Applications

The CPU 1517H-3 PN is designed for high-availability automation systems where downtime carries significant cost or risk:

• Process Industries: Chemical, pharmaceutical, and petrochemical plants requiring continuous operation

• Energy & Utilities: Power generation and distribution control systems with redundancy requirements

• Water & Wastewater: Treatment facility automation where process continuity is critical

• Infrastructure: Transportation and traffic management systems demanding high availability

• Manufacturing: Production lines where unplanned downtime is unacceptable

Key Benefits

Important Notes

• Memory Card Required: A SIMATIC Memory Card is mandatory for operation; it is not included with the CPU.

• Redundancy Pair: For S7-1500H operation, two identical CPUs are required along with appropriate synchronization cabling and configuration. Both CPUs must have the same article number and firmware version.

• No IRT Support: PROFINET IRT and isochronous mode are not supported on this CPU.

• Firmware Update: Firmware updates can be performed via TIA Portal, SIMATIC Memory Card, or the integrated web server. A downgrade is possible for firmware version alignment.

• Not a Safety CPU: Available data indicates this CPU is not suitable for safety functions. For fail-safe applications, consider the CPU 1518HF-4 PN or other F-CPUs.

• Product Lifecycle: Verify current availability and lifecycle status with Siemens or authorized distributors before ordering.

FAQ

Q1: What is the primary function of the 6ES7517-3HP00-0AB0?

A: It is a high-availability CPU for the SIMATIC S7-1500H redundant automation platform. It operates in pairs with dedicated H-SYNC interfaces to provide maximum system uptime for critical processes.

Q2: What are the memory specifications?

A: The CPU provides 2 MB work memory for program and 8 MB work memory for data. A SIMATIC Memory Card (max. 32 GB) is required for load memory and is not included.

Q3: What communication interfaces does this CPU have?

A: It features two PROFINET interfaces (one with a 2-port switch) and two H-SYNC interfaces for redundant synchronization.

Q4: Does this CPU support PROFINET IRT?

A: No. Available documentation indicates that IRT and isochronous mode are not supported on this CPU model.

Q5: Can I use a single CPU 1517H-3 PN without redundancy?

A: The CPU is designed for S7-1500H redundant configurations. For non-redundant applications, standard S7-1500 CPUs are the appropriate choice.

Q6: What software is required for programming?

A: Configuration and programming require TIA Portal V19 (for firmware V3.1) or V15.1 and higher for earlier firmware versions.

Q7: Is this CPU suitable for safety applications?

A: Based on available data, this CPU is not suitable for safety functions. For fail-safe applications, consider the CPU 1518HF-4 PN or other F-CPUs from the S7-1500 series.

Q8: What happens during a firmware update?

A: The CPU goes to STOP during the update process, which typically takes less than 3 minutes. Retentive data is preserved after the update.
