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.
Install Multiple Sets in the
Same Area
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).
Advantage of Full Range
of Channels
Supporting up to 67 channels, you can construct multiple systems without
interference caused by intermodulation.
Easy Installation and
Settings
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 with
Built-in I/O
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.
High-level Security
Wireless Communications
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.
Determine Operating
Status from the LED
Display
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.
Path Switching Function
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.
Antennas (Optional)
Three antenna types are available: Magnet-base Antennas, Flat Antennas,
and Pencil Antennas.
Compatible with Generalpurpose RS-232C
Interface
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.
Supported in OMRON
Function Block Library for
SYSMAC CS/CJ-series
PLCs
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).
Section 1-1
Features
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.

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.

Determining the Antenna Installation Position
The WT30 uses radio waves with a frequency of 2.4 GHz, which is very high.
High-frequency waves exhibit strong rectilinear propagation and are reflected
easily. For this reason, careful consideration of the Antenna installation position is required to achieve optimum wireless performance.
1,2,3...
1. If possible, install Antennas so that there is a direct line of sight between
them.
High-frequency waves, which exhibit strong rectilinear propagation, are
used and so it is difficult for the waves to reach areas that are not in a direct
line of sight, as shown in the following diagram. This is a particularly important point for communications at long distances (e.g., exceeding 50 m or
60 m.)

Section 2-1
Installation
If the Antennas are installed in locations with relatively high ceilings and a
lot of open space, even if there is no direct line of sight between the Antennas, if one of the Antennas is installed in a high location, communications
may still be possible via radio waves that are reflected off the ceiling.
2. Install in as high a location as possible.
As mentioned in the preceding paragraph, if the Antennas are installed in
high locations, because the space surrounding the Antennas will be more
open, there will be less influence from obstacles, and the radio waves will
propagate more easily.

Obstacle
3. Do not place obstacles (especially metal objects) near the Antennas.
If there are obstacles near the Antennas (in particular, in the direction of
radio wave propagation), the radio waves may not be propagated due to
the influence of the objects. Metal objects have the greatest influence as
they reflect radio waves, whereas glass and plastic objects allow the waves
to pass through and so have the least influence. Be sure to install Antennas at least 30 cm away from any obstacles.
4. Cable Loss in Magnet-base Antennas
Loss occurs in the cable when using WT30-AT001 Magnet-base Antennas.
Therefore, the maximum communications distance is approximately 50 m
indoors, which is shorter than for Pencil Antennas.
5. Cable Bending Radius
The minimum bending radius for WT30-AT001 Magnet-base Antennas is
38 mm. Also, do not bend the cable at points less than 34 mm from the end
connected to the WT30 Terminal or at points less than 40 mm from the end
connected to the Antenna.
The minimum bending radius for WT30-AT002 Flat Diversity Antennas is
50 mm. Also, do not bend the cable at points less than 23 mm from the end
connected to the WT30 Terminal or at points less than 20 mm from the end
connected to the Antenna.

6. Separate different sets of Antennas as much as possible.
If different sets of Antennas are close to each other, they will influence
each other and thereby influence wireless communications, causing an increase in the number of retries, and a reduction in the possible communications distance. Separate different sets of Antennas by at least 2 m if
possible.
7. Do not install the two Magnet-base Antennas close to each other.
If the two Antennas are close to each other, the diversity effect will not be
utilized. Magnet-mounting allows the positions to be adjusted easily. If possible, separate the Antennas by an even greater distance.
8. Install the Antennas with the same orientation.
Install Antennas that are performing communications with the same orientation, as shown in the following diagram. Install Flat Diversity Antennas in
the same way. If they are installed at an angle of 90° to each other, the possible communications distance will be shortened.
9. Separate the Antennas from ID Tags by at least 3 m.
The OMRON V690 Microwave RFID System uses frequencies within the
range used by the WT30 Terminals. Therefore, if the two systems are used
on the same floor, observe the following points when installing the systems.
• Separate the Antennas and ID Tags by at least 3 m.
• Set the frequency to a channel other than channels 12 to 30 or channels 62 to 79.
10. Direction of Waves Emitted from Magnet-base Antennas
Antennas emit waves in certain directions, and there are certain directions
in which waves are received easily. These directions are known as the “directional characteristics.” The directional characteristics for Pencil Antennas and Magnet-base Antennas when they are installed vertically are
donut-shaped, spreading outwards horizontally. Radio waves are emitted
in every horizontal direction but are not emitted upwards or downwards.
Radio wave emissions from the tip of the Antenna are low, so the communications distance will be shortened if the tips of the Antennas for both the
WT30 Terminals are installed facing each other.

