OPC redundant configuration with Digivis
i made my redundant configuration through the document which i attached
below.please give me the solution that how i can i make redundant plcs communication with DIGIVIS through Codesys OPC
for DigiVis the PLC redundancy is totally handled by the Codesys OPC server. There is no changve in DigiVis, whether the PLCs are redundant or not, as long as the OPC Server node name and Parameters in the Graphics Builder stay the same.So in my opinion the problem lies in the Codesys OPC server handling.
Here is a tutorial for first steps with DigiVis 500 and Codesys OPC server. It is for a single PLC only, but maybe you see something that helps you.
I have no experience with Codesys OPC server configuration but I'm wondering why the Master Variable is the same for both PLC's. Is that how it has to be?
