        More Information

        Overview Manuals Counter Logic Compare Results Project Fit Applications

        Features:

        • Four counter paths: Multiple pulse sources can be processed without sharing one accumulated value.
        • Two comparisons per counter: Each channel can signal two independent count thresholds.
        • PLC-visible results: Match states are available through documented DM and buffer-memory locations.
        KV-MX1 is a dedicated KEYENCE counter module used when pulse capture and threshold comparison must occur outside normal input scanning.

        Its most clearly documented software boundary is the eight comparator-result bits: two for each of four counters.

        The module remains application-specific because counter mode, pulse source, reset logic and threshold values are defined by the PLC project.

        Apter Power can help confirm KEYENCE KV-MX1 module identity, PLC fit, counter-channel plan and comparator-address use before quotation.

        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.
        • Four channels: Each counter retains its own accumulated value and operating logic.
        • Pulse processing: Dedicated hardware handles signals that can be faster than ordinary PLC scans.
        • Reset and gate: Project logic defines when each channel counts, holds or returns to a reference.
        • Application scaling: Counts become distance, speed or quantity through machine-specific conversion.
        • Two matches each: Comparator 0 and comparator 1 are available for every counter.
        • Eight active bits: Counters 1 through 4 use result bits 0 through 7.
        • Reserved upper bits: Bits 8 through 15 are not assigned to comparator results.
        • Decision use: Ladder logic can act on a threshold while keeping final output interlocks in the PLC program.
        • Memory mapping: The module start DM and buffer-memory addresses must match the project.
        • Module position: Moving the card can change how its assigned data is referenced.
        • Signal definition: Pulse, direction, gate and reset wiring are preserved from the machine drawing.
        • Controlled proof: A known pulse count is used to verify accumulation and both match points.
        • Cut-to-length machines: Compares encoder counts with process-length thresholds.
        • Indexing equipment: Generates PLC decisions at repeatable count positions.
        • Speed monitoring: Converts pulse accumulation over time into a machine-speed check.
        • Production counting: Tracks fast sensor events while the main PLC scan manages sequence logic.
        Description
        KV-MX1 expands a compatible KEYENCE PLC with dedicated counter processing for pulse signals that must be evaluated independently of ordinary scanned inputs. Four counters give the control program separate measurement paths for position, length, speed or event-count tasks.

        KV-MX1 provides two comparator-match results for each counter. Those results are exposed through the documented data-memory and buffer-memory locations, allowing the PLC program to turn count thresholds into machine decisions without repeatedly reconstructing the comparison in ladder logic.
        Alternative Names
        KVMX1
        Technical notes
        KV-MX1 reserves bits 8 through 15 of its comparator-result word; they are not spare threshold flags. Logic that assigns those bits can create undefined decisions after software or module changes. Use only bits 0 through 7 for documented comparator results, and implement additional thresholds in supported PLC logic instead of repurposing the reserved range.

        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
        A cut-to-length machine needs separate slow-down and cut decisions from one encoder. Can KV-MX1 provide both?
        Yes. Assign the two comparator matches of the selected counter to the two process thresholds, then let the PLC sequence and safety interlocks control the physical outputs.
        After moving KV-MX1 to another PLC position, why can counts update while the old comparator addresses stop working?
        The result mapping follows the module start allocation. Update the project references to the new start DM plus 260 or buffer address 1136 before diagnosing the pulse input.
        A KV-MX1 count runs in the wrong direction after maintenance. Where should diagnosis begin?
        Start with the direction signal and the selected counter mode. Prove their state at the module before changing scaling or comparator values, because those settings cannot correct an inverted count direction.
        A KV-MX1 counter changes but its compare result never turns on. What should be checked?
        Check the comparator value, selected counter, result-bit address, count direction, reset state and whether the program is reading the correct module start DM.
        What should be recorded before replacing KV-MX1?
        Record PLC and module position, pulse wiring, counter modes, scaling, reset and gate logic, comparator values, data-memory mapping and any output interlocks that use the results.
        How should KV-MX1 be tested before machine outputs are enabled?
        Apply a known pulse count at controlled speed, prove reset and direction, cross both comparator thresholds, and verify only the intended PLC result bits change.
