Features:
- PROFIBUS DP master operation
- Up to 32 DP devices
- PG/OP and S7 communication support
The Siemens 6GK7243-5DX30-0XE0 is a SIMATIC NET CM 1243-5 communication module for operating a SIMATIC S7-1200 station as a PROFIBUS DP master. It communicates through a 9-pin Sub-D RS485 socket. Supported PROFIBUS transfer rates extend from 9.6 kbit/s to 12 Mbit/s. The module also supports the PG/OP and S7 communication functions identified in the Siemens documentation.
A maximum of 32 DP devices can be operated within the stated system limits. The total DP master input address range is 512 bytes, and the total output address range is also 512 bytes. The module uses an external 24 V DC supply with a tolerance of ±20 percent and supports up to eight S7 connections. Its enclosure is rated IP20 for installation in the specified industrial environment.
Select this order number when the S7-1200 station must coordinate PROFIBUS DP devices as the master. The engineering project should verify the number of slaves, the configured addresses, the data areas and the required communication connections. Bus termination, cable routing and shielding must follow the PROFIBUS network design. Supply wiring and STEP 7 configuration should be confirmed before the system is placed into service.
DP-master expansion with the 6GK7243-5DX30-0XE0 can be supported through device-count, configuration and sourcing checks. Siemens lists product phase-out from 1 October 2026; current availability is confirmed before quotation.
