 Condition Aggregate Tags
For each OPC item you connect you, you can specify a condition - from that setup, the OPC Time Monitor
calculates a number of items for when the item is In Condition, Out Of Condition, and Stable.
The first items exposed are a set of aggregates for the selected condition - in this example "$InCondition" is chosen

 Time Format Items - these items are available for any OPC item provided by the OPC Time Monitor in VT_DATE Format.
For each item, the time in the condition is available in different time formats based on the client needs - i.e. in
days, hours, seconds, minutes, etc.
In the listings below "TimeBranch" refers to the particular summary value - for example, ServerTime is a
"TimeBranch", meaning you could access ServerTime in seconds by using the item name YourItem!$InCondition!ServerTime!Seconds
