The CP 1242-7 GPRS V2 communications processor is used to connect a SIMATIC S7-1200 to the globally available GSM/GPRS mobile radio network and has the following characteristics:

• Worldwide wireless exchange of data between S7-1200 controllers and/or between S7-1200 controllers and control centers with an Internet connection
• Communication based on the GPRS (General Packet Radio Service) mobile wireless service with data transmission speeds of up to 86 Kbit/s in the downlink and 43 Kbit/s in the uplink
• GPRS mode with fixed IP addresses and dynamic IP addresses with standard mobile phone contract
• Time synchronization on the basis of NTP (Network Time Protocol)
• Sending and receiving of text messages
• LED signaling for fast diagnostics
• Compact industrial enclosure in S7-1200 design for mounting on a standard mounting rail
• Fast commissioning thanks to easy configuration using STEPВ 7

In conjunction with the TeleControl Server Basic software, the CPВ 1242-7 forms a telecontrol system with additional properties:

• Connection of up to 5000 telecontrol stations to the control center via an OPC interface
• Data buffering in the substations in the event of connection failures
• Central status monitoring of the substations
• No special provider services required for fixed IP addresses
• Teleservice access with STEPВ 7 to the substations via the Internet

The CP 1242-7 V2 is a new product version of the CP 1242-7. The concept for process data transmission has been expanded with a simple data point configuration, which enables substantially easier commissioning without high programming overhead and minimizes susceptibility to errors during the projects implementation phase. CP 1242-7 has also been equipped with new functions, such as access to the internal Web server of the S7-1200. This opens up numerous new application areas.
