        Overview Manuals Memory Retention PROFIBUS Topology Rack Expansion Runtime Diagnostics

        Features:

        • Divides 11.2 MB of integrated work memory equally between code and data.
        • Provides two integrated MPI/PROFIBUS paths plus a third plug-in IF 964-DP position.
        • Supports battery-backed controller data and memory-card expansion up to 64 MB.
        The first integrated interface can operate as MPI or PROFIBUS DP, while the second is dedicated to PROFIBUS DP master or slave operation.

        An IF 964-DP module can extend the CPU with a third PROFIBUS interface using the same operating model as the second link.

        The CPU combines large block capacity, extensive diagnostic buffering, and multiple S7 communication resources for an S7-400 rack.

        Choosing How the Load-Memory Image Survives Power Loss

        • Working program: Code and controller data execute from their separate work-memory areas after the project is loaded.
        • RAM load memory: A RAM card expands load memory but remains part of the battery-backed retention arrangement.
        • FLASH load memory: A FLASH card stores the load-memory image without relying on the RAM backup path.
        • Selection effect: The chosen card type changes retention behavior and service procedure, not the CPU's processing interfaces.

        Dividing Programming, DP, and Optional Bus Segments

        • First connector: The first RS-485 interface can support MPI communication or operate as a PROFIBUS DP channel.
        • Second connector: The second integrated interface forms an independent PROFIBUS DP master or slave segment.
        • Optional connector: An IF 964-DP adds a third DP path without replacing either integrated interface.
        • Project mapping: Each physical bus must be assigned to its corresponding interface in the STEP 7 hardware configuration.

        Extending the Central S7-400 Station

        • Central placement: The CPU occupies two slots in the central rack and manages the station from that rack position.
        • Expansion units: Interface modules link the central rack to the permitted expansion units rather than extending the backplane without a boundary.
        • Multi-CPU layout: The supported number of CPUs depends on whether the central rack is UR1, UR2, or CR3.
        • Commissioning check: Rack type, slot position, and interface-module arrangement must match the saved hardware project before startup.

        Connecting Stored Events with Live Controller State

        • Event history: The diagnostic buffer retains controller and communication events for later review.
        • Live variables: Status and modify functions compare current process values with the behavior expected by the user program.
        • Controlled testing: Force resources can hold selected variables for a defined commissioning test without rewriting program logic.
        • Message context: Process-control and block-related messages help relate a reported event to the responsible program or communication resource.
        Description
        At the center of an S7-400 rack, Siemens 6ES7416-3XR05-0AB0 operates as the SIMATIC CPU 416-3 central processing unit. It executes the station program, maintains controller data, and supplies the integrated communication resources used by programming devices, operator stations, and distributed I/O.

        The 11.2 MB work-memory structure of 6ES7416-3XR05-0AB0 is split evenly between 5.6 MB for code and 5.6 MB for data. Integrated load memory provides 1 MB of RAM, while RAM or FLASH memory cards can extend the load-memory space to 64 MB according to the required storage behavior.

        Field communication is distributed across the interfaces of 6ES7416-3XR05-0AB0. The first integrated RS-485 connection can serve MPI or PROFIBUS DP, the second provides another PROFIBUS DP master/slave channel, and the plug-in IF 964-DP position can add a third DP interface.

        Controller supervision in 6ES7416-3XR05-0AB0 includes a programmable diagnostic buffer, status and force functions, message handling, and time synchronization. These services work with the rack and network configuration rather than duplicating the user-program memory path.

        Technical notes
        Siemens 6ES7416-3XR05-0AB0 combines two integrated PROFIBUS-capable interfaces with an IF 964-DP expansion position and requires STEP 7 V5.3 SP2 plus the documented hardware update.

        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.
        VIEW ALL FAQS
        What should be verified before replacing an earlier CPU 416-3 with 6ES7416-3XR05-0AB0?
        Check the complete 6ES7416-3XR05-0AB0 order number, firmware support, STEP 7 level, memory requirement, and interface use against the existing S7-400 project.
        How should the first and second PROFIBUS-capable interfaces of 6ES7416-3XR05-0AB0 be assigned?
        The first interface of 6ES7416-3XR05-0AB0 can serve MPI or PROFIBUS DP, while the second is the dedicated additional PROFIBUS DP channel.
        What hardware is required when 6ES7416-3XR05-0AB0 needs a third PROFIBUS DP path?
        Install an IF 964-DP in the third interface position of 6ES7416-3XR05-0AB0 and include that interface in the STEP 7 hardware configuration.
        Which memory-card type suits a project that must retain load memory without battery support on 6ES7416-3XR05-0AB0?
        Use the documented FLASH memory-card option for nonvolatile load memory on 6ES7416-3XR05-0AB0; RAM load memory depends on the controller's backup arrangement.
        What rack constraint matters when 6ES7416-3XR05-0AB0 is used in a multi-CPU S7-400 station?
        The permitted CPU count depends on the selected central rack, so the 6ES7416-3XR05-0AB0 project must match the documented UR1, UR2, or CR3 arrangement.
        How can intermittent controller faults be reviewed after they occur on 6ES7416-3XR05-0AB0?
        Use the diagnostic buffer of 6ES7416-3XR05-0AB0 to review stored events, then relate the entries to status, force, and communication diagnostics in STEP 7.
