Configurations with the ST7 protocol
Below, you will find configuration examples for stations with a CP 1243-8 IRC.
Telecontrol communication - MSC
In telecontrol communication the station communicates via the CP with a master station.
Communication can take place via various interfaces of the CP and via various network
types.
In the sample configuration shown, stations communicate with a master station TIM that in
turn is connected to a master station of the type SINAUT ST7sc:
● An S7-300 that only communicates via the Internet.
● An S7-300 that communicates via the mobile wireless network and the Internet.
● An S7-1200 with CP 1243-8 IRC that communicates via the mobile wireless network and
the Internet.
All three stations use the transport protocol MSC (or MSCsec).
