Julian Feinauer commented on PLC4X-134:
---------------------------------------
Hi [~generalkelly], first, thanks for the Ticket!
I guess we have to include a switch or something there.
Did you test what happens with a S7 1500 or something?
Perhaps [~timbo2k] could check it otherwise.
If you want, we would be happy for a PR otherwise, Tim or I can also prepare a
patch for that. Thank you very much for the contribution!
