The IO Mask and IO Value fields need to be entered. The IO Mask field determines
which bits in the trigger word are the state of the conditional trigger. If one of the check
boxes is not checked, this represents a “don’t care” condition. For example, if Binary
Input Word 1 is selected, and the IO Mask is equal to 3, the program would only look at
the first two bits of Binary Word 1 and the other fourteen bits would be don’t cares. If a
register input/output is being used, and the collection should trigger when the register
reaches a certain value, the IO Mask should be –1.
In the case of binary inputs/outputs, the IO Value specifies the state of the bits that trigger
the data acquisition. For example, if Binary Word 1 is selected and the IO Value is equal
to 1, bit 1 must be a one and all other bits that are in the IO Mask must be zero to trigger
data collection. For register inputs/outputs, the IO Value is the value of the register that
will trigger data collection.
