Siemens 6ES7517-3AP00-0AB0 S7-1500 CPU 1517-3 PN/DP 2MB/8MB Programmable Logic Controller

The Siemens 6ES7517-3AP00-0AB0 is a SIMATIC S7-1500 CPU 1517-3 PN/DP with 2 MB program memory and 8 MB data memory, running bit operations at 2 ns. It provides three interfaces: PROFINET IRT with an integrated 2-port switch, a second PROFINET RT port, and a third PROFIBUS port, and requires a SIMATIC Memory Card to operate.

Technical Specifications

Selection Notes

The three interfaces split network duties: the first PROFINET port runs IRT through an integrated 2-port switch for isochronous motion I/O, the second PROFINET port carries standard RT traffic, and the third, PROFIBUS, connects legacy fieldbus devices on the same CPU without an external gateway. At 2 ns per bit operation and 8 MB of data memory, it has headroom for recipe or data-logging-heavy programs beyond what a smaller-memory CPU in the same PN/DP line offers. A SIMATIC Memory Card is mandatory - the CPU will not run without one plugged into its single card slot.

Applications

Machine or line control that mixes isochronous PROFINET IRT motion I/O with standard PROFINET RT devices and legacy PROFIBUS field equipment on one CPU, particularly where program or data memory beyond a base S7-1500 CPU is needed.
