1. High-Performance Industrial Processing

The CPU 1517-3 PN/DP is designed for automation projects that require substantial processing capability and memory resources. Its 2 MB program work memory and 8 MB data work memory support control programs, process data and application logic suitable for complex industrial installations.

The specified typical bit operation time of 2 ns makes this CPU suitable for applications where rapid execution of control instructions is important. Actual system performance depends on the program, hardware configuration, communication load and application requirements.

2. PROFINET IRT Communication

The first integrated interface supports PROFINET IRT and includes a two-port switch. This helps connect compatible industrial devices in a PROFINET network and can simplify wiring in supported network configurations.

The interface can be used for communication with compatible distributed I/O, operator panels, drives and other automation devices. Network design should follow Siemens' recommendations and the requirements of the connected equipment.

3. Additional PROFINET RT Interface

A second PROFINET RT interface provides additional options for connecting compatible devices and organizing industrial Ethernet communication. Depending on the application design, the separate interfaces can help structure communication between automation components and connected networks.

Confirm the intended network topology, addressing, communication requirements and supported configuration before commissioning.

4. Integrated PROFIBUS Interface

The third interface supports PROFIBUS communication, helping integrate compatible PROFIBUS devices into an automation system. This can be particularly useful when maintaining or upgrading installations that contain existing PROFIBUS-based equipment.

Compatibility depends on the connected device, bus configuration, required communication functions and system engineering.

5. TIA Portal Engineering and Programming

The CPU is configured and programmed using Siemens STEP 7 engineering software in TIA Portal. The correct software version depends on the CPU firmware and the project requirements. Siemens documentation lists support from specific TIA Portal versions, with newer firmware requiring newer engineering software.

Before programming or replacing a CPU, verify the hardware version, firmware, project compatibility and engineering software requirements.

6. SIMATIC Memory Card Requirement

A compatible SIMATIC Memory Card is required for this CPU. The memory card is used for load memory and related operating requirements. Confirm whether a memory card is included in the product offer before purchasing, as included accessories may vary.

Industrial Applications

The Siemens CPU 1517-3 PN/DP may be used in suitable applications such as:

• Factory and manufacturing automation

• Automated production lines

• Packaging and filling machinery
