I want to check what the necessary steps are, for configure a S7 program to be accesses through OPC in a user application.
I read and downloaded the entry
“Individual Visualization with OPC based on Microsoft® .NET and the Programming Language C#” entry ID: 21043779
But I had CPU 318-2, so I changed the CPU in hardware configuration and downloaded the program to the PLC. I did all steps mentioned in the manual and every thing seems to work properly ( I mean the C# program can simulate every thing). The problem is when I try to browse the OPC server via another OPC client (for example OPC scout), it doesn’t browse the symbols which has bin defined in “sti” file and in the property of OPC S7 tab.
If I add a new Item in OPC scout I can see it in another OPC client!!! Even if I don’t save the project in OPC scout.
Please help me to figure out the problem.
I have attached a snapshot of OPC scout and property of OPC S7 tab.
