Overview

The VHSC module is designed for high-speed counting in industrial applications. It functions as an intelligent block transfer I/O module, allowing seamless signal interfacing with any Allen-Bradley programmable controller that supports block transfer. Through block transfer programming, the module's status data is efficiently transferred from its memory to a specified location in the processor's data table. Additionally, configuration words are transferred from the processor's data table back to the module's memory, ensuring smooth and precise operation.
