Information on systems using WT30 FA Wireless SS Terminals (also referred
to as WT30 or WT30 Terminals in this manual) is provided here.
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 RS-
232C 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.
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 Sta-
tion as the Relay Station.
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 sim-
ply 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 termi-
nal 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.
Communications will continue via the Relay Station even if communications
with the Serial Master Station and I/O Slave Station are unstable, or if the I/O
Slave Station is removed.
Three antenna types are available: Magnet-base Antennas, Flat Antennas,
and Pencil Antennas.
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 communica-
tions programs for the WT30, reduces the load on system startup and mainte-
nance, 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).
