DI
Acquires the input status from the parallel port
Format
1. LET expression = DIm(b,···,b)
2. LET expression = DI(mb,···,mb)
Values
m: port number .....................
b: bit definition ......................
0 to 7, 10 to 17, 20 to 27
0 to 7 (If omitted, all 8 bits are processed.)
If multiple bits are specified, they are expressed from the
left in descending order (high to low).
Explanation
Indicates the parallel input signal status.
Enter "0" if no input port exists.
SAMPLE
A%=DI2()
····················· The input status from DI (27) to DI (20)
is assigned to variable A%.
A%=DI5(7,4,0) ·················· The DI (57), DI (54), DI (50) input
status is assigned to variable A% (when
all the above signals are "1" (ON), A% = 7).
A%=DI(37,25,20) ················· The DI (37), DI (25), DI (20) input
status is assigned to variable A% (when
all the above signals except DI (20)
are "1" (ON), A% = 6).
Reference
For details, refer to Chapter 3 "9.3 Parallel input variable".
