Now, we’re going to see how SCADA (OPC Server) communicates with an OPC Client PC.
UltimateAccess (CIMON-SCADA) OPC Server Communication with an OPC Client PC
1. Execute CimonD and open a new project.
2. Register a group tag named “A.” This group tag name will be identical with OPC tag.
3. Go to UltimateAccess installation folder and open “OpcTag.ini” file.
4. When you first open it, the “OpcTag.ini” file will be displayed as below.
5. Edit the name of the OPC group tag to “A” as previously configured in CimonD
6. Ensure that the group tag “A” in CimonD is identical with that of OpcTag.ini file
7. Save the OpcTag.ini file and run CimonX. CimonX must be running at all times in order to communicate between OPC Server and OPC Client.
8. Run “OPC Client1.exe” file from the [OPC Server Components] folder downloaded from CIMON website.
9. Go to [OPC] → [Connect] and select “KDT systems.CmHOPCSvr” for OPC Serve
