Um, not sure if you are missing something, or I am!
The only time the strategy tags are connected to pac display is in configurator mode.
Once you have the IP address and tags connected to the graphics, you can (but dont!) toss out the strategy.
When pac display runtime starts, it just starts scanning the tags at the IP address you set up in config mode.
In other words, the computer that is running pac display runtime, it does not even need the strategy file or pac control installed on it.
If you have the wrong IP address configured, when runtime starts, all the graphics will be red (or what ever color you set them up to be) and there will be no data.
There is no hazard.
You dont get the option to pick the strategy file with runtime. Runtime does not need the strategy file.
You must connect the right tags to the right controller (IP address) in config mode. Once that is done. You are done for runtime.
Hope that helps.
