Introduction
;*********************** Initialize and Set Variables **********************
UNITS = 1
;Define units for program, 1=revolution of motor shaft
ACCEL = 5 ;Set acceleration rate for motion command
DECEL = 5 ;Set deceleration rate for motion command
MAXV = 10 ;Maximum velocity for motion commands
V1 = 25 ;Set Variable V1 equal to 25
V2 = 75 ;Set Variable V2 equal to 75
DEFINE Output_On 1 ;Define Name for output On
DEFINE Output_Off 0 ;Define Name for output Off
;*********************** EVENTS *******************************************
EVENT SPRAY_GUNS_ON APOS > V1 ;Event will trigger as position passes 25 in pos dir.
OUT3= Output_On
;Turn on the spray guns (out 3 on)
ENDEVENT ;End event
EVENT SPRAY_GUNS_OFF APOS > V2 ;Event will trigger as position passes 75 in pos dir.
OUT3= Output_Off
;Turn off the spray guns (out 3 off)
ENDEVENT ;End even
;*********************** Main Program *************************************
PROGRAM_START:
;Place holder for main program loop
ENABLE ;Enable output from drive to motor
EVENT SPRAY_GUNS_ON ON ;Enable the ‘spray guns on’ event
EVENT SPRAY_GUNS_OFF ON ;Enable the ‘spray guns off’ event
WAIT UNTIL IN_A4==1 ;Ensure Arm is retracted before running the program
MOVEP 0 ;Move to position 0 to pick part
OUT1 = Output_On ;Turn on output 1 to extend Pick arm
WAIT UNTIL IN_A1==1 ;Check input to make sure Arm is extended
OUT2 = Output_On ;Turn on output 2 to Engage gripper
WAIT TIME 1000 ;Delay 1 sec to Pick part
OUT1 = Output_Off ;Turn off output 1 to Retract Pick arm
WAIT UNTIL IN_A4==1 ;Check input to make sure Arm is retracted
MOVED 100 ;Move to Place position
OUT1 = Output_On ;Turn on output 1 to extend Pick arm
WAIT UNTIL IN_A1==1 ;Check input to make sure Arm is extended
OUT2 = Output_Off ;Turn off output 2 to Disengage gripper
WAIT TIME 1000 ;Delay 1 sec to Place part
OUT1 = Output_Off ;Retract Pick arm
WAIT UNTIL IN_A4==1 ;Check input to make sure Arm is retracted
GOTO PROGRAM_START ;Loop back and continuously execute main program loop
END
1.9 IF/ELSE Statements
An IF/ELSE statement allows the user to execute one or more statements conditionally. The programmer can use an
IF or IF/ELSE construct:
Single IF example:
This example increments a counter, Variable “V1”, until the Variable, “V1”, is greater than 10.
Again:
V1=V1+1
IF V1>10
V1=0
ENDIF
GOTO Again
