Computer Web Server (IIS)

 We have come a long way. The PLC program has been written. The primary visual program has been reported. Information is now being collected from the Do-more PLC via Modbus TCP and stored in a database using visual basic.
The next step is to deliver the information on the network. We will do this by installing Internet Information Services. (IIS) This is a group of internet servers that include a Web or Hypertext Transfer Protocol server (HTTP) and a File Transfer Protocol server (FTP). IIS will allow us to connect the physical hardware to the data. This could be desktop computers, laptops, tablets, cell phones, watches, etc. The advantage of using HTTP is that we can share information with all of these devices without being concerned about each of their operating systems. We are good to go as long as they can display a web page.


Active Service Pages (ASP) will be installed at the same time. This program will run scripts on the server before delivering the HTML code to the browser. It is similar to CGI and Perl but is simpler and faster.
ASP.Net Tutorial
We will install this on a Windows 8.1 machine.
Call up the Control Panel.
  • I was swiping in from the right and searching for “control panel.”
  • Win + x will call a menu to select the control panel.
IIS_000
Select Programs and Features
IIS_001
Select Turn Windows features on or off.
IIS_002
Select ASP after expanding Internet Information Services / World Wide Web Services / Application Development Features. This will select all of the other options.
IIS_003
Hit OK to install the services.
IIS_004
IIS_005
We now have IIS installed.
IIS_006
Under the following default directory, you will find the location to put your web pages.
C:\inetpub\wwwroot\
IIS_007
If you call up the iisstart.htm file in this directory, it will call up a page from Microsoft to explain the IIS web service.
IIS_009
Installing IIS on windows 7 and XP is similar to the above procedure. Windows 98, you had to install a personal web service (PWS) and then ASP separately.
Further information on ASP can be obtained from the following website:
This site will walk you through ASP.
Part 11 will look at HTML and scripting languages like JavaScript or VBScript.
