It supports DCP, DNS, DHCP, HTTP, HTTPS, and TCP/IP out of the box — so device discovery, web-based diagnostics, and standard TCP socket communication are all available from the first download, no extra configuration overhead. The process image handles 32 kbyte inputs and 32 kbyte outputs — enough for a couple of hundred digital points plus analog channels typical of a packaging line, a conveyor section, or a small process skid. Ambient temperature range spans -40 °C to 70 °C, which means this CPU can sit in an unheated mill mezzanine or a refrigerated warehouse without a cabinet heater or air conditioner. ## Network redundancy and fieldbus profile MRP (Media Redundancy Protocol) is supported with Automanager and Client roles per IEC 62439-2 Edition 2.0 — a ring topology recovers in under 200 ms on a typical PROFINET ring, which keeps the line running through a cable break or switch failure. IRT is not supported on this CPU, and MRPD (which requires IRT) is therefore unavailable. If your application needs isochronous motion control with synchronized axes over PROFINET, step up to a CPU that carries IRT hardware. MODBUS TCP is supported natively, so integrating with third-party drives, remote I/O, or legacy SCADA systems that speak MODBUS does not require a separate gateway module. ## Built-in control and programming languages The CPU has integrated PID controllers for temperature and for valve positioning — both with automatic tuning — which saves a separate loop controller on simple process loops like a dryer section or a valve actuator. Programming languages include LAD, FBD, SCL, STL, and GRAPH — the full TIA Portal palette — so the team can write in whatever dialect suits the application. PROFIsafe is not supported — this CPU is not intended for fail-safe control loops that need safety-related communication over PROFINET.","metaTitle":"Siemens 6ES7515-2TN03-0AB0 CPU 1515-2 PN, -40 to 70°C","metaDescription":"Siemens S7-1500 CPU 1515-2 PN, 32 kB I/O process image, MRP, MODBUS TCP, -40 to 70 °C.
