Using CP1242-7 GPRS V2 enables the S7-1200 to be used as a remote terminal unit (substation) in telecontrol applications. Typical application examples are the collection of measured values in outdoor areas over widely distributed geographical areas (level measurement for water tanks in the water/waste water industry) or centralized opening and closing of valves (oil/gas transport in pipelines).

• Data exchange and centralized data monitoring for automation solutions spread over large geographical areas
• Establishment of permanent or temporary communication link for mobile machines/vehicles without permanent location
• Global remote access to the end customer's machinery in compliance with IT security requirements
• Connection of difficult-to-access external stations without a network infrastructure

These applications can be found in the most diverse sectors:

• Water/wastewater treatment plants – pump/valve controllers
• Traffic and transportation – traffic light controls, lighting controls
• Power engineering – monitoring of transformer stations, meter readout
• Mechanical engineering – centralized remote maintenance of machines used around the world
• Wind energy – condition monitoring of wind turbines
• Vending machine manufacturers – monitoring, control of beverage vending machines
