Applicable Communications Protocols
The communication protocols of each communication method that can be used with the Sensor are as follows:
Communi- Communi- Overview
cations cations
method protocol
Contact Parallel Data is exchanged between an external device and the
inputs Sensor through combinations of ON/OFF signals from
multiple physical contacts.
Data shar- PLC Link This is OMRON's communications protocol for Vision
ing System.
The control signals, Command Area/Response Area,
and area to store measurement data are assigned in
the I/O memory of the PLC, and data is exchanged
cyclically to share data between the PLC and the Vision
System.
EtherNet/IP This is an open communications protocol.
Tag data links are used for communication with the Sen-
sor.
On the PLC, structure variables are created that corre-
spond to the control signals, command/response data,
and measurement data. These variables are then used
as tags to input and output data through tag data links
to exchange data between the PLC and the Sensor.
PROFINET This is an open communications protocol.
RT (Real-time) of soft real-time communication (SRT) is
used for communication with the Sensor.
The control signals, Command Area/Response Area,
and area to store measurement data are assigned in
the I/O memory of the PLC, and data is exchanged
cyclically to share data between the PLC and the Vision
System.
Frame No-proto- Command frames are sent to the Sensor and response
transmis- col (TCP) frames are received from the Sensor without the use of
sion No-proto- any specific protocol.
col (UDP) Data can be exchanged between the PLC, computer, or
other external device and the Sensor by sending and
receiving ASCII or binary format data.
No-proto- This is a command system (FINS) for message services
col (FINS/ that can be used in common on OMRON networks.
TCP) Data can be exchanged between an OMRON PLC and
the Sensor by a command/response method.
*1: When connected to a CJ-series PLC, specify the areas in the I/O memory.
*2: This connection is via the RS-232C Interface Sensor Data Unit. Only supported on the FQ2-S3/S4/CH series.
