Siemens 6ES7416-5HS06-0AB0 SIMATIC S7-400H CPU 416-5H PN/DP 16MB Fault-Tolerant Programmable Logic Controller

The Siemens 6ES7416-5HS06-0AB0 is a SIMATIC S7-400H CPU 416-5H PN/DP central processing unit for S7-400H and S7-400F/FH fault-tolerant systems, with 16 MB of work memory (6 MB program, 10 MB data) and 5 interfaces: MPI/DP, DP, PROFINET, and 2 ports for synchronization modules. It integrates 1 PROFINET IO controller and 2 DP masters.

Technical Specifications

Selection Notes

The 2 ports for synchronization modules are what set this CPU apart from a standard 416-series module: they link a pair of CPUs into a redundant S7-400H pair, or add fail-safe processing in an S7-400F/FH configuration, neither of which a non-H CPU in the same rack family supports. 16 MB of work memory split 10 MB data / 6 MB program favors data-heavy redundant applications over program size. Where redundancy or fail-safe operation is not required, a standard (non-H) CPU in the 416 family covers the same PROFINET-plus-PROFIBUS DP interface set at lower cost.

Applications

Fault-tolerant and safety-related S7-400H/F/FH process control where a CPU pair must stay synchronized over the dedicated sync-module links while running PROFINET IO and PROFIBUS DP I/O.
