Configuration
Choosing these items (and clicking ADD ) produces the Boolean expression:
SD on CAM1 is switched to SD on MON2
In the preceding illustration, that expression is ANDed with another expression
INPUT 3 OR INPUT 8
The relay chosen (relay 1) will transition when the entire expression is true. That is, when the
switch occurs and either of the inputs (3 or 8) transitions from off to on.
(To allow a relay to switch when an input transitions from on to off, precede the input term by
“NOT.” For example, the expression
INPUT 3 OR NOT INPUT 8
will evaluate true either when input 3 goes from off to on or when input 8 goes from on to off.)
You can also include one or more expressions regarding the state of output ports. You must choose
a entry in the drop-down menu. These are the choices:
The operation was successful
Destination port locked
Destination port protected
Router offline / unavailable
No tieline available
Used as master point to point
Used as master without responses
Used as broadcast master
Used as slave point to point
Used as slave without responses
Used as Broadcast Slave
Choosing ‘Used as broadcast slave’, VTR3 , and CTRL for output port status produces the proposition
CTRL on VTR3 has status of ‘Used as broadcast slave.’
which you can combine with other expressions as you require.
Four arrow buttons at the lower left corner of the relay dialog allow you to traverse the expression
you are building:
The left double arrows highlights the first term or operator in the expression. The right double
arrow positions you at the very end of the expression where you may add more items.
The single arrows select and highlight the previous or next terms, operators, or spaces between
terms and operators. If you wish to change a term, you may highlight it, reconstruct the term in the
appropriate entry fields, and click the Change button to effect the change.
Using the arrows is the only way to position between two items or at the end of the expression. You
can double-click a term or an operator to select it directly.
You can click “Check Syntax” to evaluate the syntax of your complete expression. Generally, an
syntax error will have occurred because you forgot an operator between terms or you have an extra
operator at the end.
You can click “Delete” to delete a selected term or operator.
