        Overview Manuals Counters Gate & Outputs Modes FM Alarms

        Features:

        • Eight hardware counters process encoder events outside the cyclic input image.
        • Gate inputs and switching outputs connect counter conditions to the field process.
        • Counting, frequency, speed, period, and proportioning modes use one module platform.
        Siemens 6ES7350-2AH00-0AE0 acquires eight counter channels and transfers results to the S7-300 CPU.

        Supported encoders on 6ES7350-2AH00-0AE0 use the assigned 24 V or NAMUR input path.

        Parameterized interrupts from 6ES7350-2AH00-0AE0 report configured events and diagnostic conditions.

All prices are shown in USD.

        Counter Input Processing

        • Channels: Eight hardware counters retain events independently of the normal CPU scan.
        • Signal level: The selected 24 V or NAMUR input mode must match the connected encoder.
        • Count range: Each channel uses a 32-bit or signed 31-bit value according to its configuration.
        • Frequency: The encoder type and signal form determine the usable limit up to the documented 20 kHz maximum.

        Process Control Connections

        • Gate inputs: One digital input per counter supplies the configured gate start or stop action.
        • Switching outputs: Eight protected outputs can react to assigned counter or measurement conditions.
        • Group load: Mounting orientation and ambient temperature set the permitted total output current.
        • Inductive loads: The much lower inductive switching limit must be observed for coils and contactors.

        Counting and Measurement Functions

        • Counting: Pulse accumulation uses the configured direction and gate behavior.
        • Frequency: Measured pulse rate is calculated over the assigned measurement interval.
        • Speed and period: Encoder timing supports speed and period-duration results.
        • Proportioning: The configured function relates counted events to the assigned output behavior.

        Interrupts and Fault Isolation

        • Group fault: The red SF indicator directs troubleshooting to readable module diagnostics.
        • Diagnostic interrupt: A parameterized diagnostic alarm reports configured fault conditions to the CPU.
        • Hardware interrupt: Counter events can trigger a parameterized hardware interrupt.
        • Commissioning: Test the encoder, gate, count direction, output reaction, and interrupt handling as one channel chain.
        Description
        Siemens 6ES7350-2AH00-0AE0 is a SIMATIC S7-300 FM 350-2 counter module with eight 24 V counting channels. It processes encoder pulses independently of the normal CPU input scan and returns counts, measured values, status, and diagnostics through the S7-300 backplane.

        Each counter on 6ES7350-2AH00-0AE0 accepts supported 24 V incremental, directional, proximity, NAMUR, or two-wire sensor signals. Eight digital inputs provide gate start or stop functions, while the module supplies the documented NAMUR voltage path and protects that supply against short circuit.

        The eight digital outputs of 6ES7350-2AH00-0AE0 can react to configured counter conditions without waiting for a separate output module. Their group-current limit changes with mounting orientation and ambient temperature, so output loads and installation position must be evaluated together.

        Configured modes on 6ES7350-2AH00-0AE0 cover counting, frequency measurement, speed measurement, period measurement, and proportioning. Parameterizable diagnostic and hardware interrupts allow the CPU program to react to module faults or configured counter events.
