WebRelay Users Manual

      

Section 4:  Control Page

The WebRelay can be operated using a web browser, by sending text commands to an XML 
status/control page, and/or by sending Modbus/TCP requests. The WebRelay can be controlled using 
inputs, or other relays. (Using an input to control the relay was described in the previous sections of the 
manual, and will not be described here.)

4.1   Browser Operation (Standard Relay Mode)

Once the WebRelay is set up, users can access the 

Control Page

 using a web browser. Type the IP 

address of the WebRelay directly into the web browser address bar. For example, using the default IP 
address, the user would enter http://192.168.1.2. If the IP address is changed from the default, the user 
must use the new IP address. Note that if any port is used other than the default port 80, the port must 
also be included in the request. For example, accessing the unit at port 8000 would be as follows: 

http://192.168.1.2:8000

. The same is true when the default HTTPS port is changed.

The following screen with default settings appears when the Control Page is requested from the address
bar. The control page updates every three seconds.

The Control Page is normally what users see and use and it can be configured to fit your needs. The 

Control Page Setup

 tab has settings that determine if a specific resource is displayed or not displayed. 

The device title (text) is also specified in the 

Control Page Setup

 tab.

Header

Displays the text entered in the Main Header Text field on the 

Control Page Setup

 tab in the setup 

pages. This is usually a description of the application.

Input

This row displays the current state of the digital input. This row can be displayed (as shown) or not 
displayed by the settings in the 

Control Page Setup

 tab in the setup pages. The text in the left column is 

also specified in the Description field in the

 

Control Page Setup

 tab.

Relay

This rows displays the current state of the internal relay and allows the user to change relay state. The 
row can be displayed (as shown) or not displayed by the settings in the 

Control Page Setup

 

tab in the 

setup pages. The text in the left column (by default reads Relay Description) is also specified in the 

Xytronix Research & Design, Inc.
