Do value formats affect alarm condition evaluations?

Yes, the format set for a value in TopView sets both the value used for display and the value used for comparison against the alarm conditions set for the row. For example: a TopView row monitoring a float tag has a format for a whole number (i.e. "0"), if the row's value is "120.056", TopView will use the value "120" for comparison against the row's alarm conditions. Row formats are also be applied to any tags used as limit condition values.
