variables. There are subtags under this tag for each type of meter that allow you to move the process values appropriate for that meter type to the module.
You could use the Modbus Gateway function to move this information to the module; but the included tags work faster and better. Use them instead of the Gateway function.
