Section 1: Introduction

WebRelay-10 Plus™ is a robust, 10-relay module with a built-in web server. It can be controlled and/or monitored
over any IP network including private networks, IP-based industrial control networks, and the Internet. Users can
operate WebRelay-10 Plus™ using a web browser or a custom application. Computers, PLCs, or automation
controllers may control and monitor WebRelay-10 Plus™ without user intervention. This works by sending text
commands over the network and reading XML status pages from WebRelay-10 Plus™, or by using Modbus/TCP
protocol.
