More Information

Overview Manuals Interface Map Rack Expansion Bus Capacity Online Access

Features:

  • The CPU joins rack processing with MPI, PROFIBUS DP, and PROFINET communication.
  • X1, X5, and the optional IF1 position serve different bus responsibilities.
  • Rack expansion and multicomputing increase station scope without combining the separate device-group limits.
Operating power arrives through the S7-400 backplane, and the processor occupies two slots in the rack.

Integrated and optional communication paths must be counted separately because each interface owns its own device group.

Online access combines STEP 7 engineering, clock synchronization, and read-only web information rather than browser-based control.

The Siemens 6ES7414-3EM05-0AB0 CPU 414-3 PN/DP Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the three interface positions are assigned

  • X1: The combined MPI/PROFIBUS DP interface operates at up to 12 Mbit/s.
  • X5: The two-port Ethernet interface supplies 100 Mbit/s PROFINET communication.
  • IF1: An IF 964-DP module can add another isolated PROFIBUS DP master or slave path.
  • Separation: The connectors are not interchangeable; each retains its documented bus role.

How the CPU fits into the S7-400 rack

  • Slot demand: The CPU occupies two rack slots.
  • Power path: Operating power comes from the S7-400 system power supply through the backplane.
  • Station growth: As many as 21 expansion units are documented for the system arrangement.
  • Multicomputing: UR1 or UR2 can contain as many as four CPUs in a multicomputing configuration.

How device limits are divided by bus

  • Integrated DP: The built-in PROFIBUS DP path supports up to 32 slaves.
  • Optional DP: The IF 964-DP path supports up to 96 slaves.
  • PROFINET: The IO-controller function supports up to 256 PROFINET devices.
  • Planning rule: Each maximum belongs to its own interface group and should not be combined into one common station count.

How engineering and online viewing are separated

  • Engineering baseline: STEP 7 V5.4 SP5 or later is listed for this CPU version.
  • Web access: The integrated web server is read-only and supports up to five HTTP clients.
  • Time service: Ethernet communication includes clock synchronization for the controller.
  • Device service: PROFINET supports device replacement without a swap medium while project editing remains a STEP 7 task.
Description
Siemens 6ES7414-3EM05-0AB0 is a CPU 414-3 PN/DP central processing unit for the SIMATIC S7-400 system, executing the control program while linking rack communication with MPI, PROFIBUS DP, and PROFINET.

Installed across two rack slots, 6ES7414-3EM05-0AB0 receives operating power from the S7-400 power supply through the backplane, so an independent 24 V feed is not part of the CPU connection.

Three interface positions give 6ES7414-3EM05-0AB0 separate bus duties: X1 carries MPI/PROFIBUS DP, X5 provides switched Ethernet/PROFINET, and IF1 accepts IF 964-DP when another isolated PROFIBUS path is required.

Station growth around 6ES7414-3EM05-0AB0 can extend through expansion units and a multicomputing arrangement, while the integrated and optional bus paths retain different device-group limits.

Engineering access to 6ES7414-3EM05-0AB0 starts with STEP 7 V5.4 SP5; its Ethernet services support clock synchronization and read-only web information rather than browser-based control or project editing.
