Unitronics Web Server Demo
This page shows different options for Web pages that you can create and host on Unitronics PLCs.
You do this by using the VisiLogic application Enhanced PLC Webserver.vlp.
Exact instructions on how to create a PLC Webserver application are in the document Enhanced PLC WebServer.pdf
You can view operand values as shown in the table below. The Example column shows actual PLC operand values. If you are now viewing this page from your PLC's SD card, you can enter Online Test Mode, write operand values, and refresh the page to see them change.
Supported Operand Type |

Example |
MI - Memory Integer SI - System Integer DW - Double Word |
You can display register values from within your PLC.
You can define the display format, including decimal point location and leading spaces options. |
MI0 = [MI0,3,0,0] SI30 = [SI30,0,0,0] DW5 = [DW5,0,0,2] |
MB - Memory Bit XB - Toggle Bit IB - Input BitOB - Output Bit |
You can assign text descriptions to show the status of a binary value. |
MB1 = [MB1,Bit is OFF,Bit is ON] O2 = [OB2,Motor Idle,Motor Running] |
TD - Timer | Show PLC Timers of all types and formats. |
T50 = [TD50,7,C,R] |
ST - String from String Library | Display direct and indirect Strings from the PLC's String Library. |
String 0 = [ST0,PPPPPPPPPPP] |
You can also write operand values.
The field below is linked to ML12. Enter a value and press Send Data to write it to the PLC and display the result.
Result:
Unformatted: [ML12,0,0,0]
With decimal point: [ML12,2,0,0]
In hexadecimal: [ML12,0,3,0]

For example - click on the following link to download a .udt file from the PLC to your computer hard drive:
You can also download any other type of file from the PLC SD card, such as .doc , .pdf, etc.
Download a .pdf file from PLC SD card
To download files from other websites, include a link for file download from a URL (web site or IP). For example, you can download a "User Manual" from a manufacturer via PLC web server.
Images can be shown via a link to a web site or IP address. For example, the Unitronics Logo below is hosted on the Unitronics .ftp site.
You can show an image that is stored on the SD card. The image of the V350 below is from the SD card in your PLC.
You can also use images to create hyperlinked buttons as shown below.
