Applicable Communications Protocols for the V430-F Series
The V430-F Series can be controlled from a PLC, computer, or other external device using various
communication protocols.
The following types of communication protocols can be used for controlling the V430-F series from an
external device.
Code
Reader
PLC
Computer
Control can be performed through different communications protocols.
Serial (RS-232C)

and the code reader through combinations of
ON/OFF signals from multiple physical con-
tacts.

EtherNet/
I
P
This is an open communications protocol. Tag
Data Links are used for communication with
the code reader. On the PLC, structured varia-
bles 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 exchange data between the PLC
and the code reader.

PROFI-
NET
This is an open communications protocol. Soft-
ware-based RT (Real-time) communications,
(SRT) is used for communication 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 exchanged cyclically between
the PLC and the code reader.

Frame
transmis-
sion
Serial
(TCP)
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 between the PLC,
computer, or other external device and the
code reader in ASCII or binary format.

Serial
(RS-232C
)
Data can be exchanged in ASCII format over
the RS-232C cable connection between the
code reader and its controlling device (PLC,
PC, or other external device).
