Hello, 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.  In VTScada I tried to set up an OPC Client as shown below.  As you can see, VTScada has no problem finding the server. However, when I try to add a child analog input to the OPC Client I don't see the tags button next to the address box.  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.

I solved this issue by simply creating a new VTScada application. For some reason the application I was previously using would not allow me to connect
