CPU 414-1 for S7-400 racks
The Siemens 6ES7414-1XG02-0AB0 is a SIMATIC S7-400 CPU 414-1 central processing unit with a multi-point MPI interface and 128 KB of working memory. It executes the user program and coordinates the rack's I/O and communications modules. The 128 KB working memory determines the program and data capacity available for your application logic. For a mid-size S7-400 rack handling a few thousand I/O points and moderate data handling, this CPU is a common fit.
If you are refreshing a panel design, verify that the S7-400 platform still meets your long-term support requirements.
Integration into an S7-400 rack
The CPU 414-1 mounts into a standard S7-400 rack (UR1/UR2) and connects to the backplane bus. The MPI interface allows programming and basic networking with other S7-400 CPUs or operator panels without an additional communications processor.
