More Information

Overview Manuals Memory Backup Two DP Paths Multicomputing CiR Changes

Features:

  • Siemens 6ES7416-2XN05-0AB0 provides 5.6 MB of work memory split between code and data.
  • Two integrated PROFIBUS-capable interfaces support separate station and field-device paths.
  • The S7-400 backplane supplies the processor and connects it to central-rack resources.
The CPU memory arrangement distinguishes the active work areas from load memory on a Flash or RAM card and battery-backed content.

One interface can retain MPI access while the second handles a larger DP master segment, or both can be assigned according to the station project.

Expansion-rack and multicomputing options make central-rack slot selection, backplane capacity and cross-CPU communication part of the system design.

The Siemens 6ES7416-2XN05-0AB0 SIMATIC S7-400 CPU 416-2 Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

Separating active and stored content

  • Code area: One half of the work memory is reserved for executable program content.
  • Data area: The other half holds process and program data used during execution.
  • Load extension: A compatible Flash or RAM card expands the storage available for the project.
  • Battery role: The backup battery preserves the documented RAM contents when backplane power is removed.

Assigning the serial interfaces

  • First path: The MPI/DP interface can combine engineering access with a configured station network.
  • Second path: The additional DP interface supports a separate master segment with its own node group.
  • Rate agreement: All nodes on each segment must share a supported PROFIBUS transmission rate.
  • Address separation: Station addresses are planned independently for the two configured networks.

Sharing an S7-400 central rack

  • CPU grouping: Supported UR1 or UR2 arrangements can house multiple processors in one central rack.
  • Task division: Each CPU executes its own program while the station project defines cross-CPU data exchange.
  • Backplane sharing: The processors use common central-rack resources without merging their program memories.
  • Slot planning: CPU positions and assigned modules must match the configured multicomputing layout.

Controlled configuration updates

  • Running station: Supported configuration-in-run changes are applied within the documented S7-400 CiR limits.
  • Change scope: Only permitted hardware and parameter modifications qualify for an online update.
  • Project match: The engineering station and CPU configuration must remain synchronized after the change.
  • Restart boundary: Modifications outside the CiR scope require the normal stop or restart procedure.
Description
Siemens 6ES7416-2XN05-0AB0 is a SIMATIC S7-400 CPU 416-2 central processing unit. It executes the automation program with work memory divided equally between code and data while drawing operating power from the S7-400 backplane.

Load memory for 6ES7416-2XN05-0AB0 can be extended with a supported Flash or RAM memory card. A backup battery preserves the specified RAM contents, making card type and backup condition part of the controller memory plan.

Two integrated serial interfaces organize communication on 6ES7416-2XN05-0AB0. The first can operate as MPI or PROFIBUS DP, while the second supplies a separate DP master path for a larger group of field devices.

An S7-400 station can combine 6ES7416-2XN05-0AB0 with expansion racks and, in supported central-rack arrangements, multiple CPUs. Backplane resources and communication assignments therefore must be planned at station level rather than only at the individual processor.

Engineering access to 6ES7416-2XN05-0AB0 uses the documented STEP 7 release for its hardware and firmware level. Diagnostic-buffer entries, status/control functions and configuration-in-run features separate commissioning changes from normal cyclic program execution.
