CKt No. – The numerical value assigned to each status, switch, timer, interval, zone or input
by the Flex-Net Configurator
A double asterisk "**" is used if there is no applicable value for certain ID components such as
a Loop No. for a system status.
The Node and CPU columns list the numerical value of the node pertaining to each input
device or zone. A default value of 255 is applied to system statuses, control switches, timers,
and intervals as they are global inputs which apply to the entire network.
The Ckt No column consists of numerical values assigned by the Flex-Net Configurator to
each input.
The Ckt Type column identifies the type of input. Inputs can vary from system statuses,
switches, intervals, timers, input devices, and input zones.
The Tag column includes a general description of each input that helps identify it. This aids in
constructing an equation.

7.1.3 Equation Dialog Box

The Equation Dialog Box is where the logic equations are structured. To insert an input, select
the input from the Eligible Input List and click the > button above the list.
To insert an operand, select the appropriate button above the Equation Dialog Box. To insert a
System Define, use the drop down to select the appropriate system define and then click the
Sys Def button. The Undo button removes the last change to the equation. The Redo button
reapplies the last removed change to the equation.

7.1.4 Comment Box

The comment box is used to attach comments to the advanced logic equation. Comments are
important for quickly explaining the intended function of an equation. This will allow for easier
troubleshooting and quicker review of the configuration later on.

Advanced Logic Example

7.2.1 Objective

To create an advanced logic equation using a combination of operators. The advanced logic
equation will be part of a virtual input zone. It will reference inputs that exist in a separate
group from the equation's virtual input zone. This virtual input zone will be referenced by an
output in its group that will activate when the equation that drives the zone becomes true.

7.2.2 Procedure

1. Create an alarm input zone in the same group as the outputs that are to be activated.
Tag the zone "Virtual Alarm Zone 1".
2. Create three input devices and tag them appropriately.
3. Select the alarm input zone and then select the Advanced Logic tab. Click the Edit
button and the Advanced Logic Dialog Box appears.
4. Select the Device Status mask ":A" for alarm.
