Siemens 6ES7514-2DN03-0AB0 SIMATIC ET 200SP CPU 1514SP-2 PN 600KB/3.5MB Programmable Logic Controller

The Siemens 6ES7514-2DN03-0AB0 is a SIMATIC CPU 1514SP-2 PN for the ET 200SP station, offering 600 KB of program memory and 3.5 MB of data memory. It has two PROFINET interfaces - a PROFINET IRT port with an integrated 2-port switch via BusAdapter and a second PROFINET RT port - and processes bit operations in 6 ns. A SIMATIC Memory Card and a BusAdapter are required for the first interface.

Technical Specifications

Selection Notes

Because the CPU is built directly into the ET 200SP station rather than a separate S7-1500 rack, it drives up to 64 ET 200SP modules plus 16 ET 200AL modules locally without a head module in between; its second, independent PROFINET port lets it act as IO controller on one interface while staying reachable for engineering or HMI traffic on the other. Pick a rack-based 1513/1511 CPU instead when the application calls for a traditional S7-1500 rack rather than a station-integrated CPU.

Applications

Compact distributed-I/O machine or skid control where the CPU sits directly in the ET 200SP station, including isochronous PROFINET IRT applications that need a 375 us OB 6x cycle.
