Can I Access a C Series Module From Two Programs at the Same Time ?

Hardware

  • cDAQ-9189

Software

  • LabVIEW
  • VeriStand

Issue Details

  • I am using a cDAQ chassis with a C Series Module. I would like to acquire data from one channel with LabVIEW, and from another channel with VeriStand. 
  • I have two LabVIEW executables and a cDAQ chassis with a C Series Module. I would like to acquire data from one channel with one of the executables, and from another channel with the other executable.

Solution

It is not possible to use two software or executables at the same time to acquire data from channels on the same module. The module will be reserved by the first program used and an error message will appear on the second. The error message is the following : 

 

The specified resource is reserved. The operation could not be performed as specified. 

Additional Information

It is possible to use two different programs to acquire data from two channels on distinct modules. When reserving the resource, the software only reserves the module and not the chassis. Other modules are still accessible by a second software.
