The remaining columns are the Node, Type and Tag of the input. It is highly recommended
that Tags be assigned to all zones and devices intended for use in Advanced Logic for clarity
sake.
The circuit, timer or switch can be simply tested for TRUE and FALSE, or a particular Device
Status can be tested. If a status is selected in the Device Status drop down, it will be
appended in the form of :x to the device ID when it is inserted into the equation. Each one
applies a different mask to the device's state.
Right hand pane
The right hand pane shows the current equation, if any, on entry or the equation under
construction.
Although the user can type into the right hand pane, it is recommended that they insert
operands and operators using the controls.
To enter an input, double click it in the left hand list or select it and press the insert button
>. The ID of the input will be inserted in the equation at the current cursor location.
To enter an operator, click one of the operator buttons, over top of the Equation window.
To enter multiple inputs separated by commas, select them in the list by using the mouse in
combination with the Ctrl key or Shift key. Press the insert button. If an operation is to be
applied on the inputs, such as Ckt1 OR Ckt2 OR �, select the inputs from the list and then
press the operator button. The complete expression, enclosed with parentheses, will be
inserted into the equation.
EQU
The EQU operand is used in combination with a System Define (a constant) and Device
Status. It tests a device's state and produces a TRUE|FALSE result. You may have to apply a
device mask to isolate the states you want to test.
e.g. **-**-**-TM-016 EQU TIMER_RUNNING Test for a timer running.
e.g. 01-00-02-IN-003:L EQU ALARM_LEVEL2 Test an input's alarm level
Note: not all Sys Defs can be applied to all circuit types. The user is responsible for choosing
a valid combination of device mask and Sys Def.
As per UL 864 and UL 2572 only usage of an input's immediate TRUE|FALSE value (without the
application of a mask and a test for equality) is permissible. That is, no combination of Device
Status, the operator EQU or Sys Def should be used.
