Siemens 6GK1543-0AA02 SINEC L2 Communication Module

Siemens 6GK1543-0AA02 is the CP5430 TF SINEC L2 communications processor for SIMATIC NET, designed to interface SIMATIC S5 controllers (115U, 135U, 155U) with a SINEC L2 network and PROFIBUS DP devices. This CP5430 TF (A2) module uses CP5430 (A1) as its hardware base and is intended for configuration with the SINEC COM5430 TF system software. The unit measures 20 mm in height, 210 mm in length, and 260 mm in width, and weighs about 0.38 kg. It provides a dedicated SINEC L2 interface to connect SIMATIC S5 programmable controllers to other nodes on the SINEC L2 network, enabling integration with PROFIBUS DP devices on the same network. Typical applications include legacy SIMATIC S5 installations that require reliable L2 communication between the PLC and peripheral devices or other SINEC L2 nodes, making CP5430 TF a bridge between older 115U/135U/155U hardware and modern fieldbus or device networks.
