It preserves S5 compatibility and supports PG\/OP access and S7-to-PLC communications, making it a versatile link within the SIMATIC NET family. As a PROFIBUS DP master, the CP 443-5 Extended handles standard data exchange and supports DP V1 features, time synchronization, and advanced routing options including data-record routing, enabling deterministic communication across the plant. The module also offers synchronization modes (sync\/freeze) and redundancy capabilities for higher availability in critical automation applications. Typical uses include linking S7-400 CPUs to PROFIBUS DP I\/O blocks, drives, remote I\/O, and other PROFIBUS devices, while maintaining robust S7 communication channels and network management through CiR routing capabilities. Installed in the S7-400 rack, this CP functions as a dedicated DP master within SIMATIC NET, facilitating reliable, scalable fieldbus communications for industrial automation tasks.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268622668010,"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-6gk7-443-5dx03-0xe0-profibus-communication-module","provider":"GTG Hardware","version":"1.0","type":"link"}
