Product details

CPU 414-2 DP for S7-400 Racks

The Siemens 6ES7414-2XJ01-0AB0 is a SIMATIC S7-400 CPU 414-2 DP central processing unit. It carries an integrated multi-point MPI interface and a separate PROFIBUS DP interface, with 384 KB of working memory for program and data. This is the processor that sits in the S7-400 rack, handling logic execution and fieldbus communication for mid-to-large automation systems.

The 384 KB working memory is the key constraint for program size and data blocks. For an existing S7-400 system, this CPU handles a moderate-sized control program — think a few hundred I/O points with standard logic and PID loops. The integrated PROFIBUS DP interface means it connects directly to remote I/O racks or drives on a PROFIBUS network without needing a separate communications processor. The MPI port is used for programming (Step 7) and for HMI connections on the same network segment.

Frequently asked questions

What replaces the 6ES7414-2XJ01-0AB0 for new designs?

There is no official direct successor order code for this CPU. For new installations, Siemens moved to the S7-1500 platform, which uses a different rack and backplane architecture. For an existing S7-400 rack, this CPU remains the correct replacement part.

Will the 6ES7414-2XJ01-0AB0 work in a panel specified for a different S7-400 CPU?

Yes, it fits any standard S7-400 rack (UR1 or UR2) and uses the same backplane bus. The key check is the firmware version and the Step 7 software version needed to program it — older projects may require a firmware update or a different CPU if the program size exceeds 384 KB.
