Features:
- Executes S7-400 control logic with equal 1.4 MB code and data areas.
- Provides one MPI/DP connector and one dedicated PROFIBUS DP connector.
- Coordinates a central rack and the configured S7-400 expansion-rack structure.
Siemens 6ES7416-2XK04-0AB0 combines high-capacity program execution with two fieldbus-capable communication channels.
Fast bit, word and integer processing supports the cyclic program, while floating-point instructions use a separate documented execution time.
The CPU diagnostic buffer, clock resources and interrupt handling provide the internal services used to supervise the running S7-400 project.
The Siemens 6ES7416-2XK04-0AB0 SIMATIC S7-400 CPU 416-2 may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Code, Data, and Load Storage
- Work Memory: Work memory is divided into separate 1.4 MB code and 1.4 MB data areas.
- Load Memory: The integrated load memory provides a RAM area for the active configuration.
- Removable Card: A removable RAM or FLASH card extends load memory according to the project requirement.
How the Two Interfaces Differ
- First Interface: The first interface can be assigned to MPI or PROFIBUS DP communication.
- Second Interface: The second interface is reserved for PROFIBUS DP traffic.
- DP Mastering: Both integrated DP interfaces can coordinate distributed stations as masters.
Central and Expansion Layout
- CPU Position: 6ES7416-2XK04-0AB0 occupies the CPU position in the S7-400 central rack.
- Rack Expansion: The configured station can connect the central rack with expansion racks through the S7-400 architecture.
- Configuration Match: Rack addresses and module placement must match the hardware configuration downloaded to the CPU.
Program Execution Resources
- Code/Data Split: Separate code and data areas support deterministic execution of the S7-400 user program.
- CPU Resources: Timers and counters are available as CPU resources for sequence and timing logic.
- Cycle Load: The selected communication load and rack configuration contribute to the overall program cycle.
