FAQs

Below are many of our frequently asked questions. Please contact techsupport@activelogix.com if you need additional assistance related to your Periscope installation. 

1. Q. I have tagged my site(s) and data and created the necessary references / relations in Niagara. What do I do next? 
   A. You should now select which "sites" you want defined in Periscope. Navigate to Periscope's settings page and click "Choose Sites" to make sure you have at least one site selected. 
   
   
2. Q. I just updated my Periscope JAR/module, why won't my dashboard load now?
   A. You must re-fetch your license after a JAR/module update. Navigate here for instructions on fetching your license. 
   
   
3. Q. Why are my histories not showing up in query or select mode?
   A. All records that have a history must have their corresponding point tagged with "hs:his" and "n:history", with the n:history string path pointing to the trend record location on the station (for Niagara Periscope installations). Check that your history or histories have these tags and refresh the haystack cache if needed to pull these tags into Periscope. 
   
   
4. Q. Why is my PX View not displaying properly (the graphic is cropped)? 
   A. PX Views will sometimes behave abnormally when a PX page is opened in a browser window in addition to Periscope. The solution is to close any other tabs or windows that are viewing the PX page and refresh the Periscope dashboard. 
   
   
5. Q. As an administrator, how do I add user restrictions?
   A. Periscope can prevent users from making any modifications, and/or remove access to the Periscope settings view. To begin, navigate to the Periscope user Directory:
   
   1. from station config, navigate to Services > PeriscopeService > Periscope Database > Users
   2. right-click on the particular user's folder and choose Edit Tags

   3. add or edit the following tags as follows:
      
      

      Tag name	Type	Value	Description
      hs:readOnly	Boolean	true	when readOnly is true, user is not able to make changes
      hs:showSettings	Boolean	false	when showSettings is false, user is not able to navigate to the settings page

   4. after change, load cache: Services > PeriscopeService > HaystackCache > Load Cache in Actions