11. Other Points about Magnet-base Antennas
• The magnet on the Magnet-base Antenna is very strong. Do not remove the Antenna by pulling on the cover or cable. Doing so may damage the Antenna. Always hold the base when handling the Antenna.
• Twist the cable as little as possible.
• Design the hole for passing the cable through so that the cable is protected.
12. Direction of Waves Emitted from Flat Diversity Antennas
Flat Diversity Antennas also have directional characteristics, in the same
way as Magnet-base Antennas.

13. Do not subject the Antenna to shock.
Do not install the Antenna in a location in which it may be hit by other objects. If installation in such a location is required, take sufficient measures
to protect the Antenna. Subjecting the Antenna to strong shock may cause
either external or internal damage to the Antenna. Internal damage that is
not necessarily externally visible may prevent communications, such as
broken wires.

Flat Diversity Antennas
Secure the Flat Diversity Antenna to the Mounting Bracket with screws. The
Mounting Bracket includes a magnet for attachment to metal surfaces. Do not
tighten the vertical and horizontal angle adjustment knobs at first to allow
adjustment of the Antenna position and angle. After adjusting to the correct
position, tighten the knobs securely.

Using a DIN Rail
Do not install the WT30 in a metal panel when using a Pencil Antenna. Doing
so will decrease the wireless performance significantly. To install the WT30 in
a panel, use either a Magnet-base Antenna or Flat Antenna and install the
Antenna on the outside of the panel. Refer to Appendix D Optional Accessories on page 101.

Wireless System Design Considerations
Construction of Multiple Wireless Systems
When constructing a system for using multiple Serial Master Stations, the following points must be considered. Consult your OMRON representative.
Setting Wireless Channels
Frequencies that are not interfered with by radio waves must be selected for
the wireless channels. (Radio interference can be handled by retry processes
between the wireless networks, but will lengthen the system response time.)
The WT30 supports 67 wireless channels from which to select. As a rough
guide, however, a maximum of 10 wireless systems can be used in a single
area without radio interference on account of the following considerations.
1,2,3...
1. Do not select neighboring wireless channels as they have a large amount
of interference.
2. Due to the fundamental nature of radio waves, if two or more waves with
different frequencies are output at exactly the same time, mutual interference will occur between the different frequencies, and new waves will be
generated with frequencies at intervals equal to the intervals between the
output frequencies. (This phenomenon is called intermodulation.)
For example, if channels 5 and 9 are used, electromagnetic interference
will be generated with channels 1 and 13, as shown in the following diagram. In this case, channels 2 and 14 can be used, but the frequency of
channel 51 is located between the frequencies for channels 1 and 2, and
the frequency of channel 63 is located between the frequencies for channels 13 and 14. Therefore, the channel with the frequency following channel 1 is channel 51. Channels 5, 9, 51, and 63 can be used without
interference. For details on frequencies, refer to Appendix F Frequency Table on page 105.

Antenna Separation
Distance
The distance between WT30 Terminals has a large influence on the amount
of interference received. In particular, there may often be cases where Serial
Master Stations are installed relatively closely to each other. Separate the
Antennas for different Serial Master Stations by at least 2 m if possible.
Test Confirmation
Perform a test to see whether or not the WT30 Terminals are receiving interference. Use the RSSI (Received Signal Strength Indicator) on both the Serial
Master Station and I/O Slave Station to check the interference.
2-3-2
Communications Errors Caused by Intermodulation
Communications errors and retry processing may occur due to intermodulation resulting in transmission delays. To eliminate the influence of intermodulation, do not set the wireless channels for WT30 Terminals in every system to
frequencies at regular intervals.
2-3-3
Serial Master Station Input/Output Data
The Serial Master Station’s input/output data is cleared by turning OFF the
power. After turning ON the power, an output signal of all zeros (OFF) is sent
to the output of the I/O Slave Stations from the Serial Master Station.
(1) At power OFF:
All I/O data cleared.

Intermodulation
Due to the fundamental nature of radio waves, if two or more waves with different frequencies
are output at exactly the same time, mutual interference will occur between the different
frequencies, and new waves will be generated with frequencies at intervals equal to the intervals
between the output frequencies.

