        Overview Manuals Interface Roles Option-Module Logic Bus and Power Path Status and Installation

        Features:

        • Two independent SIMOLINK fiber-optic paths are available through X2/X3 and X4/X5.
        • The LE bus carries data between the expansion and FM 458-1 DP modules.
        • A MASTERDRIVES option connector is provided with a defined second-channel limitation.
        Siemens 6DD1607-0EA2 extends an FM 458-1 DP application module with two onboard SIMOLINK interfaces.

        The first and second optical pairs on 6DD1607-0EA2 can be assigned to master or slave communication according to the configured SIMOLINK network.

        When an option module occupies its carrier connector, 6DD1607-0EA2 automatically disables X4/X5 while retaining the first SIMOLINK path.

        The Siemens 6DD1607-0EA2 EXM 448-2 Communications Expansion Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Siemens 6DD1607-0EA2 EXM 448-2 Communications Expansion 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 two optical channels are assigned

        • First channel: X2 sends and X3 receives SIMOLINK optical data.
        • Second channel: X4 and X5 provide the equivalent transmit and receive path.
        • Master operation: A configured channel can coordinate a SIMOLINK ring with up to 200 MASTERDRIVES nodes.
        • Slave operation: The interface can instead provide fast coupling to SIMADYN D or another FM 458-1 DP.

        What changes when the carrier connector is occupied

        • Carrier function: The front connector accepts an additional MASTERDRIVES option module.
        • Channel consequence: Installing that option automatically disables the X4/X5 SIMOLINK interface.
        • Remaining path: X2/X3 continues as the available onboard optical channel.
        • Planning point: Port allocation must be decided before the option module and fiber routes are assigned.

        Separate routes for internal data and module supply

        • LE bus: This local expansion bus transfers data between 6DD1607-0EA2 and the FM 458-1 DP.
        • P bus: The parallel S7-400 backplane connection supplies power but is not the SIMOLINK data path.
        • Module supply: The expansion electronics operate from the 5 V backplane source.
        • Assembly order: The EXM module is joined to the FM 458-1 DP before the combined assembly enters the rack.

        Indicators and physical limits around the module

        • Green indication: The channel reports whether SIMOLINK network data traffic is present.
        • Red indication: The channel reports its interface power and operating condition.
        • Yellow indication: The module reports transfer status with the FM 458-1 DP basic unit.
        • Enclosure requirement: The open-type module belongs inside a closed cabinet or switch room.
        Description
        Siemens 6DD1607-0EA2 is the SIMATIC S7-400 EXM 448-2 communications expansion module for the FM 458-1 DP application module. Its role is to add SIMOLINK drive-bus communication while remaining mechanically and electrically part of the FM 458 module assembly.

        Two fiber-optic paths are built into 6DD1607-0EA2. X2 and X3 form the transmit and receive pair for the first SIMOLINK interface, while X4 and X5 form the second pair; either interface can participate in master or slave communication, and the master function can address as many as 200 MASTERDRIVES nodes.

        An additional MASTERDRIVES option module can be carried by 6DD1607-0EA2, but using that connector automatically removes the second SIMOLINK path from operation. Data exchanged with the FM 458-1 DP travels through the LE bus, whereas the SIMATIC P bus supplies the expansion module and does not carry its process communication.

        Each SIMOLINK channel on 6DD1607-0EA2 has green, red, and yellow status indication for network traffic, interface operation, and transfer with the basic unit. The module occupies one slot in the assembled S7-400 station, operates from the 5 V backplane supply, and is specified for a maximum ambient temperature of 40°C.

        Technical notes
        Siemens 6DD1607-0EA2 separates SIMOLINK fiber communication from LE-bus data exchange and P-bus power within an FM 458-1 DP assembly.

        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
        Why can the second SIMOLINK path disappear after 6DD1607-0EA2 is configured?
        On 6DD1607-0EA2, installing a MASTERDRIVES option module automatically disables the second X4/X5 SIMOLINK interface; X2/X3 remains available.
        Can 6DD1607-0EA2 operate as a standalone S7-400 communication card?
        No. 6DD1607-0EA2 is an expansion for the FM 458-1 DP and exchanges internal data with that basic module through the LE bus.
        What should be recorded before optical fibers are removed from 6DD1607-0EA2?
        Record the X2/X3 and X4/X5 routing, configured master or slave role, option-module presence, and LED states for 6DD1607-0EA2.
        How can an engineer separate a fiber problem from a host-transfer problem on 6DD1607-0EA2?
        The green and red indications on 6DD1607-0EA2 relate to the SIMOLINK channel, while the yellow indication reports transfer with the FM 458-1 DP.
        Does the SIMATIC P bus carry drive telegrams for 6DD1607-0EA2?
        No. The P bus supplies 6DD1607-0EA2, while LE-bus and SIMOLINK connections carry the internal and optical communication paths.
        What assembly check matters before 6DD1607-0EA2 is inserted into the rack?
        Confirm that 6DD1607-0EA2 is locked to the FM 458-1 DP, the rightmost LE-bus socket is covered, and the planned option combination uses no more than two expansions.
