If the Driver module canít find the stPublicListOfStrategyTags table in the strategy, it automatically retrieves the strategyís inventory of all driver-supported tags in their native format. This means that PAC Control's object inventory will not match Ignitionís object inventory. (For example, a 32-bit integer in PAC Control may be used as a number, a bitmask, and a zero/non-zero Boolean value.) For performance reasons, we strongly discourage scanning all tags.
