I'm using a cFP-2120 controller on a 4-unit backplane housing 3 AI-118 modules and a TC-120 module. Additionally, I'm trying to read data into the serial port (COM 1) of this controller (weather station data). If I run the weather station by itself, it seems to work just fine. When I try to run it with the rest of the software, it acts up, giving lots of communication errors and delays. I have the same code I'm running as a standalone VI running in parallel with the code reading the AI-118 and TC-120 modules. I've done this in the past on a different system and it seemed to work just fine, but this time around I'm not having the same luck. The only difference between then and now is that I ran each as 2 separate VI's running in parallel before whereas now I've got the code in two parallel timed loops in one VI.
Sorry. but I didn't do a thing with priority, as it's not an issue for me. This is a SLOW data acquisition system, with the temperature part (Loop 1)only capable of being read once per second, adn the Data Loop (2) being read onve every 1/2 second.
I did further investigating do to some other "characteristics" of the problem and found a second incident of one of the loops (a separate VI) sitting underneath one of my loops. I deleted it and everything runs fine now. Please forgive me my sudden loss of intelligence.
