Siemens 6GK1543-0AA02 is a SIMATIC NET SINEC L2 CP 5430 TF communication processor designed for legacy SIMATIC S5 PLCs (115U/135U/155U) and provides a PROFIBUS DP interface to connect S5 controllers to DP networks. The module includes a PG interface for programming/maintenance, a SINEC L2 interface for network connectivity, and an FO interface for fiber-optic communication, all in a compact CP 5430 TF form factor. This interface enables data exchange between the S5 PLC and PROFIBUS DP devices, making it suitable for retrofits, diagnostics, and integration of older S5 systems with modern industrial networks.
