Hi, we are a group of students in Norway and we are trying to make an OPC-client that works over ethernet. We downloaded VB example from Steeplechase and it works fine when the OPC-server is on the same PC as the client. We can´t get it to connect to a server which is on the same network. That´s why we opened a new VB project using the opcdaauto.dll and its methods but it still can´t find nor connect to another OPC-server. Are there any restrictions on the dll?
We have done dcomcnf.exe but it still doesn't work over network.We have tried also "DrDCOM" from intellution, but it can't get access to registry. What else have we got to do to get any client-server communication over network?
We use NT4-server and NT4Workstation on pentium PC. Don't have any PLC , but think to use Iconics simulation-server in the beginning.
Grateful in advance
