Dedicated H-SYNC interfaces provide synchronization between the redundant controllers, while PROFINET interfaces provide communication with distributed I\/O, HMI systems, drives and other industrial equipment.\u003c\/p\u003e\n\u003cp\u003eAs an HF controller family, CPU 1518HF additionally supports fail-safe automation and PROFIsafe communication for safety-related machine and process applications. Standard and safety functionality can therefore be integrated within the high-availability control architecture.\u003c\/p\u003e\n\u003cp\u003eCPU 1518HF controllers are suited to critical production systems, infrastructure, process applications and complex machinery where unplanned controller downtime can have significant operational consequences and functional safety is also required.\u003c\/p\u003e","brand":"SIEMENS","offers":[{"title":"CPU 1518HF-4 PN - High-Availability Fail-Safe - 9MB\/60MB - 3× PROFINET + 2× H-SYNC - 24V DC - 6ES7518-4JP00-0AB0","offer_id":49542107431139,"sku":"ID 01030042","price":35969.99,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0751\/5956\/8611\/files\/Screenshot_2026-08-16_at_2.38.16_PM.png?v=1786848268","url":"https:\/\/www.electrotk.com\/products\/siemens-simatic-s7-1500h-cpu-1518hf-high-availability-fail-safe-plc","provider":"Electrotk","version":"1.0","type":"link"}
