Siemens 6ES7512-1DM03-0AB0 SIMATIC S7-1500 CPU 1512SP-1 PN 400KB/2MB PROFINET IRT PLC

The Siemens 6ES7512-1DM03-0AB0 is a SIMATIC S7-1500 CPU 1512SP-1 PN for the ET 200SP distributed I/O system, with 400 KB of integrated work memory for program and 2 MB for data. Its PROFINET interface has an integrated 3-port switch with IRT support and 6 ns bit-instruction processing. The CPU requires a SIMATIC Memory Card and a BusAdapter for ports 1 and 2, both ordered separately.

Selection Notes

400 KB of program memory and 2 MB of data memory position this CPU above the base S7-1500 entry points for machine control programs with multiple technology objects or larger recipe/data-logging structures. The integrated 3-port PROFINET switch with IRT support removes the need for an external switch when daisy-chaining ET 200SP stations that require isochronous drive synchronization; projects without IRT requirements can use a lower-cost CPU in the same rack format. Because the SIMATIC Memory Card and BusAdapter are ordered separately, confirm both are in the same cart before commissioning.

Applications

Machine and process controllers built on the ET 200SP distributed I/O platform, including applications needing PROFINET IRT for coordinated axis motion or tight cycle-time synchronization across multiple stations.
