I am having a problem reading tags from my OPC Server using VTScada Light. The server is located on an external PC and the connection to the client PC is made through DCOM. I know the DCOM configuration is correct because I can use Matrikon OPC Explorer on the client PC to read all the servers and tags on the external PC. I just can't replicate this within VTScada. This first screenshot shows Matrikon OPC Explorer can successfully read the PLC tags from the external server over DCOM.
I suspect I am simply setting this up incorrectly as the DCOM has been proven to work with Matrikon. Is there anything else I need to do before setting up the OPC Client in VTScada?
I am very new with this program as well as OPC and PLCs so any instructions on how to successfully set this up would be very appreciated.
the PLC I am using is a Beckhoff CX5020.
