Product Overview

The Keyence KV Ethernet driver works in conjunction with KEPServerEX to provide a seamless, secure, and reliable data exchange between client applications and KEYENCE KV series PLCs using the Host Link communications protocol over both the TCP and UDP transport layers.

With the Keyence KV Ethernet driver, KEPServerEX provides real-time read/write connectivity between KEYENCE KV series PLCs and diverse devices and software applications, including OPC clients and IoT solutions.

The Keyence KV Ethernet driver is localized in Japanese for enhanced accessibility, productivity, and safety for Japanese-speaking users.