Scan List
Communications are divided into two types depending on whether the communications partner (I/O Slave Station) is registered or unregistered. Registration of communications partners is referred to as scan list registration. The
mode for communications with specified, registered communications partners
is referred to as scan list enabled mode. The mode for communications
between the Serial Master Station and unregistered I/O Slave Stations from
the specified node number 1 up to the specified number of nodes is referred
to as scan list disabled mode.
For details, refer to 3-6-1 Scan List Registration on page 50.

Mistaken recognition will occur if an I/O
Slave Station set with the same node
number or frequency channel is present
in the radio signal range.
Immediate operation is possible by simply
setting the frequency channel and node
number for the I/O Slave Station after it is
added or replaced. This usage is supported provided that the same frequency
channel is not already being used nearby,
and that the operation on a different frequency channel can be confirmed.
Communications are performed with registered I/O Slave Stations only. Therefore,
mistaken recognition will not occur. Communications are also only performed with
the specified I/O Slave Stations, thereby
eliminating unnecessary polling and
heightening security.
By registering the I/O Slave Station with
the serial number check enabled, re-registration at the Serial Master Station is
required when an I/O Slave Station is
replaced.
For details on using unregistered slave stations, refer to 3-4 Using Unregistered Communications Partners and for using registered slave stations, refer
to 3-5 Registering the Communications Partner.

Monitoring All Wireless Channels
The received signal strength for all wireless channels is automatically
scanned (the channel is changed every second), and the peak value is automatically recorded in EEPROM. (All channels are level 0 in the default settings.) The recorded peak value can be read during automatic scanning or
when automatic scanning is stopped. Approximately 70 seconds is required to
read the received signal strength for all channels. The automatic scan status
can be confirmed using the WS indicator. In the first cycle, the WS indicator
flashes green, and from the second and subsequent cycles, the WS indicator
is lit green.
When starting the automatic scan to perform monitoring for the first time,
allow a minimum of approximately 70 seconds before reading the peak values.
During automatic scanning, data is constantly overwritten. Therefore, to read
data collected onsite from an office, for example, the data must be read when
automatic scanning is stopped.
Note
1,2,3...
To change the installation position of the WT30 Terminal if the surrounding
radio wave conditions change, the recorded peak values for the received signal strength must be cleared to enable an accurate reading of the surrounding
radio wave conditions. Clear the recorded data and then start a new automatic scan.
1. Before turning ON the power, set the function setting switch as follows:
Bit 4: OFF (field strength monitor enabled)
Bit 5: ON (automatically select all channels)

Registering Communications Partners (All I/O Slave Stations)
Register I/O Slave Stations at the Serial Master Station. The Serial Master
Station performs wireless communications only with those I/O Slave Stations
that are registered. This prevents unwanted I/O Slave Stations from joining
the network. When registering, the serial number check can also be enabled
or disabled. Serial number recognition is the function that writes the I/O Slave
Station’s unique number to the Serial Master Station.
Scan List Registration
with Serial Number Check
Note
The serial number is registered at the same time as the corresponding I/O
Slave Station. This function has the advantage of preventing mistaken Slave
recognition even if a WT30 Terminal with the same channel (frequency), same
node number, and same model is in the radio signal range. The disadvantage
is that I/O Slave Stations that are replaced must be re-registered.
When the serial number check is not required, turn OFF bit 9 of the Serial
Master Station’s function setting switch (serial number check disabled).

2. Registering specified I/O Slave Stations
50
Section 3-6
Function Setting Switch
Select to either register all I/O Slave Stations automatically by specifying the
highest I/O Slave Station node number, or register specified I/O Slave Stations by specifying the I/O Slave Station node numbers individually. When registering all I/O Slave Stations at the same time, it is recommended to set the
I/O Slave Station node numbers in the same frequency in sequence from
node number 1 up to the number of connected nodes. Before registering, start
up all the connected I/O Slave Stations in RUN mode.

