cDAQ-9189 with Ethernet interface

[Jumayev]

Hello,

we are using the latest DAQmx SDK, v17.6 (ANSI C codes) for the integration of the cDAQ-9189 Chassis/NI 9215(A) in our tool. The  cDAQ-9189 Chassis uses Ethernet Interface to PC.  Currently we a facing some strange issue while starting the Task (DAQmxStartTask) giving the error Output "Retrieving properties from the network device failed. Make sure the device is connected". This is output is not true as we can see that the NI Cards are still accessable via the "NI MAX" tool and this happens only with Ethernet Interface. Our module should be correctly implemented as it is working with other NI cards via the USB Interface. Do you have any idea why it is happining and could you suggest any solution please?

Just additional information: in our tool, there is a MATLAB Simulink model also integrated, which should be completely independent on the NI module, are they share some resources(.dlls) and could it be reason?

Thanks!

Try running this code in your ini before you try talking to anything else.

It tests to make sure the chassis is connected and reserves it automatically before moving on. It will throw message so you can see what is going on. You will need to change the device to the one you are trying to connect to.
