Precautions

WARNING

Always provide protective circuits in the network. Without protective
circuits, malfunctions may possibly result in accidents that cause serious
injury or significant property damage. Provide double or triple safety
measures in external control circuits, such as emergency stop circuits,
interlock circuits, or limit circuits, to ensure safety in the system if an
abnormality occurs due to malfunction of the product or another external
factor affecting the product's operation.

Design the system to ensure safety in the event of temporary
interruptions in communications due to interference with the
electromagnetic waves used for communications caused by the ambient
environment and application methods.

Do not use this product for real-time control.

Using the FA Wireless SS Terminal near a pacemaker or other medical
device may affect the operation of the medical device, possibly resulting
in serious injury. Never use the FA Wireless SS Terminal near
pacemakers or other medical devices.

CAUTION

Make sure that the direction and polarity (+/−) are correct when
connecting terminal blocks and connectors. Turning ON the power to I/O
circuits with the I/O cables connected in reverse, may result in a blown
output fuse.

Do not apply a voltage or connect a load to the outputs that exceeds the
maximum switching capacity.

Leave the dustproof label attached to the Unit when wiring. Be sure to
remove the label after the completion of wiring, however, to ensure
proper heat dissipation. Removing the label during wiring or leaving the
label attached after wiring may result in fire.

Do not allow pieces of metal, wire clippings, or fine metallic shavings or
filings from installation to enter the product. Doing so may occasionally
result in minor electric shock, fire, or malfunctions.

Do not attempt to disassemble, repair, or modify the product, or touch
the internal parts of the product. Doing so may occasionally result in
minor electric shock, fire, or malfunctions. In Japan, disassembly and
modification is also prohibited under Japan's Radio Law and may be
punishable by law.

1-1 Features

Information on systems using WT30 FA Wireless SS Terminals (also referred
to as WT30 or WT30 Terminals in this manual) is provided here.

1-1-1 Overview

The WT30 System consists of a Serial Master Station and I/O Slave Stations.
The Serial Master Station is a wireless terminal that collects ON/OFF data
using wireless communications and is connected to a device with an RS­232C interface (e.g., a personal computer or PLC). I/O Slave Stations with I/O
terminals can also be connected to a DeviceNet-compatible WD30 Master.

Simple Relay Functions The relay functions enable an increase in the communications area. The

WT30 system supports a maximum of one relay stage using an I/O Slave Sta­tion as the Relay Station.

Antennas (Optional) Three antenna types are available: Magnet-base Antennas, Flat Antennas,

Changing frequencies removes interference between different sets installed in
the same area. This enables you to construct a wireless system consisting of
up to 10 sets (depending on the installation environment).

Supporting up to 67 channels, you can construct multiple systems without
interference caused by intermodulation.

DIN Rail mounting makes installation easy. The system can be registered sim­ply by setting the switches on the WT30 Terminal, so Support Software is not
required.

I/O Slave Stations are available in three types: With 16 inputs (DC inputs), 8
inputs/8 outputs (DC inputs/transistor outputs), or with different output termi­nal polarity.

Registering the I/O Slave Station data (serial number and I/O size) in the
Serial Master Station enables communications to be performed with specified
I/O Slave Stations only.

The LED display on the WT30 Terminal can be used to check the WT30's
error status, whether wireless communications are normal, and the received
signal strength.

and Pencil Antennas.

Interface

Supported in OMRON
Function Block Library for
SYSMAC CS/CJ-series
PLCs

2

A CompoWay/F command must be created to read (write) ON/OFF or other
data. By using the OMRON Function Block Library, PLC users can reduce the
amount of programming required.

The WT30 is supported the OMRON Function Block Library for SYSMAC CS/
CJ-series Programmable Controllers. The I/O Slave Station's input conditions,
output controls, and wireless communications status can be read simply via
the WT30-M01-FLK Serial Master Station connected to the PLC. Using the
OMRON Function Block Library eliminates the need to create communica­tions programs for the WT30, reduces the load on system startup and mainte­nance, and improves software quality through programming standardization.
For details on the OMRON Function Block Library, refer to the OMRON FB
Library Start-Up Guide (Cat. No. R123).

Fe at ur e s Section 1-1

1-1-2 System Configuration

The Serial Master Station is connected to the PLC (Programmable Controller)
or personal computer to perform ON/OFF data communications with the I/O
Slave Stations. The I/O Slave Station can also be used as a Relay Station to
select the path and extend the communications area.

Connecting Multiple Serial
Master Stations

The K3SC RS-232C/RS-485 Interface Converter can be used to configure a
network requiring two or more Serial Master Stations (31 stations max.) or in
environments in which communications are not possible even when Relay
Stations are used in the system. Make sure that the Serial Master Stations are
each allocated unique unit numbers and frequency channels. For details on
wiring cables, refer to the operation manual provided with the K3SC Interface
Converter.
