CPU 1514-2 PN — PROFINET Controller Without IRT
The 6ES7514-2DN03-0AB0: The CPU supports MRP (Media Redundancy Protocol) as manager and client, along with MRPD (Media Redundancy for Planned Duplication) — but MRPD requires IRT, which this CPU lacks. For applications needing deterministic motion over PROFINET, consider the 6ES7514-2SN03-0AB0.
Firmware-Native Capabilities
Integrated PID controller for temperature with optimization is onboard — no extra library license. Modbus TCP is also native, no additional hardware. The web server supports HTTP and HTTPS for standard and custom user pages, useful for remote diagnostics. Check the firmware revision history for any security advisories on the web server before putting it on an OT network. Supports LAD, FBD, STL, SCL, and GRAPH programming languages. I&M data (I&M0–I&M3) is present for asset management. Forcing is available for inputs and outputs in the process image.
