        More Information

        Overview Manuals Input Logic DP Exchange Clock Backup Status Paths

        Features:

        • Keeps local input evaluation separate from PROFIBUS DP data exchange.
        • Supports equidistant PROFIBUS DP and direct device data exchange.
        • Retains operating data in backed SRAM alongside a hardware clock.
        The FM 458-1 DP module performs calculation and control work inside a SIMATIC S7-400 rack.

        Its local digital inputs remain separate from the PROFIBUS DP communication path used for distributed devices.

        Clock, backup and alarm functions provide timing, retention and status information around the control task.

        The Siemens 6DD1607-0AA2 FM 458-1 DP Application Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Siemens 6DD1607-0AA2 FM 458-1 DP Application Module 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.

        How the eight local inputs are interpreted

        • Connector X2: All eight digital input channels enter through this connector.
        • Logical 0: An input between -1 and +6 V is evaluated as the low state.
        • Logical 1: The high-state window extends from 13.5 to 33 V.
        • Transition time: A 0-to-1 change is accepted within 5 microseconds maximum.

        PROFIBUS services around the control task

        • Equidistance: The DP path can operate with timing linked to interrupt tasks.
        • Direct exchange: Slave-to-slave communication is supported without using the X2 inputs.
        • Distributed I/O: The interface connects remote I/O and drive data to module processing.
        • Separation: Optional interface modules provide galvanic separation where the input design requires it.

        Retained data and timekeeping

        • Stored context: SRAM retains the module data under backup.
        • Backup load: The battery circuit draws no more than 15 microamps.
        • Time base: The onboard real-time clock resolves 500 ms intervals.
        • Power boundary: The module accepts both the documented 5 V and 24 V DC supplies.

        Status and alarm handling

        • Alarm support: The module reports alarm events to the automation system.
        • Input state: Each channel is evaluated against the defined low and high voltage windows.
        • Bus state: DP communication status is distinct from the local X2 channel condition.
        • Retained state: Backed memory preserves stored data independently of the real-time clock resolution.
        Description
        Siemens 6DD1607-0AA2 is the FM 458-1 DP application module for the SIMATIC S7-400 platform. It performs arithmetic, closed-loop control and open-loop control tasks while providing a PROFIBUS DP path for distributed I/O and drives.

        Eight digital inputs enter 6DD1607-0AA2 through connector X2. The 24 V DC input circuit distinguishes a logical 0 from -1 to +6 V and a logical 1 from 13.5 to 33 V, with a maximum 0-to-1 delay of 5 microseconds.

        On the bus side, 6DD1607-0AA2 supports PROFIBUS DP equidistance and direct data exchange between devices. These services link time-coordinated communication and slave-to-slave transfers to the module's control workload without routing those signals through the eight local inputs.

        Backed SRAM and a real-time hardware clock preserve the module's stored operating context. For 6DD1607-0AA2, the clock has 500 ms resolution, the backup circuit draws no more than 15 microamps, and alarm capability supplies status information to the automation system.

        Technical notes
        Siemens 6DD1607-0AA2 combines eight fast 24 V digital inputs, PROFIBUS DP services, backed SRAM and a hardware clock for S7-400 control tasks.
