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.","metaTitle":"Siemens 6ES7514-2DN03-0AB0 CPU 1514-2 PN, PROFINET, No IRT","metaDescription":"Siemens S7-1500 CPU 1514-2 PN, 6ES7514-2DN03-0AB0, with DCP, DNS, MRP, Modbus TCP, PID.
