Additional Information
Shared Variables are Not Deployed
If the shared variable library has already been deployed to your host or target computer, you should be able to view it in Distributed Systems Manager for LabVIEW 8.6 or later, or in Variable Manager for LabVIEW 8.5 or earlier.
Programmatically deploying the shared variable library using an invoke node is not supported on real-time targets. However, you can use the invoke node on a host computer and target the real-time target with the "Target IP Address" input option.
Blocked Access from DCOM and/or Firewall
DCOM and/or Firewall settings can prevent your computer from accessing individual variables in the Shared Variable Engine. They can block specific ports that prevents the Shared Variable Engine from using the OPC Server to pass information.
Incorrect Bound Shared Variable Paths
Install the
LabVIEW 8.6.1 Shared Variable Patch if you are using LabVIEW 8.6.1. You will also need to install the patch on target machines running an executable using the LabVIEW 8.6.1 Run-Time Engine.
