Siemens 6ES7416-3FS07-0AB0 SIMATIC S7-400 CPU 416F-3 PN/DP Fail-Safe 16MB Programmable Logic Controller

The Siemens 6ES7416-3FS07-0AB0 is a SIMATIC S7-400 CPU 416F-3 PN/DP fail-safe central processing unit with 16 MB of work memory (8 MB code, 8 MB data) and three interfaces: MPI/DP at 12 Mbit/s, an Ethernet/PROFINET port, and a slot for a plug-in IF 964-DP module. It integrates 1 PROFINET IO controller and 1 DP master.

Selection Notes

The F in CPU 416F-3 PN/DP marks the fail-safe program processing built into this CPU, running standard and safety-related logic on the same module instead of a separate safety CPU. It carries the same 16 MB work memory and PROFINET-plus-PROFIBUS DP interface pairing as the non-fail-safe 416-3 PN/DP, so where a machine has no safety-related I/O to process, the standard CPU 416-3 PN/DP is the lighter choice; where SIL- or PL-rated safety functions run alongside standard control, this F-CPU covers both on one module.

Applications

S7-400 control tasks that mix standard automation logic with fail-safe functions (E-stops, safety interlocks, guard monitoring) on a single CPU, over a combined PROFINET and PROFIBUS DP network.
