While developing my current project at the office, I defined a UDT that had various tags with Tag History defined. using the same History Provider definition as the database name at the client’s site. However when I fired up the screen with the easy chart on it at the customer it was red indicating an error.
I’m thinking that I need to do something to make sure that their historical database has the correct definitions.
Should I go through the UDT definition and turn off the history for each tag, then turn it back on? I’m still modifying things in more than one location. Sometimes I’m working in the office on my local setup, and sometimes I’m at the customer. In each case I am exporting the project and the tags and importing them into the older site to keep both sides in sync. Will this cause problems for the historian?
On another note, can the charting show a combination of live and historical data? If so can you point me to where the method do configure that properly is defined please?
