Example:
EVENT LimitSwitch IN_A1 RAISE ; limit switch event
Jump LimitSwitchHandler ; jump to process limit switch
ENDEVENT
V0=0
EVENT LimitSwitch ON
Again:
HALT
;system controlled by interface
LimitSwitchHandler:
EVENTS OFF
;turn off all events
ICONTROL OFF ;disable interface control
STOP MOTION QUICK ;
DISABLE ;optional DISABLE
V0=1 ;indicate fault condition to the interface
ICONTROL ON
EVENTS ON
GOTO AGAIN
IF If/Then/Else Statement
Purpose
The IF statement tests for a condition and then executes the specific action(s)
between IF and ENDIF statements if condition is satisfied. If condition is false, no
action is taken and the instruction following ENDIF statement is executed. Optionally,
a second action(s) may be specified to be executed if the condition is false.
Syntax
IF
{statements 1}
[
ELSE
{statements 2}

ENDIF
The condition to be tested. The condition may be a comparison, an input
being TRUE or FALSE (H or L) system flag or a variable used as flag (if 0 - false, else

Comparisons compare the values of two operands and determine if the condition is
TRUE or FALSE. A comparison may be greater (>), less than
(<), less than or equal (<=), or greater than or equal to (>=). The
