Siemens 6GK7242-5DX30-0XE0 CM 1242-5 PROFIBUS DP Slave Module
A compact S7-1200 communications module that connects the station to PROFIBUS as a DP slave through a 9-pin RS-485 interface.
Technical Summary
PRODUCT CONTEXT6GK7242-5DX30-0XE0 is the SIMATIC CM 1242-5 communications module for integrating an S7-1200 station as a PROFIBUS DP slave. A 9-pin D-sub female connector provides the RS-485 network interface, while module power is supplied through the S7-1200 backplane.
The device belongs to the slave side of the PROFIBUS architecture. It should not be substituted for a CM 1243-5 master merely because the enclosure and connector format are similar.

Compatibility
SELECTION BOUNDARIESController station
Confirm the S7-1200 CPU, expansion arrangement and engineering software release support the installed communications module.
Master configuration
Match the station address, module configuration and process-data length to the PROFIBUS master project.
Network hardware
Use approved PROFIBUS cable, connector, shielding and end-of-segment termination; do not treat ordinary serial cabling as equivalent.
Replacement
SERVICE WORKFLOWArchive
Save both the S7-1200 project and the master-side hardware configuration, including node address and data map.
Install
Remove network power under the site procedure, transfer the bus connector and fit the exact slave module.
Prove
Confirm the slave reaches data exchange and verify every mapped input and output against the master diagnostics.
FAQ
CUSTOMER DECISION SUPPORTIs 6GK7242-5DX30-0XE0 a PROFIBUS master?
No. Siemens defines this catalog number as a CM 1242-5 PROFIBUS DP slave module.
What connector is used by 6GK7242-5DX30-0XE0?
The network interface is a 9-pin D-sub female RS-485 connector intended for approved PROFIBUS hardware.
What evidence should accompany a 6GK7242-5DX30-0XE0 enquiry?
Provide the CPU MLFB, node address, network drawing, master configuration record and a clear photograph of the complete label.
Can 6GK7242-5DX30-0XE0 be exchanged without the master project?
The hardware can be physically replaced, but the station cannot be accepted until its address and process-data map match the master configuration.
How is 6GK7242-5DX30-0XE0 accepted after service?
Verify module diagnostics, PROFIBUS data exchange and the correct direction and value of every mapped process signal.
