It provides the SINEC H1 network interface and handles the physical, data link, and network layers of the ISO\/OSI stack, while the CPU runs the user program; it exchanges data with the S5 CPU via a dual-port RAM link over the S5 backplane bus. The -0AB01 suffix denotes a +15 V DC power-supply variant. This CP143 module is designed for use in S5-135U and S5-155U configurations and can be used with the S5-115U\/H family with a mechanical adapter due to footprint differences. In practice, it enables Siemens S5 PLCs to communicate over the SINEC H1 network with remote devices and other S5 controllers, acting as the network interface between the S5 CPU and the SINEC H1 communications fabric. Common deployment involves integration into legacy automation cells where reliable H1 connectivity between S5 racks is required, with the CP143 handling low-level networking tasks so the CPU can focus on control logic. This module is part of Siemens' SIMATIC S5 ecosystem and is referenced by multiple suppliers under the CP143\/6GK1-143-0AB01 family, including alternate designations such as 6GK1-143-0AB01 and 6GK1143-0AB01. \u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268610380010,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6gk1-143-0ab01-programmable-logic-controller-cpu-module","provider":"GTG Hardware","version":"1.0","type":"link"}