Scan List Registration
with Serial Number Check
Enabled
The serial number is registered at the same time as the corresponding I/O
Slave Station. The serial number is the product’s unique number, i.e., no two
serial numbers are the same. This setting has the advantage of preventing
mistaken Slave recognition even if a WT30 Terminal with the same channel
(frequency), same node number, and same model is in the radio signal range.
The disadvantage is that I/O Slave Stations that are replaced must be re-registered.
When the serial number check is enabled (bit 9 is ON), the I/O Slave Station’s
serial number is registered in the Serial Master Station.
ON
Bit 9: ON (serial number check enabled)

The serial number is not registered when the scan list is registered. This setting has the advantage of not requiring I/O Slave Stations to be re-registered
from the Serial Master Station after replacement. The disadvantage is that
mistaken Slave recognition may occur if a WT30 Terminal with the same
channel (frequency), same node number, and same model is in the radio signal range.

the I/O Slave Stations, or the node numbers are not assigned sequentially, or
if the I/O Slave Stations are not within the radio signal range. Use the following settings to stop scan list registration if required. When registration of all I/O

Scan List Enabled/Disabled Mode
The scan list enabled/disabled mode is set during RUN mode. In scan list
enabled mode, communications are performed with the specified, registered
communications partners. In scan list disabled mode, communications are
performed without registering any communications partners.
1. Scan list registration is not required: Use scan list disabled mode
2. Scan list registration without serial number check is required: Use scan list
enabled mode
3. Scan list registration with serial number check is required: Use scan list
enabled mode
Scan List Disabled Mode
52
In scan list disabled mode, communications are performed without registering
I/O Slave Stations starting from the node number 1 specified at the Serial
Master Station up to the specified number of nodes. Scan list registration is
not required in this mode, and I/O Slave Stations can be added and replaced
using switch settings only. I/O Slave Stations are detected again, however,
when a power interruption occurs at the Serial Master Station. Therefore, the
Serial Master Stations cannot determine whether I/O Slave Stations have
been changed (connecting a different model to the same node number). Even
if only the power to the I/O Slave Station has been interrupted, a different station will not be detected.

In scan list enabled mode, the scan list must be registered. If scan list registration is performed without the serial number check, I/O Slave Stations can
be replaced by simply setting the switches. Scan list registration must be performed again when an I/O Slave Station is added regardless of whether the
serial number check is enabled, and also when replacing I/O Slave Stations if
the serial number check is enabled. The Serial Master Station performs wireless communications only with the I/O Slave Stations registered in the scan
list, preventing unwanted I/O Slave Stations from joining the network. If the
serial number check is disabled, replacement of the same node number with
the same model will not be detected.

Input Hold
In normal mode, input data is read, and sent to the Serial Master Station as is.
The input data is saved according to the polling timing from the Serial Master
Station. For example, after an input turns ON, if the input from the Serial Master Station turns OFF during polling, the input OFF data is transmitted to the
Serial Master Station and the ON data input in the I/O Slave Station is not correctly transferred.
53
Section 3-6
Function Setting Switch
When the input hold is set, the ON data that has been input in the I/O Slave
Station is held until it is sent to the Serial Master Station. Therefore, ON data
that has been input can be sent accurately to the Serial Master Station. Up to
two polling cycles are required for the input terminal status to be reflected.
Communications Timing with the Personal Computer or PLC
In normal mode, when the signal from the input terminal is shorter than one
polling cycle, the ON signal may not be received by the Serial Master Station,
depending on the polling timing. When the input hold is set, the ON signal is
held for twice the polling cycle time. Read the data from the Serial Master Station using this timing. For details on calculating the polling cycle, refer to Wireless Communications Delay (TWCY) on page 100.
The length is
approximately TWCY = 10 ms × n stations. Commands are sent to the Serial
Master Station from the personal computer or PLC, and the response is
received within 50 ms. Allow a command interval that is less than two polling
cycles, as shown below.
(Command send time + Wait time (approx. 50 ms) + Response receive
time) < Two polling cycles
If a small number of I/O Slave Stations is used, the polling cycle will be shortened, and the time for a response to be received after sending the command
to the personal computer or PLC may be exceed two polling cycles. In the following polling cycle, the requested data will be deleted and overwritten by the
next data. Determine whether communications are valid, referring to the table
on the following page.

If inputs are turned ON multiple times while data is being sent to the Serial
Master Station, the data will be cleared after being held for two polling cycles.
Note
Polling refers to the operation in which I/O Data is sent and received for each
I/O Slave Station when communications are performed between a single
Serial Master Station and multiple I/O Slave Stations. The cycle time refers to
the time required for communications to be completed with all I/O Slave Stations.
The following example provides an explanation for the holding time while in
input hold mode (two polling cycles in the table), with a communications baud
rate of 9,600 or 38,400 bps.

