Siemens 6GK1143-0AB01 is a SINEC H1 CP 143 TF communication processor for connecting SIMATIC S5 controllers to Ethernet. Siemens documentation describes this version as an AP/TF communication processor with a 15 V module design.
The CP 143 TF belongs to the legacy SINEC H1 architecture. When replacing the card, preserve the communication configuration and verify the exact hardware variant. A physical Ethernet connection does not mean automatic compatibility with modern PROFINET or standard TCP/IP communication used in newer systems.
Manufacturer documentation is available from Siemens Industry Online Support. Related SINEC communication processors in the POLRAD catalog include 6GK1147-3MA00 and 6GK1143-0TB01.
If you plan to replace this module with a newer communication platform, first check the protocols used by the PLC project and the devices on the other side of the network.
