        Overview Manuals Socket Pinout Sensor Supply Fault Reporting Parameter Set

        Features:

        • Siemens 6ES7141-1BF40-0AB0 is an ET 200X BM141 ECOFAST basic module with eight 24 V DC digital inputs.
        • Each X1–X8 M12 socket pairs its input channel with an electronically protected sensor-supply output.
        • Short-circuit, wire-break and edge-event functions are handled per channel.
        The RS485 PROFIBUS-DP connection places 6ES7141-1BF40-0AB0 on the ET 200X backplane, where input states and diagnostic events are transferred to the controller.

        Input delay is selected for the complete 6ES7141-1BF40-0AB0 module, but short-circuit, wire-break, rising-edge and falling-edge events remain associated with the affected channel.

        Protection at the field side depends on fitting the specified caps to unused sockets and keeping the sensor cable within 30 m. Those limits preserve the enclosure boundary without changing the PROFIBUS data path.

        The Siemens 6ES7141-1BF40-0AB0 ET 200X BM141 ECOFAST Diagnostic Basic Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

        M12 Channel Layout

        • Socket range: 6ES7141-1BF40-0AB0 assigns the eight inputs to X1–X8 M12 sockets.
        • Pin format: Each field connection uses a 5-pin M12 socket.
        • Sensor path: The sockets connect the documented switch and proximity-sensor types.
        • Unused ports: Unused sockets require the documented caps for the stated enclosure protection.

        One Protected Supply Path per Socket

        • Output count: 6ES7141-1BF40-0AB0 provides eight sensor-supply outputs, one for each X1–X8 socket.
        • Protection: Each sensor-supply output is electronically protected against short circuit.
        • Input-current value: The documented 10 mA value is the typical input current at signal state 1, not the sensor-supply capacity.
        • Sensor wiring: The M12 connections accept switches and 2-, 3-, or 4-wire proximity sensors within the documented pin assignment.

        Diagnostic Handling

        • Module diagnostics: 6ES7141-1BF40-0AB0 provides configurable module diagnostics.
        • Interrupt setting: Diagnostic interrupts are configurable for the module.
        • Status indication: Sensor-supply indicators and the red SF group-error LED expose fault status.
        • Backplane path: Fault information is transferred through the PROFIBUS DP backplane connection.

        Input Behaviour

        • Input standard: 6ES7141-1BF40-0AB0 uses IEC 61131 Type 2 input characteristics.
        • Delay setting: Input delay can be configured for the complete module.
        • Bus rate: The PROFIBUS DP path supports the documented 9.6 kbit/s to 12 Mbit/s range.
        • Cable boundary: The field cable length is limited to the stated 30 m value.
        Description
        The Siemens 6ES7141-1BF40-0AB0 is an ET 200X BM141 ECOFAST diagnostic basic module that brings eight 24 V DC digital input channels into a distributed PROFIBUS-DP station. It passes the field states and channel diagnostics from the M12 connections to the station backplane.

        Across X1 through X8, 6ES7141-1BF40-0AB0 assigns one digital input and one electronically protected sensor-supply output to each M12 socket. Switches and 2-, 3-, or 4-wire proximity sensors therefore connect through individually identified field ports rather than through two eight-channel supply groups.

        For each channel, 6ES7141-1BF40-0AB0 can report short circuit and wire break and can generate process interrupts on rising or falling edges. Input delay is parameterized for the complete module, while the diagnostic and edge events remain channel-specific.

        Unused sockets on 6ES7141-1BF40-0AB0 require the documented caps to maintain the stated IP65, IP66, and IP67 enclosure protection. The 30 m field-cable limit applies to the sensor connection, keeping the field wiring boundary separate from the PROFIBUS backplane path.
        Technical notes
        Siemens 6ES7141-1BF40-0AB0 provides eight 24 V DC digital inputs through X1–X8 M12 sockets with configurable delay and diagnostics.

        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
        How should the eight field channels be assigned to Siemens 6ES7141-1BF40-0AB0?
        Assign the eight 24 V DC inputs to the X1–X8 M12 five-pin sockets on 6ES7141-1BF40-0AB0 and verify each field conductor against its intended channel.
        Which sensor wiring types can Siemens 6ES7141-1BF40-0AB0 accept?
        Use switches or 2-, 3-, and 4-wire proximity switches with 6ES7141-1BF40-0AB0; confirm the sensor type before selecting the field cable.
        Why should 10 mA not be treated as sensor-supply capacity on Siemens 6ES7141-1BF40-0AB0?
        On Siemens 6ES7141-1BF40-0AB0, 10 mA is the typical input current at signal state 1; each M12 socket has a separately protected sensor-supply output.
        How can a commissioning engineer distinguish a sensor-supply issue on Siemens 6ES7141-1BF40-0AB0?
        Use the supply indicators, red SF group-error LED, configurable diagnostics, and diagnostic interrupts of 6ES7141-1BF40-0AB0 to separate supply and module faults.
        What input timing setting is available on Siemens 6ES7141-1BF40-0AB0 when field signals need filtering?
        Input delay on 6ES7141-1BF40-0AB0 is configured for the complete module rather than per channel, so set it against the station-wide signal requirement.
        What installation limits should be checked for unused sockets and field cable on Siemens 6ES7141-1BF40-0AB0?
        Fit the documented caps to unused sockets and keep the field cable within 30 m for 6ES7141-1BF40-0AB0 when maintaining the stated protection boundary.
