Issue Details

I am currently trying to run or deploy a code which has the NI IEC 61850 VIs in the form of an installer or executable on my Windows System. It works perfectly in the normal (on windows) VI mode. However, whenever I run this installer/executable, I get an error saying:
LabVIEW: Resource not found. nii61850clvapi.dll. An error occurred loading VI’61850C.lvlib: Read IO Handler (Bool).vi

Solution

The NI-IndCom for IEC 61850 software driver is a set of LabVIEW functions used to create IEC 61850 outstation or client applications. You can program these functions on Windows computers for development and debugging and then deploy them on NI real-time controllers such as CompactRIO, Single-Board RIO, and PXI for field applications. This protocol runs over TCP/IP networks.

While deploying the code as an Installer/Executable, make sure that the target system is an LabVIEW RT (Real Time) based system not a Windows system or target.

Additional Information

The error occurs due to the following reasons:
  • The VIs and properties in the NI-Industrial Communications for IEC 61850 software is used only for prototyping and system debugging, in a Windows environment.
  • For deploying your IEC 61850 applications to NI CompactRIO controllers or to NI PXI controllers, which have RT OS in it.
  • The NI IEC 61850 is not meant for deployment as an Installer/Executable in any system without RT OS.
