Basic operation 11-7
1.5 DI/DO (digital input and output) operation
■
Overview
The following example shows input/ output signal operations through the general-purpose input/
output device.
Processing flow
Wait until DI2( ) is all at "0".
Set all of DO2 ( ) to "1".
Wait 1 second.
Wait until DI2 (0) is at "1".
END
N
DI2 (1)="1"?
N
＝
1
N ＞ 20
Set all of DO2 ( ) to “0”.
Wait 0.5 seconds
N=N+1
Set DO2 (7, 6, 1, 0) to "1".
Wait 2 seconds
Set all of DO2 ( ) to "0".

START
Wait until DI20 to DI27 become "0".
DO20 to DO27 become "1".
Wait until DI20 becomes "1".
• DO processing ends if DI2(1) is "1".
• Repeated until N=20 if DI2(1) is "0".
"1" is assigned to "N".

SAMPLE
WAIT DI2()=0 ···················· Waits until DI20 to DI27 become "0".
DO2()=&B11111111 ················ DO20 to DO27 become "1".
DELAY 1000
WAIT DI2(0)=1 ··················· Waits until DI20 becomes "1".
N=1
*LOOP1:
IF DI2(1)=1 THEN *PROGEND ······· Jumps to *PROGEND if DI21 = 1.
IF N>20 THEN *ALLEND ············ Ended in N > 20 (jumps to *ALLEND).
DO2()=0
····················· DO20 to DO27 become "0".
DELAY 500
N=N+1
GOTO *LOOP1 ····················· Loop is repeated.
’END ROUTINE
*PROGEND: End processing.
DO2(7,6,1,0)=&B1111 ············· Sets DO27, 26, 21, 20 to "1".
DELAY 2000 ····················· Waits 2 seconds
DO2()=0
····················· Sets DO20 to "0".
