Caution during Use
© Copyright Reserved Autonics Co., Ltd. vii
Caution during Use
Follow instructions in ‘Caution during Use’. Otherwise, it may cause unexpected accidents.
ABUS power and I/O power should be insulated by the individually insulated power device.
Power supply should be insulated and limited voltage/current or Class 2, SELV power
supply device.
Use the rated standard cables and connectors. Do not apply excessive power when
connecting or disconnecting the connectors of the product.
Keep away from high voltage lines or power lines to prevent inductive noise.
In case installing power line and input signal line closely, use line filter or varistor at power
line and shielded wire at input signal line.
For the stable operation, use shield wire and ferrite core, when wiring communication wire,
power wire, or signal wire.
Do not use near the equipment which generates strong magnetic force or high frequency
noise.
Do not touch the module communication connecter part of the base.
Do not connect or remove the base while connected to a power source.
For removing the terminal, body or base, do not operate units for a long time without it.
This unit may be used in the following environments.
①Indoors
②Altitude max. 2,000m
③Pollution degree 2
④Installation category II

DAQMaster, a device integration management program, provides the expanded user
convenience. You can use the module setting, real-time control, and monitoring/diagnosis
function of input/output signal (except ARIO-C-PN and ARIO-C-PB). Also, you can arrange
products through virtual mode and recommended sorting.

2 Protocol overview

2Protocol overview
2.1 Modbus TCP
The Modbus protocol is the typical means of transfer with TCP / IP and commonly used to
connect industrial electronics. Simple and robust, it has become the de facto standard
communication protocol and is currently used to connect industrial electronics.
ARIO-C-MT, Modbus TCP-Based Coupler, synchronizes the data of all connected I / O modules
with Modbus TCP. The coupler determines the physical structure of the node and automatically
creates a local process image of all the I / O. It also includes a mixed arrangement of analog
(word) and digital (byte) modules.
The process image consists of the input and output data area.
2.2 Basic memory map of field network
The memory map is based on the addressing system of Autonics.

4.3 Rotary switch for communication setting
4.3.1 Transfer rate
Based on the network quality, Auto-Negotiation is performed to determine 10 / 100Mbps.
4.3.2 Switch for station no.
Switch
Description
Station no.: X16
Use to distinguish the order (name) of couplers.
Range: 01 to 255
Station no.: X1
The rotary switch cannot be changed while the power is operating. To apply the changed rotary
switch, the coupler must be turned on again.
The switch for station number can change the last 3 of the IP address '192.168.2.3' that the
coupler saves. You can also change the IP address arbitrarily via DAQMaster.
[Example] ‘12h' of the switch means '192.168.2.18'.
However, if settings of switches are all '00', the station number (IP address) is set based on the
information that the coupler saves.
