Order No.: 6GK7242-7KX31-0XE0 6GK72427KX310XE0 Communications processor CP 1242-7 V2 for connection of SIMATIC S7-1200 to GSM/GPRS network; Web server access to CPU, data point configuration, Observe national approvals6GK72427KX310XE0_datasheet_en
Overview
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 kbps in the downlink and 43 kbps in the uplink
GPRS mode with fixed IP addresses and dynamic IP addresses with standard mobile phone contract
Time synchronization based on 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 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
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.
Application
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
