CRIMSON USER MANUAL - MODULAR CONTROLLER
The sample shown below sets several variables, and then changes the display page…
Motor1 := 0;
Motor2 := 1;
Motor3 := 0;
GotoPage(Page1);
The actions will be executed in order, and the program will then return to the caller.
IF STATEMENTS
This type of statement is used within a program to make a decision. The construct consists of
an if statement with a condition in parentheses, followed by an action (or actions) to be
executed if the condition is true. If more than one action is specified, each should be placed
on a separate line, and curly-brackets should be used to group the statements together. An
optional else clause can be used to provide for code to be run if the condition is false.
The architecture of the if statement is as follow…
if( condition ){
action1;
}
else{
action2;
}
The example below shows an if statement with a single action…
if( TankFull )
StartPump := 1;
The example below shows an if statement with two actions…
if( TankEmpty ) {
StartPump := 0;
OpenValue := 1;
}
The example below shows an if statement with an else clause…
if( MotorHot )
StartFan := 1;
else
StartFan := 0;
Note that it is very important to remember to place the curly-brackets around groups of
actions to be executed in the if or else portion of the statement. If you omit the brackets,
