Description
Time
Photoelectric sensor from 0 ->
1
The photoelectric sensor is interrupted. The signal of the switch
-
ing output of the photoelectric sensor is present at the switching
input of the device and activates the scanner.
Photoelectric sensor from 1 ->
0
The beam of the photoelectric sensor is cleared before a read
result is present. The photoelectric sensor sets the switching
input of the device to 0 and deactivates the scanner.
M 23 bit 0.1 from 0 -> 1
M 23 bit 0.2 from 0 -> 1
M 23 byte 1 = 1
M 23 byte 2 = result
The module decoding state signals:
Reading concluded bit 0.1 = 1 and bar code not decoded bit 0.2
= 1.
The data length is entered in byte 1.
The result hex 3F (? = no read) is transmitted.
