The Compare block can make a numerical comparison. Flow follows one of the two exit 

paths of the Compare block based on the result of the comparison. The type of comparisons 

available are less than (<), equal to (=), greater than (>), greater than or equal to (>=), less 

than or equal to (<=), and IsEven. There are also special direct time and date comparison 

operations for date, time, day of week, day of month, and day of year.

Double-click the Compare block to edit its expression. This displays the “Compare Block... 

Configuration” tab (see Figure 4-4). This example compares the register “R-01” with the 

name “Big Number Register” and register “R-07” that has the default name.

Both Registers and Timer/Counters have subtypes. The default subtype of both is 

“Unconfigured”. If selecting an unconfigured type for the first operand, nanoNavigator 

prompts for selection of its type. The subtype of the second operand must match the 

To compare Boolean values, use the Decision Block (see “Decision Block” on page 4-11).

When using a constant in the Compare Expression, the variable operand must be the First 

Item and the constant must be Second Item.
