Function

High-speed precise counting: It achieves precise counting for high-frequency pulse signals, supporting encoder phase decoding and ordinary pulse counting, meeting the position/quantity statistics requirements in high-speed motion scenarios

Flexible counting mode: The counting type, frequency doubling coefficient, and counting direction can be configured through the Step7 software to adapt to different sensor signal types

Hardware-triggered control: Supports hardware reset/set function, which can quickly reset the count value or set the initial value through external signals, improving the control response speed

Counting trigger output: Integrated digital output, with preset counting thresholds. When the count reaches the set value, the output is automatically triggered to achieve interlocking control between the count and the actuator

Fault diagnosis and status feedback: It is equipped with fault alarm functions such as input signal loss, power failure, and count overflow. The module status and count data are uploaded to the CPU in real time, facilitating remote monitoring and fault detection

Parametric configuration: No hardware jumpers are required. Parameters such as counting mode, threshold, and input/output types can be configured through the Step7 software. Parameter backup and batch replication are supported

Application scenarios

Production count statistics: Counting the output of products on the assembly line and statistics on the quantity of parts processed

Position positioning control: Precise positioning of the equipment is achieved through encoder signal counting

Speed detection calculation: Based on the number of counting pulses per unit time, parameters such as motor speed and conveyor belt speed are indirectly calculated

Material metering control: Flow metering of powder/liquid materials, counting control of material filling volume in packaging machines

Automated equipment linkage: For instance, the sorter triggers the sorting action based on the counting signal, and the palletizer initiates the palletizing process when the counting meets the standard

Machine tools and processing equipment: Counting of cutting times for small machine tools and counting of tool life
