Figure 4-10 Select Output Screen

Selecting an output with the Right-arrow or Enter key will present the screen
which permits definition of the output, as shown below.

The Left-arrow, Right-arrow, Up-arrow and Down-arrow keys provide access to
the Output Name, card#, pin# and Condition string edit fields. A 16-digit name
can be assigned to the logical input. Any entry other than 1 or 2 will be ignored
for the card#, as will a pin# less than 2 or greater than 9.

Figure 4-11 Program Output Screen

The output condition string is a logical statement that determines the state of the
output. The output relay is closed when the condition string is evaluated as true.
Otherwise, the relay is open. Each output condition string is evaluated ten times
per second (every 100 milliseconds).

4.3.3.3.1 ENTERING A CONDITION STRING

A condition string comprises one or more individual conditions linked together by
the logical operators ! NOT, & AND, | OR and parentheses ( ). Conditions are
chosen from a list. To enter a condition string correctly you must follow these
rules:

There must be an equal number of closed and open parentheses.

All conditions must be separated by either the & or the | operator.

Condition strings cannot end in an operator.

To enter a condition string, first highlight the condition string field. The second
line from the bottom of the screen displays the valid operators and parentheses.
