Siemens 6GK7242-7KX30-0XE0 CP 1242-7 GPRS Communication Processor
An S7-1200 communication processor for GPRS telecontrol using quad-band GSM service, a SIM card and a 50-ohm SMA antenna connection.
Product Identification
6GK7242-7KX30-0XE0 is the SIMATIC CP 1242-7 processor for connecting an S7-1200 station over GPRS. It supports the four principal GSM frequency bands, contains a SIM-card slot behind the front cover and uses a 50-ohm SMA connector for the cellular antenna.
The module is a packet-radio communication device, not an Ethernet, PROFIBUS or plain serial expansion. Network availability, SIM provisioning, antenna placement and the telecontrol project all determine whether the station can communicate.
Preserve the complete MLFB, module firmware, SIM subscription details, antenna record and remote-station configuration. Radio service cannot be inferred from hardware identity alone.

Applications
Remote utility assets
Unattended pumping, water, energy or infrastructure stations where wired communication is unavailable.
Wide-area telemetry
Distributed S7-1200 sites sending selected process data through a provisioned cellular service.
Legacy GPRS maintenance
Existing installations retaining the approved SIM, antenna, carrier and central telecontrol configuration.
Lifecycle
Capture
Save the project, firmware, station identity, APN and remote-end settings without publishing credentials in the spare record.
Inspect
Record SIM ownership, cellular-service status, antenna type, cable condition, signal evidence and surge protection.
Install
Transfer the SIM only under the authorized process, reconnect the 50-ohm antenna path and restore the approved 24 V DC supply.
Confirm
Verify network registration, central-system connection, expected data transfer, diagnostics and any configured SMS path.
FAQ
Which cellular bands are supported by 6GK7242-7KX30-0XE0?
Siemens lists GSM 850, 900, 1800 and 1900 MHz for the CP 1242-7.
Does 6GK7242-7KX30-0XE0 operate without a SIM subscription?
The processor requires a suitable SIM and provisioned mobile service for the intended GPRS communication.
What should be included with a 6GK7242-7KX30-0XE0 enquiry?
Provide the complete MLFB, CPU and firmware, country and carrier context, antenna identity and requested quantity; do not send live credentials.
Can an ordinary antenna be connected to 6GK7242-7KX30-0XE0?
Use an antenna and cable system compatible with the supported bands and the published 50-ohm SMA interface.
What proves 6GK7242-7KX30-0XE0 has been commissioned correctly?
Document network registration, central-system communication, expected data exchange, signal quality and diagnostics under the approved project.
