To change specific bits of output data, use a mask pattern. Data bits corresponding
to 1s in the mask pattern will change, but those corresponding to 0s will not.
Example:
Output data P = $0640 0 0 0 0 0 1 1 0 0 1 0 0 0 0 0 0
Mask pattern M = $0750 0 0 0 0 0 1 1 1 0 1 0 1 0 0 0 0
↓
Output relay before execution $3B36 0 0 1 1 1 0 1 1 0 0 1 1 0 1 1 0
Output result $3E66 0 0 1 1 1 1 1 0 0 1 1 0 0 1 1 0
(3) Accessing mode registers
- Reading from mode registers
To read from mode registers, use the STATUS statement.
STATUS SL, n ; I
SL : Slot number
n : Data position number
I : Integer-type variable or integer-type array variable for storing read
data
- Writing to mode registers
To write to mode registers, use the CONTROL statement.
CONTROL SL, n; I
SL : Slot number
n : Data position number
I : Constant, or integer-type variable or integer-type array variable storing
data to be written.
(4) Accessing output data registers
- Writing to output data registers
To write to output data registers, use the OUTPUT statement.
OUTPUT SL, n, NOFORMAT; I
SL: Slot number
n : Data position number
I : Constant, or integer-type variable or integer-type array variable storing
data to be written.
