PLC photoelectric sensor BCL 34 Description
Time Light barrier from 0
Ö
1
The light barrier is interrupted. The state is
present at the switching input of the BCL 34 and
does not activate the scanner
M 13 Bit 0.0 from 0
Ö
1
The BCL 34 signals to the controller, that the
light barrier has been triggered.
M 18 Bit 0.0 from 0
Ö
1
The controller activates the reading gate of the
BCL 34.
Light barrier from 1
Ö
0
At the switching input of the BCL 34, the light
barrier signals that the light beam is no longer
interrupted.
M 13 Bit 0.0 from 1
Ö
0
The BCL 34 signals to the controller that the
light barrier has been deactivated.
M 18 Bit 0.0 from 1
Ö
0
The controller closes the reading gate of the
BCL 34.
M 23 Bit 0.1 from 0
Ö
1
M 23 Bit 0.2 = 0 or
Bit 0.2 from 0
Ö
1
M 23 byte 1 = data length
M 23 byte 2 to 11 = result
After the reading gate has been closed, the
module decoding state signals the result to the
PLC:
Reading concluded bit 0.1 = 1 and barcode
decoded bit 0.2 = 0 (barcode decoded) or 1
(barcode not decoded).
The data length is entered into byte 1 (10 deci-
mal if reading has been successful, 1 if barcode
could not be recognised)
The decoding result is transmitted in the follow-
ing 10 bytes.
