Issue Details

I have connected a C Series module to a cDAQ chassis but it is not correctly recognized in Measurement & Automation Explorer (NI MAX). I see the following behavior: 
  • The module is shown with a red X icon
  • The module Settings window shows Status Code: -88705, The specified device is not present or is not active in the system. The device may not be installed on this system, may have been unplugged, or may not be installed correctly. 
  • All other modules connected to the cDAQ chassis are correctly detected and working.
  • This specific module works when connected to another cDAQ chassis.

Solution

In order to troubleshoot the problem, perform the following steps:

Additional Information

For network devices, if the Compact DAQ and its modules have been working before, the Status Code: -88705 can also appear if the PC and the Compact DAQ have not been switched on/off in the correct order. Most importantly: if the PC is switched off, make sure that the Compact DAQ is switched on and connected to the network before switching on the PC. If the Compact DAQ remains disconnected from the network when the PC switches on, the device is not reachable and red cross icons appear next to the chassis and the modules in NI-MAX. To reestablish a connection with the modules, make sure that the Compact DAQ is connected and then reset the device to clear the error.
