I am having trouble adding/removing variables from the Process Data Manager. 3 out out 5 times when I click on 'Update Items', the system stucks while 'Generating items' and I have to shut web IQ and restart the core to restore the connection. This started to happen after I created a Recorder and Trend variables, although it is still happening even after I deleted them, so not sure if they are what causing the problem.
Any ideas why would this happen and how to solve it?
Found the issue, some variables were removed/altered from the PLC but their corresponding tags still existed on WebIQ, and understandably it did not like this when updating items. I had to delete all the variables and reload them again from the browser tab.
So I now understand that we have to manually maintain the PLC variable list to match the WebIQ taglist.
