More Information

Overview Manuals Memory Structure Dual Bus Roles Rack Operation Cycle Control

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).
Siemens 6ES7416-2XK04-0AB0 SIMATIC S7-400 CPU 416-2 Manuals,Datasheets,Link 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.
Description
At the center of a SIMATIC S7-400 station, Siemens 6ES7416-2XK04-0AB0 serves as a CPU 416-2 with 2.8 MB of work memory. Code and data each receive 1.4 MB, allowing the processor to keep the two memory areas distinct during program execution.

Two communication routes define the network role of 6ES7416-2XK04-0AB0. Its first connector can operate as MPI or PROFIBUS DP, while the second connector is dedicated to PROFIBUS DP; both integrated DP interfaces can act as masters for distributed I/O.

Program retention on 6ES7416-2XK04-0AB0 uses the CPU backup arrangement together with a removable RAM or FLASH memory card. The controller supports a central rack plus expansion racks, so the rack configuration and memory-card type must be set before the user program is loaded.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What memory check should be made when a program will not fit on 6ES7416-2XK04-0AB0?
A transfer failure on 6ES7416-2XK04-0AB0 calls for separate checks of code/data work-memory allocation and configured load memory; unused space in one area does not compensate for a shortage in the other.
How can a technician isolate a bus fault on 6ES7416-2XK04-0AB0?
To isolate a bus fault at 6ES7416-2XK04-0AB0, test MPI and PROFIBUS DP independently, verify both connectors, and compare the configured station address with the wiring.
What should be reviewed after adding an expansion rack to 6ES7416-2XK04-0AB0?
After an expansion-rack change, recheck the rack configuration, interface-module link, address assignment, and diagnostic buffer for 6ES7416-2XK04-0AB0. A structure mismatch can place the CPU in STOP.
Why can 6ES7416-2XK04-0AB0 enter STOP after a hardware change?
If 6ES7416-2XK04-0AB0 enters STOP after hardware work, compare the loaded configuration with installed modules and interface connections before evaluating the user program or cycle performance.
Which resource figures matter when cycle time increases on 6ES7416-2XK04-0AB0?
Cycle-time diagnosis on 6ES7416-2XK04-0AB0 should combine code/data memory use, communication load, and diagnostic events; program size alone cannot explain a symptom caused by bus traffic.
