Application Scenarios of SIEMENS 6ES7414-5HM06-0AB0 (CPU414-5H PN/DP)

This CPU is a medium-sized redundant PLC of the S7-400H series, equipped with MPI/DP, independent DP and PROFINET interfaces and a total work memory of 4 MB. It supports millisecond-level bumpless redundancy switchover and targets medium-to-large industrial processes requiring zero downtime, 높은 신뢰성, hybrid multi-bus communication and process safety. Classified scenarios by industry are listed below:

1. 석유화학 & Coal Chemical Industry (Most Mainstream Application)
2. Refining Units: Main process control for atmospheric-vacuum distillation, catalytic cracking, hydrogenation and reforming units; redundant interlock control of furnace temperature, pressure and flow to eliminate risks of oil leakage and explosion caused by system shutdown.
