Pretty much as the thread title says.

I understand it currently connects to S7-300, S7-400, S7-1200.

But will the current Siemens driver talk to an S7-1500 PLC?

I’ve been asked by someone who (I guess) is considering buying one (the PLC that is).

I haven’t got one myself so obviously cannot just go ahead and try it.

Thanks.

It does, with a few caveats:

1. Only global DBs can be accessed.
2. The optimized block access must be turned off.
3. The access level must be “full” and the “connection mechanism” must allow GET/PUT.
4. No read/write to TM/CT areas (applies to S7-1200 as well).

This stuff should go in the user manual soon.

Kevin,

Thanks for the prompt reply.  
Your information has gone over my head as I don’t know anything about Siemens PLCs myself but I will pass it on.
