CPU 416-2 DP — what this S7-400 processor delivers
The Siemens 6ES7416-2XL01-0AB0 is a SIMATIC S7-400 CPU 416-2 DP central processing unit. It carries an integrated multi-point MPI interface and a PROFIBUS DP interface, with 1.6 MB of working memory. The 1.6 MB working memory determines the program and data capacity available for your application logic. For a mid-range S7-400 rack, this CPU handles distributed I/O over PROFIBUS DP without a separate CP card, saving a slot in the rack.
Integration into an S7-400 rack
The CPU 416-2 DP slots into the standard S7-400 rack (UR1/UR2). The integrated PROFIBUS DP interface connects to remote I/O stations, drives, or other DP slaves without an external communications processor. The MPI port handles programming and HMI connections.
