More Information

Overview Manuals Memory Retention Network Topology IO Controller Scope Rack and Engineering

Features:

  • Program and data each receive 5.6 MB within the CPU's 11.2 MB work memory.
  • MPI/DP and switched PROFINET are integrated as separate communication paths.
  • A plug-in IF 964-DP can add a third isolated PROFIBUS relationship.
Siemens 6ES7416-3ER05-0AB0 executes the S7-400 application while coordinating fieldbus and Ethernet data through distinct interfaces.

Its memory layout separates active program and process data from the card-based load-memory store.

The optional interface position lets 6ES7416-3ER05-0AB0 add another DP segment without converting either integrated PROFINET port.

The Siemens 6ES7416-3ER05-0AB0 CPU 416-3 PN/DP may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6ES7416-3ER05-0AB0 CPU 416-3 PN/DP 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.

Active memory and card storage follow different paths

  • Program area: 5.6 MB of work memory holds executable control code.
  • Data area: A separate 5.6 MB region holds the active process and block data.
  • Load store: FLASH or RAM cards extend load memory without enlarging either work-memory region.
  • Backup behavior: Battery backup retains all work memory and an installed RAM card; FLASH does not depend on that retention path.

Three interface positions create separate network roles

  • MPI/DP interface: The first RS485 port supports programming, operator, S7, and PROFIBUS relationships.
  • PROFINET switch: Two RJ45 ports belong to one integrated Ethernet interface and forward network traffic through the CPU.
  • Optional DP path: IF 964-DP adds another PROFIBUS master or device segment at the third interface position.
  • Routing: Projected S7 routing connects supported engineering and communication paths across the assigned interfaces.

How the integrated Ethernet path manages distributed IO

  • Controller role: The PROFINET interface operates as an IO controller rather than an IO device.
  • Device set: As many as 256 PROFINET IO devices can be projected within the documented address and timing limits.
  • Startup handling: Prioritized startup and device activation or deactivation are supported for configured IO devices.
  • Replacement function: Device replacement without removable media applies to supported PROFINET IO devices managed by the controller.

CPU hardware, software, and rack resources must agree

  • Rack space: The processor occupies two S7-400 slots and receives supply through the backplane.
  • Engineering baseline: Firmware V5.3 is paired with STEP 7 V5.4 SP5 or a supported later release.
  • Optional hardware: The IF 964-DP must appear in the hardware configuration before its third-interface resources are available.
  • Diagnostics: The CPU diagnostic buffer can retain up to 3,200 entries for projected and runtime events.
Description
Siemens 6ES7416-3ER05-0AB0 is the SIMATIC S7-400 CPU 416-3 PN/DP central processing unit. It executes the automation program and coordinates S7-400 process data through an MPI/PROFIBUS DP interface, an integrated PROFINET interface, and a position for a plug-in IF 964-DP module.

Working data in 6ES7416-3ER05-0AB0 is divided into 5.6 MB for the program and 5.6 MB for data. A FLASH or RAM memory card expands load memory to 64 MB, while battery backup retains the working and RAM-card contents under the documented backup conditions.

The first communication path on 6ES7416-3ER05-0AB0 can serve MPI, PROFIBUS DP master, or PROFIBUS DP device operation at up to 12 Mbit/s. The second path is a two-port 100 Mbit/s PROFINET switch for IO-controller, S7, web-server read, and open Ethernet communication, keeping Ethernet devices separate from the first DP segment.

A third network role becomes available on 6ES7416-3ER05-0AB0 only after the IF 964-DP interface module is installed. That plug-in path provides another isolated PROFIBUS DP master or device connection, so its configured stations, addresses, and interface current belong to the optional module rather than the built-in PROFINET ports.

Backplane power from the S7-400 system supply operates 6ES7416-3ER05-0AB0, which occupies two rack slots and dissipates 6 W typically. STEP 7 V5.4 SP5 is the listed engineering baseline for firmware V5.3, and the hardware catalog, memory card, interface module, and network project must match that CPU version.

Technical notes
Siemens 6ES7416-3ER05-0AB0 divides controller traffic among MPI/DP, switched PROFINET, and an optional IF 964-DP while retaining separate program and data memory.

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.
Why can PROFINET devices communicate while a PROFIBUS segment on 6ES7416-3ER05-0AB0 remains unavailable?
The 6ES7416-3ER05-0AB0 uses separate interface configurations, so a working PROFINET switch does not confirm the MPI/DP or optional IF 964-DP address, wiring, or master assignment.
What must be present before the third interface of 6ES7416-3ER05-0AB0 can be commissioned?
The 6ES7416-3ER05-0AB0 needs the supported IF 964-DP plug-in module installed and represented in the STEP 7 hardware configuration before that DP path exists.
How should memory contents be handled before power is removed from 6ES7416-3ER05-0AB0?
Identify whether 6ES7416-3ER05-0AB0 uses FLASH or RAM card load memory, preserve the STEP 7 project, and verify the backup battery condition for retained work and RAM-card data.
Why are the two RJ45 connectors on 6ES7416-3ER05-0AB0 not configured as two independent CPUs interfaces?
Both RJ45 ports on 6ES7416-3ER05-0AB0 belong to the same integrated PROFINET interface and two-port switch, so they share its controller role and network configuration.
What should be compared if a replacement 6ES7416-3ER05-0AB0 rejects the existing hardware project?
Compare the 6ES7416-3ER05-0AB0 order number, hardware functional status, firmware V5.3, STEP 7 catalog entry, memory card, and optional IF module against the saved project.
Where should diagnosis begin when distributed IO startup is incomplete on 6ES7416-3ER05-0AB0?
Read the 6ES7416-3ER05-0AB0 diagnostic buffer, identify whether the station belongs to PROFINET or either DP path, then check that interface’s topology, address, and configured device state.
