The Siemens 6GK1143-0TB01 CP 1430 TF Extended communications processor provides a PROFINET IO interface for SIMATIC S7-300 controllers, enabling them to connect to Industrial Ethernet networks. The Extended variant adds enhanced functionality over the Basic model and delivers 1 ms timing accuracy for real-time PROFINET IO data exchange. Designed to retrofit or upgrade legacy S7-300 systems, it serves as a bridge between the PLC and PN IO devices on Ethernet networks and is part of the SIMATIC NET family.
