Q1: What is the primary function of the 6ES7517-3HP00-0AB0?
It is a high-availability central processing unit for the SIMATIC S7-1500H redundant automation system. It enables redundant (2-out-of-2) configurations, ensuring continuous operation in critical process applications such as power generation, oil & gas, and chemical plants. Two identical CPUs work in parallel, with one acting as Primary and the other as Backup, synchronized via fiber-optic H-Sync interfaces .
Q2: Can the CPU 1517H-3 PN be used in a non-redundant (standalone) configuration?
No. The CPU 1517H-3 PN is specifically designed for S7-1500H redundant systems. It must be paired with a second identical CPU and synchronization modules to form a redundant system. For non-redundant applications, the standard S7-1500 CPUs are required .
Q3: What is the difference between CPU 1517H-3 PN and CPU 1517-3 PN?
The CPU 1517H-3 PN (this model) is the redundant version with H-Sync interfaces for CPU synchronization. The CPU 1517-3 PN (standard version) lacks the H-Sync interfaces and redundancy capability. Both share similar processing performance, but the H variant is specifically engineered for high-availability applications .
Q4: What software is required to program this CPU?
The CPU 1517H-3 PN requires STEP 7 TIA Portal V19 (for firmware V3.1) or V15.1 or higher (for firmware V2.6) . It is programmed using the TIA Portal environment with the S7-1500H redundant system configuration tools. The CPU supports SIMATIC communication (server only), Open IE communication (TCP/IP, ISO-on-TCP, UDP), and OPC UA (runtime license required) .
Q5: What are the key communication and redundancy features?
The CPU supports PROFINET IO Controller (up to 256 IO devices), PROFINET system redundancy (S2 and R1), MRP (Media Redundancy Protocol) with 200 ms switchover time, and S7 routing. It also supports PROFIsafe? No – the standard CPU 1517H does not support PROFIsafe safety communication; for integrated safety, the CPU 1518HF-4 PN is required.
