More Information

Overview Manuals Memory Cards MPI/DP Roles CiR Changes Execution Model

Features:

  • Executes S7-400 control logic from equal 1.4 MB code and data work-memory areas.
  • Separates MPI/DP communication from a second PROFIBUS DP interface.
  • Supports memory cards up to 64 MB for project storage and transfer.
The CPU 414-3 combines central program execution with multiple fieldbus routes inside one S7-400 rack module.

An IFM position extends the communication layout without replacing either of the two integrated bus interfaces.

CiR timing coordinates supported distributed-I/O configuration changes while the controller remains in RUN.

The Siemens 6ES7414-3XM05-0AB0 CPU 414-3 Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Project storage choices

  • RAM Load Area: The CPU includes 512 KB of internal RAM load memory.
  • Card Capacity: External memory cards can provide up to 64 MB of project storage.
  • Flash Use: Flash cards retain a transportable project without battery-backed RAM.
  • RAM Use: RAM cards provide writable load memory whose retention depends on backup power.

Assigning the two integrated buses

  • First Interface: X1 can serve MPI communication or a PROFIBUS DP role.
  • Second Interface: X2 provides a separate PROFIBUS DP connection.
  • Engineering Access: MPI permits programming-device and operator communication with the CPU.
  • Distributed I/O: The DP paths exchange cyclic data with configured field devices.

Updating supported I/O in RUN

  • Change Scope: CiR applies to supported distributed-I/O configuration changes while the CPU remains in RUN.
  • Base Interval: A 100 ms basic synchronization interval precedes the transferred change.
  • I/O Contribution: The synchronization time increases by 15 µs for each affected I/O byte.
  • Project Control: Only objects and changes permitted by the S7-400 CiR rules can use this process.

How instructions and data are handled

  • Logic Operations: Bit, word, and fixed-point instructions follow the CPU's short execution path.
  • Floating Point: Floating-point instructions use a longer processing interval than the other documented operation types.
  • Code/Data Split: Program blocks and runtime data occupy separate 1.4 MB work areas.
  • Retentive Data: Battery backup preserves the configured memory areas that require retention.
Description
Siemens 6ES7414-3XM05-0AB0 is a CPU 414-3 central processor for a SIMATIC S7-400 station. It executes the controller program and coordinates distributed I/O through multiple communication paths in the rack.

Project storage on 6ES7414-3XM05-0AB0 is divided between the active work areas, internal RAM load memory, and an optional memory card. Code and runtime data occupy separate work-memory sections, while the card provides the project medium used for retention or transfer.

Configuration changes in RUN use the CiR mechanism of 6ES7414-3XM05-0AB0. A fixed base period plus the affected I/O data determines how long process updates are paused while the supported distributed-I/O change is synchronized.

Communication can be assigned without forcing every connection onto one bus because 6ES7414-3XM05-0AB0 provides an MPI/PROFIBUS DP interface, a second PROFIBUS DP interface, and an IFM expansion position. Engineering access, cyclic field data, and an additional interface can therefore retain distinct roles.

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.
How can 6ES7414-3XM05-0AB0 be distinguished from the later 3XM07 CPU variant?
Verify the complete 6ES7414-3XM05-0AB0 order number, hardware version 03, firmware V5.3, and its 2.8 MB split work-memory configuration.
When should a RAM card be chosen instead of a flash card for 6ES7414-3XM05-0AB0?
Use a RAM card with 6ES7414-3XM05-0AB0 when writable load memory is required and backup power is provided; flash supports nonvolatile project transport.
Which port of 6ES7414-3XM05-0AB0 should remain available for MPI engineering access?
X1 on 6ES7414-3XM05-0AB0 can operate as MPI or DP, so preserve its MPI role when programming-device access is required.
What must be evaluated before applying a CiR change through 6ES7414-3XM05-0AB0?
Confirm that the intended I/O object is CiR-capable and account for the 6ES7414-3XM05-0AB0 synchronization interval and affected I/O bytes.
Why are code and data capacity quoted separately for 6ES7414-3XM05-0AB0?
6ES7414-3XM05-0AB0 reserves one 1.4 MB area for executable blocks and another 1.4 MB area for runtime data.
What engineering version should be available before configuring 6ES7414-3XM05-0AB0?
A 6ES7414-3XM05-0AB0 project requires STEP 7 V5.3 SP2 with the applicable hardware update for this CPU version.
