Digital Output Function
Output bit
Individual digital output points are called output bits.
When the number of output points of a device is 4, the bits are determined as bit 0 - bit 3.
Output in Bits
The state of each output bit can be changed to ON or OFF by specifying the bit and setting it to 1 or 0.
Output in Bytes
Individual output bits can be output in byte units.
When the number of output points of the device is 4, the individual output bits are arranged as shown
below and byte data to be output is a value between 0 and 15.
Ex. Output of bit3 (ON), bit 2 (OFF), bit 1 (ON) and bit 0 (OFF)
Byte data = 10 (AH)
Bit 0 Bit 3 Bit 2 Bit 1
1(ON) 0(OFF) 1(ON)
Bit 0 Bit 3 Bit 2 Bit 1
0(OFF)
