        More Information

        Overview Manuals Channel Signals Measurement Modes Output Response Front Connector

        Features:

        • Eight hardware channels execute counting and measurement functions.
        • Channel inputs accept the documented 24 V or NAMUR signal path.
        • Assigned digital outputs can respond to configured count or dosing conditions.
        Pulse processing occurs in the function module rather than inside the normal CPU scan.

        Gate inputs determine when each configured measurement is enabled.

        The S7-300 backplane carries parameters, results and diagnostic information to the controller.

        The Siemens 6ES7350-2AH01-0AE0 SIMATIC S7-300 FM 350-2 Counter Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Matching every counter channel to its pulse source

        • 24 V input: The channel accepts the documented 24 V encoder or pulse signal.
        • NAMUR input: The alternate sensor path uses its dedicated low-voltage supply.
        • Gate signal: A separate input controls when the measurement is active.
        • Shielding: Cable shields and reference conductors follow the assigned front-connector pins.

        Turning pulse sequences into the required process value

        • Counting: The module accumulates events in the selected direction and range.
        • Frequency: Pulse rate is converted into a frequency result.
        • Speed and period: Configured scaling relates pulse timing to motion or elapsed time.
        • Dosing: Comparison values coordinate counting with an assigned output response.

        Linking local counter conditions to field outputs

        • Eight outputs: One set of digital outputs is available to the configured channels.
        • Comparison action: Threshold events can change an output without a separate PLC scan.
        • Load path: Each output switches its documented 24 V field load.
        • CPU supervision: The controller reads status and can adjust the configured parameters.

        Preserving the wiring boundary at the 40-pole connector

        • Channel pins: Pulse, NAMUR and gate inputs occupy defined connector positions.
        • Supply references: Sensor and output circuits use the assigned voltage and common terminals.
        • Cable identification: Every conductor should retain its channel and function label.
        • Commissioning test: Known pulses and gate states confirm scaling before process use.
        Description
        Siemens 6ES7350-2AH01-0AE0 is a SIMATIC S7-300 FM 350-2 counter module that performs eight-channel counting, frequency, speed, period and dosing functions outside the normal CPU scan. It converts incoming pulse sequences into count or measurement values that the S7-300 program can read and supervise.

        Each channel of 6ES7350-2AH01-0AE0 is configured for either the documented 24 V pulse path or its NAMUR sensor input, while gate signals define when counting is active. This organization lets the module distinguish the measured pulse stream from the control signal that starts, stops or qualifies the measurement.

        Eight digital outputs on 6ES7350-2AH01-0AE0 can react to configured comparison or dosing conditions without waiting for a separate PLC output update. The S7-300 CPU still exchanges parameters, results and diagnostic data with the module over the backplane, linking fast local counter behavior to the wider control program.

        Field wiring for 6ES7350-2AH01-0AE0 terminates at the 40-pole front connector, where channel inputs, gates, outputs and supply references are assigned to defined pins. Encoder type, shield routing and group commons must therefore follow the channel configuration before measured values are trusted.

        Technical notes
        With Siemens 6ES7350-2AH01-0AE0, set each channel for its connected 24 V encoder or NAMUR sensor and verify the assigned gate and output wiring before enabling the count function.

        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
        How should the input type be selected for Siemens 6ES7350-2AH01-0AE0?
        Configure each Siemens 6ES7350-2AH01-0AE0 channel for the connected 24 V encoder or NAMUR sensor; the two input paths are not interchangeable.
        Why can 6ES7350-2AH01-0AE0 react faster than a counter implemented in the PLC program?
        The counting hardware in 6ES7350-2AH01-0AE0 processes pulses and comparison events locally instead of waiting for every normal CPU scan.
        What should be checked when a channel on 6ES7350-2AH01-0AE0 never starts counting?
        For 6ES7350-2AH01-0AE0, verify the gate state, selected input path, sensor supply, reference conductor and channel parameter set.
        Can the digital outputs of 6ES7350-2AH01-0AE0 drive any load directly?
        No. Each 6ES7350-2AH01-0AE0 output is limited to the documented 24 V switching path and current rating, so the connected load and protection must remain within those limits.
        How does 6ES7350-2AH01-0AE0 report counter values to the S7-300 CPU?
        The S7-300 backplane transfers parameters, measured values, status and diagnostics between 6ES7350-2AH01-0AE0 and the controller program.
        Which records reduce rewiring errors when replacing 6ES7350-2AH01-0AE0?
        Keep the channel parameter set and a pin-by-pin front-connector record for 6ES7350-2AH01-0AE0, including encoder type, gate input, output load and shield termination.
