When using Wonderware Information Server's Factory Alarms page, there is a bug in the Historical Alarms page preventing you from seeing alarms that have occurred after 2015. This tech note describes how to fix this issue.

This issue is caused by the year selection dropdown being hard coded to list the years 1995 through 2015. Because Information Server's interface is made through ASP webpages, this is a setting which we are able to modify.
Note 1: If you are using a recent version of the software, there may be a hotfix available to fix this issue for you.
Note 2: This fix involves manually editing files on the system. If you ever upgrade your software, this fix may be lost.
Step 1: On your hard drive, go to the folder where the Wonderware Information Server website is installed.
By default this will be: C:\inetpub\wwwroot\Wonderware
Step 2: We need to modify the file specifically related to the Historical Alarms display. To find this, go into the Applications folder, and then the Alarms folder.
By default this will be: C:\inetpub\wwwroot\Wonderware\Applications\Alarms
Step 3: Find the file named configure.asp. This is the file we will be modifying. Before making any changes, backup this file by copying and pasting into the same folder, and give it a name such as "configure.asp_backupBeforeDateChange".
Step 4: Open the file in Windows Notepad, or another text editor.
Step 5: We need to find the section in the file that contains the date. Go to Edit > Find, and search for "2015". You should find a section that looks like the following. We can see the the dates presented in the software come from the line highlighted in yellow:
Step 6: Edit the available dates as you see appropriate. In the following example I have set the ending date range to be the year 2025, instead of the default 2015:
Step 7: Save the file.
Step 8: Open a new webbrowser and look at the Factory Alarms. You should now be able to select a year beyond 2015.
