WINCC OA and S7-1500

[funkey]

Hello.
Is it possible to connect a S7-1500 to WINCC OA 3.11.1? And how to do it? I switched the DBs to non optimized DBs but I even cannot connect to the CPU. Is there any way to do this?

Thanks.

You need to enable "Allow PUT/GET Communication" (under the CPU Protection properties in V12/V13) and the driver connects faster when you use the s7 config entry 'UseConnections = 1'.

Thanks for your answer. I found out how it works already yesterday. I cannot swith to 'UseConnections = 1' because of 22 other PLCs and huge amounts of data that I could not receive with one connection every two seconds. I don't think this setting can be set for every PLC!?

The 'useConnections = 1' cannot be set for a single PLC. What you can do is to add a s7 driver with this setting for the S7-1500.