The shaded area indicates the combinations for which communications are

Example 1: When 5 stations are connected, and a baud rate of 38,400 bps is
used, two polling cycles are 100 ms > 71 ms (personal computer/PLC communications time). Therefore, data can be read.
If communications are performed at 9,600 bps, however, the two polling
cycles will be 131 ms, and communications will not be able to be performed
within the two polling cycles. Refer to the above table and consider the serial
baud rate and number of connected stations when creating the program.

Output Control for Communications Errors
Select whether to hold or clear data when a communications error occurs.
This function is enabled at the Serial Master Station for the input status from
the I/O Slave Station, and at the I/O Slave Stations for the output commands
from the Serial Master Station.
For example, when an input of the I/O Slave Station is ON, the ON data is
transmitted to the Serial Master Station provided that communications are
normal. If a communications error occurs and the WT30 Terminal is set to
hold I/O status data if a communications error occurs, the data held in the
Serial Master Station turns ON. If the WT30 Terminal is set for data to be
cleared if a communications error occurs, the data held by the Serial Master
Station will be cleared to OFF.

Relay Function
The relay function extends the communications distance using an I/O Slave
Station as a Relay Station. Even if equipment is relocated, making communications between the Serial Master Station and I/O Slave Stations unstable or
resulting in a disconnection, the communications path can be switched,
enabling communications to continue automatically via a Relay Station.

Using WT30 Terminal as a Relay Station
Extending
Communications Distance
When the Serial Master Station and I/O Slave Stations are separated by a
long communications distance, communications with stations for which radio
waves are difficult to reach can be made possible with the use of a Relay Station. I/O Slave Stations are also registered through the Relay Station. Only a
single Relay Station can be used, but up to 64 I/O Slave Stations can be connected to the Relay Station.

CompoWay/F is used as the communications protocol. Command frames are
sent to the WT30 from the host, these commands are processed by the
WT30, and response frames are returned to the host.
6-1-1
Command Frame Structure
Addresses, response codes, and end codes are all expressed in hexadecimal.
If a value is followed by H (e.g., 02H), the value is a hexadecimal number. Values expressed as normal numerical values are in ASCII. The values under the

The I/O size data that is read depends on the setting status at the time the
data is read, as follows.
• In RUN mode without using the scan list: Reads I/O size of I/O Slave Stations that entered the network using entry processing.
• In SET mode with all I/O Slave Stations registered: Reads I/O size of I/O
Slave Stations during temporary registration in the scan list.
• Other setting status: Reads I/O size of I/O Slave Stations registered in the
scan list.

I/O Response Time
I/O Response Time
Compared with a wired network, wireless communications may be delayed due to the influence of the surrounding electromagnetic environment, making it difficult to achieve the calculated response time. The calculation method is provided here as a guide.
The response time required until an input signal from the I/O Slave Station reaches the personal computer or
PLC via the Serial Master Station can be estimated as follows:
T1: I/O Slave Station input filter (10 ms/100 ms)
T2: Serial Master Station wireless communications delay (TWCY) × 2
T3: The CompoWay/F command and response execution time and the time required for the Serial Master Station to return a response. This value depends on the communications baud rate and number of data.

I/O Response Time
Appendix C
Wireless Communications Delay (TWCY)
The response time required until an input signal from the I/O Slave Station is reflected in the Serial Master Station’s memory is a total of approximately 10 ms per I/O Slave Station plus the input filter time, as follows:
Response time = TWCY × 2 (See note 1.) + Input filter (See note 2.) ( = T1 + T2)
Note
(1) The wireless communications delay is multiplied by two to account for the internal processing of the
Serial Master Station (time required until data is stored in the memory area).
(2) The input filter is 10 ms or 100 ms (depending on the switch setting).
TWCY
= WNODE
Σ (Sum total of cycle times for all I/O Slave Stations)
= WNODE
Σ (10 ms × n stations)
Using Relay Stations
The wireless communications delay is doubled when a Relay Station is used.
= WNODE
Σ (10 ms × n stations × 2)
Example 1: Using one Master Station, four I/O Slave Stations, and an input filter of 10 ms.
10 × 4 × 2 + 10 = 90 ms
Example 2: Using one Master Station, one Relay Station, four I/O Slave Stations, and an input filter of 10 ms.
10 × 4 × 2 × 2 + 10 = 170 ms
The calculations shown here indicate theoretical values and should be considered as a rough guide only. The
actual values obtained will depend on the installation environment.
