There are 48 identical digital elements available, numbered 1 to 48. A digital element can monitor any FlexLogic operand
5
and present a target message and/or enable events recording depending on the output operand state. The digital element
settings include a name to be referenced in any target message, a blocking input from any selected FlexLogic operand,
and a timer for pickup and reset delays for the output operand.
