I am programming a system that will have a 4-20mA linear position sensor that will go from 4-20mA then 20-4mA in one full cycle. This cycle will continuously repeat itself at a set speed. Next, I have an identical hardware setup that I need to lag behind or follow the first cycle at roughly 30% of the cycle. It will be controlled by an analog output signal. I have had several ideas of how to do this that would work as the leading value is increasing from 4-20mA but I am running into a roadblock of how to get the second value to continue to increase to 20mA and then follow the leading value back to 4mA. I am programming in RSLogix 5000. Any help or ideas would be greatly appreciated!
