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
