I have a cRIO 9076 with two NI 9265 modules, one NI 9207 module and one NI 9482 module. I am having an issue with the analog output from my NI 9265 module. I am using it to control air actuating ball valves and it works fine except when I go to open the ball valves by more than 30%, say from 60% closed to 30% closed. When this happens the module seems to lose contact with that channel. It becomes unresponsive to my inputs and I am no longer able to control that ball valve. If I restart the system it regains contact with the channel and is able to perform normally until I try to open the ball valves by at least 30% again. There are also quick disconnects for the ball valves and if I disconnect this and then reconnect it, it goes back to performing normally. I am not sure if there is a setting that I could change that would fix this problem? I have a cFP system that performs the same operation and it is easily able to handle this type of action. Any ideas? Thanks for your help.
The 9265 requires an external power supply - do you have one connected?
How many channels on the 9265 are you using?
Also what version of LabVIEW and NI-RIO are you working with? Are you using the chassis in Scan Engine mode or FPGA mode?
