I'm using ModBus IO Server in LabVIEW DSC module to communicate with a device using a RS-485 to USB converter. I was able to install the converter driver and communicate using the converter vendor's application, but when I go to LabVIEW, the bound variable in my VI returns the following error:Error -1967353900 ocurred at Shared Variable in Untitled1.vi
LabVIEW DSC: (Hex 0x8ABC8FD4) The Modbus I/O server failed to allocate a serial port. Ensure that the specified serial port is available.
This error or warning occurs while writing the following Shared Variable
How can I troubleshoot this error?
