Siemens 6ES7517-3AP00-0AB0 SIMATIC S7-1500 CPU 1517-3 PN/DP
01Technical Summary
Siemens 6ES7517-3AP00-0AB0 is the SIMATIC S7-1500 CPU 1517-3 PN/DP with 2 MB program work memory and 8 MB data work memory. It combines a PROFINET IRT two-port interface, a second PROFINET RT interface and PROFIBUS, while a typical 2 ns bit-operation time supports high-performance machine and plant control. The CPU requires a SIMATIC Memory Card and must be selected with its exact firmware, engineering version and installed network architecture.
