Darius Tudor Podina Posts: 15 Rating: (0)	Hello. I have a CPU 1512SP-1 (6ES7 512-1DK01-0AB0) and I would like to communicate with an OPC DA server, is this possible? or only with OPC UA?

So you would need an OPC DA Server that is able to do a S7 communication to the PLC. for example the SIMATIC Net OPC Server could do this. If you use a third party Server (there are plenty on the market) then you should activate the Put/get communication in Security Settings and use non optimized DBs. Bye Murof
