The Event Expression is a logical equation built to combine the condition/status of multiple events into a single
action. Other events will be referenced by their Event Name. These operands will evaluate those event's
condition/status to be a 0 (false/inactive) or 1 (true/active).
There are 4 logical test operations that can be performed on the operands: Once the desired information has
been selected, click on the NEXT button and the next dialog window appears:
NOT:
Represented by the exclamation symbol (!)
AND:
Represented by the ampersand symbol (&)
OR:
Represented by the pipe symbol (|)
EQU:
Represented by the equals symbol (=)
Examples:
EVT1 & EVT2 | EVT3 & !EVT4
!EVT1 & !( EVT2 || ( EVT3 & EVT4) ) | EVT5
$TAG1$ & $TAG2$ | $TAG3$ & !$TAG4$
!$TAG1$ & !( $TAG2$ || ( $TAG3$ & $TAG4$) ) | $TAG5$
EVT1 & MyEvent | $TAGNAME$
$TAG1$ & $TAG2$ | $TAG3$ & !$TAG4$
where EVT1, EVT2, EVT3, EVT4, EVT5 and MyEvent represents the event name and $TAG1$, $TAG2$,
$TAG3$, $TAG4$, $TAG5$ and $TAGNAME$ represents the I/O type register address.
Rules:
•
"!" only takes effect for the operand or the total result of the pair of parenthesis at its right hand side
•
“=” shall be between only two operands. Another “=” following is not allowed
•
EVT1 == EVT2 == EVT3, shall be written as EVT1 = EVT2 & (EVT2 = EVT3)
•
Operations are evaluated from left to right, unless parenthesis takes higher priority
•
Maximum level of cascaded parenthesis is 3
•
Maximum named event operands is 16
•
“!=” is not allowed. Instead, use EVT1 = !EVT2 or !EVT1 = EVT2
Click on the

button.
