The CP 1242-7 communications processor is used to connect a SIMATIC S7-1200 to the globally widespread 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)
• On-demand connection buildup via voice call or text message
• Sending and receiving of text messages
• Clearly laid out LED signaling for fast and easy diagnostics
• Compact industrial enclosure in S7-1200 design for mounting on a standard mounting rail
• Fast commissioning thanks to easy configuration using STEP 7

In conjunction with the TeleControl Server Basic software, the CP 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 STEP 7 to the substations via the Internet
