Problem Statement
This article describes a solution to fix the AspenWatch Menu display on the APC Web Viewer
Solution
In Version 12 a new APC Web Viewer was released as a new interface to Operate DMC3 Controllers. This new APC Web Viewer is installed with the default installation of the Web Server (PCWS). The APC Web Viewer has the capability to display the AW Menu in a similar way as PCWS does. And it will the same configuration as PCWS (ADSA Configuration).
One of the problems that may happen is that APC Web Viewer may fail to display the AspenWatch Menu. If that is the case, there are multiple things that can be checked to fix this problem:
1.- Verify that AW service is running and IP21 Manager is running. This will happen, AW Maker, as well-meaning Controller and Tags collecting and is always a good practice to make sure all components are working properly.
2.- Make sure the Controllers are collecting and show Success Status. Checking the Controller status help to check if the collecting is executing properly.
3.- Make sure PCWS can display the AW information. If ADSA is properly set up and AW is collecting data, then is expected that PCWS display all AW information. Not only the AW Menu, but the History tab should also display all information. If PCWS fails to display AW information, it would be expected APC Web Viewer fail too. One quick trick to refresh the AW data is to click on the History tab and go back to the Online Tab.
4.- Make sure the Page is added to the trusted sites. Security could be another problem with the AW Data from the web viewer.
5.- Finally we have encountered that is possible that Microsoft and Aspen updates could cause some issues. If that is the case for V12.1 we suggest applying CP1 Patch and EP3 Patch for Web Viewer

EP3

6.- IP21 SQL Security. Another issue that could appear is that SQL security is not properly set in IP21 Manager. In this case, we can suggest two things:
Apply MES cumulative Patch for V12.1. this patch contains some important fixes related to SQL and IP21. So, in order to have an updated server and fixed the problem, we suggest applying this patch.

If you don’t want to install the patch another thing to try is to change the security settings of the SQL task in the IP21 manager. To do this Select the TSL_SQL_Server task from Defined Task then double click on the command line parameter and type -n. Then restart the task
