Communication
Protocol
Parallel I/O Data is exchanged between an
external device and the code
reader through combinations of
ON/OFF signals from multiple
physical contacts.
EtherNet/IP This is an open communica-
tions protocol. Tag Data Links
are used for communication
with the code reader. On the
PLC, structured variables are
created that correspond to the
control signals, Command/
Response data, and Read data.
These variables are then used
as I/O Tag Data Links to ex-
change data between the PLC
and the code reader.
PROFINET This is an open communica-
tions protocol. Software-based
RT (Real-time) communica-
tions, (SRT) is used for commu-
nication with the code reader.
The control signals, Command
Area/Response Area, and area
to store Read result data are
assigned in the I/O memory of
the PLC, and data is ex-
changed cyclically between the
PLC and the code reader.
Command frames are sent to
the code reader and Response
frames are received from the
code reader without the use of
any specific protocol.
Data can be exchanged be-
tween the PLC, computer, or
other external device and the
code reader in ASCII or binary
format.
Serial (RS-232C) Data can be exchanged in AS-
CII format over the RS-232C
cable connection between the
code reader and its controlling
device (PLC, PC, or other ex-
ternal device).
