We use one FP-1601, one TC-120, three AI-110, one DO-401, and one CTR-502 for our real-time data sampling systems. We found that the numbers and figures could not be shown (updated) on the front panel. But the Max was able to show all the correct measurements (Volts, Amps and Counts). Also, we found that the measurements from those modules can not be read by the code but the code can control the DO-401 very well. So anybody tell me why and how to fix it? Is it an iak file problem? Thanks!
Fred
