Siemens 6ES7517-3FP00-0AB0 SIMATIC S7-1500F CPU 1517F-3 PN/DP
01Technical Summary
Siemens 6ES7517-3FP00-0AB0 is the fail-safe SIMATIC S7-1500F CPU 1517F-3 PN/DP. It provides 3 MB program work memory, 8 MB data work memory and a typical 2 ns bit-operation time, together with PROFINET IRT, a second PROFINET RT interface and PROFIBUS. The CPU supports both standard and fail-safe automation tasks, so replacement requires preservation of the safety project, signatures, firmware, device configuration and validation records in addition to normal PLC commissioning.
