Product details

CPU 412-1 for S7-400 Racks

The Siemens 6ES7412-1XF04-0AB0 is a CPU 412-1 for the S7-400 platform, a mid-range processor handling up to 244 bytes each of inputs and outputs — enough process image for a substantial machine or process cell without needing an external IM 153 interface module. It communicates natively over RS-485 / PROFIBUS DP, and can act as a DP client (slave) on the network, which matters if you're pulling this CPU into a multi-master line where it needs to respond to a higher-level controller.

Programming and Engineering

Supports LAD, FBD, STL, SCL, GRAPH, and CFC programming languages. Works with STEP 7 engineering software; the onboard MPI interface lets you connect a PG/PC without an additional CP card for commissioning and diagnostics.

Mechanical Fit and Mounting

At 25 mm wide and 290 mm tall, this CPU occupies one slot on the S7-400 rack — the height is the key dimension to check: it's significantly taller than S7-300 modules, so verify your enclosure depth is at least 219 mm plus cabling bend radius.

Frequently asked questions

What is the maximum I/O this CPU can handle?

The process image supports 244 bytes of inputs and 244 bytes of outputs. Actual physical I/O is limited by the number of slots and connections on the backplane.

Does this CPU have a PROFIBUS interface built in?

Yes, it has a native RS-485 / PROFIBUS DP interface and can operate as a DP client (slave) on the network. Additional PROFIBUS connections are possible via a CP 443-5 Extended communications processor.
