Thanks everyone. I am going to the panel tomorrow, and will change the program to the values to 0-16383, SPS to 7372 (9GPM on a 0-20GPM scale 45%)and get rid of the add block. After that it will just be adjusting my gains to get the results I need. I will read up on some techniques to do this before I go. I will keep everyone posted.

Everyone thanks for replying. I do have all of my JSR commands in Main2, I just deleted all of the other logic for file size considerations. At first I tried running the straight PID, with my needed 9GPM setpoint level, and had no output from my PID. So I added to the value that represents my 9GPM, thinking that my PID would only output the needed correction factor. I was told to have my input represent my flowmeter range, but it being only a 0-20GPM transmitter, I wanted more resolution than that. I tried using a float, but the PID didn't like that. If you have any other questions that mighy help you figure out what I am doing wrong, please ask.

Can anyone help me with my PID issues, I can't seem to get them to work. The 3276 - 16383 represents the 4 - 20 mA scale. The 3153 - 15365 represents the actual values of a 4 - 20mA signal injected into the input. The 8761 represents the 9GPM required flow. Any help would be appreciated.
