Good morning all.

please i would like to know if it is possible to exchange values via gms (gprs) beetween  a logo and a s7-1200. and were can i find documentation about it

Hello,

one idea is:

Use OpenVPN.

==>Logo CMR 2020 supports Remote Access via OpenVPN as Server and PSK

==> S7-1200 needs a module e.g. SCALANCE M876 (mobile) or S615 (internet) (both supports OpenVPN as Client)

Then you can build up a secure connection between both.
