Siemens 6ES7513-1AM03-0AB0 SIMATIC S7-1500 CPU 1513-1 PN 600KB PROFINET IRT Programmable Logic Controller

The Siemens 6ES7513-1AM03-0AB0 is a SIMATIC S7-1500 CPU 1513-1 PN with 600 KB of work memory for program and 2.5 MB for data, a 6 ns typical bit-instruction time, and an integrated 2-port PROFINET IRT interface. It requires a SIMATIC Memory Card, supports up to 32 GB load memory, and controls up to 128 connected PROFINET IO devices.

Technical Specifications

Selection Notes

The 600 KB program and 2.5 MB data memory with a 6 ns bit time put the 1513-1 PN in the mid-range of the S7-1500 CPU line - enough headroom for a machine or small process cell with distributed I/O, but a CPU with larger memory is the right choice if the program approaches the 4,000-block limit or the 216 KB retentive data ceiling. The integrated 2-port PROFINET IRT switch supports isochronous mode down to a 500 microsecond cycle, relevant for motion-control axes needing tight synchronization; for standard I/O without isochronous timing, IRT capability is not a deciding factor. A SIMATIC Memory Card is mandatory - the CPU will not boot without one.

Applications

Machine and process control with PROFINET-distributed I/O, including applications needing isochronous real-time communication for coordinated motion axes, open Ethernet communication, and web-server diagnostics via TIA Portal.
