Parallel Output Variable - Omron SCARA YRCX Series Programming Manual

Parallel output variable

Specifies the parallel output signal or indicates the output status.
Format 1
DOm(b,···,b)
Format 2
DO(mb,···,mb)
Values m : port number .................... 0 to 7, 10 to 17, 20 to 27
b : bit definition .................... 0 to 7
If the bit definition is omitted in Format 1, bits 0 to 7 are all selected.
Examples: A%=DO2()
• When specifying multiple bits, specify them from left to right in descending order (high to low).
MEMO
• If an output port does not actually exist, the data is not output externally.
→Output status of DO(27) to DO(20) is
assigned to variable A%.
A%=DO5(7,4,0)
→Output status of DO(57), DO(54) and
DO(50) is assigned to variable A%.
(If all above signals are 1(ON), then A%=7.)
A%=DO(37,25,20)
→Output status of DO(37), DO(25) and
DO(20) is assigned to variable A%.
(If all above signals except DO(20) are 1
(ON), then A%=6.)
DO3( )=B%
→Changes to a status in which the DO(37)
to DO(30) output can be indicated by B%.
For example, if B% is "123": If a binary
number is used, "123" will become
"01111011", DO(37) and DO(32) will become
"0", and the other bits will become "1".
DO4(5,4,0)=&B101
→DO(45) and DO(40) become "1", and DO(44) becomes "0".
