Function block status values

The following table lists all the function block status values.

Status propogation is determined by first checking the quality (Bad=0, Uncertain=1, GoodProcess=2, and GoodCascade=3). If one status has a lower value than the other, then it is determined to be worse. If the quality value is the same, then the quality substatuses of the two are compared, and the higher substatus is determined to be worse. If the quality substatus is the same for both, then the limit fields of the status are checked with the higher limit being determined as worse.

Therefore, to determine the worst status between multiple values, find the values you see is in the table and determine which value is worse by the placement in the table.
