The equipment used in the stations or the control center depends on the particular
application.
● For communication with or via a central control room, the control center requires a PC
with Internet access.
● Apart from the station equipment, a remote S7-1200 station with a CP 1242-7 must meet
the following requirements to be able to communicate via the GSM network:
– A contract with a suitable GSM network provider
If GPRS is used, the contract must allow the use of the GPRS service.
If there is to be direct communication between stations only via the GSM network, the
GSM network provider must assign a fixed IP address to the CPs. In this case,
communication between stations is not via the control center.
– The SIM card belonging to the contract
The SIM card is inserted in the CP 1242-7.
– Local availability of a GSM network in the range of the station
