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 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.

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 Sta-

tion 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 sim-

ply 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 termi-

nal 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 General-

purpose 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 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).

Fe a t 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.

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.

Installation Section 2-1

2-1 Installation

Make sure that the radio wave conditions at the installation site are favorable

before actually installing the WT30 Terminals.

2-1-1 Installation location

Do not install this device in locations such as the following:

• Areas exposed to direct sunlight

• Areas with extremely high humidity

• Near devices such as televisions, radios, and computers

• Near devices that emit sparks, such as motors, drills, and welding equip-

ment

• Near strong magnets

• Near fluorescent lights

• Inside metal panels or locations surrounded by metal or concrete

If the WT30 Terminal is installed in a metal panel, be sure to mount the entire

Antenna outside the panel where there are no interfering objects.

2-1-2 Installation Precautions

• Install the Antennas for the Serial Master Station and I/O Slave Stations

or the Relay Stations and I/O Slave Stations in parallel.

• Install the Antennas as far away as possible from and not parallel to elec-

tric wires or metal panels.

• Use wood screws when installing the WT30 on a wooden surface.

• Use M4 screws for installation if the provided installation screws are not

used.

• Communications are not possible if the Terminals is too close to each

other (within 1 m). Make sure that sufficient distance is provided between

WT30 Terminals.

2-1-3 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 posi-

tion 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 impor-

tant point for communications at long distances (e.g., exceeding 50 m or

60 m.)

Transmitting

Antenna Obstacle

Area not in a direct line of

sight from the Antenna

Antenna that is

Installation Section 2-1

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 Anten-

nas, 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.

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 Anten-

nas 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 in-

crease in the number of retries, and a reduction in the possible communi-

cations 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 pos-

sible, 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 orien-

tation, 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 pos-

sible 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 sys-

tems.

• Separate the Antennas and ID Tags by at least 3 m.

• Set the frequency to a channel other than channels 12 to 30 or chan-

nels 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 “di-

rectional characteristics.” The directional characteristics for Pencil Anten-

nas 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 commu-

nications distance will be shortened if the tips of the Antennas for both the

WT30 Terminals are installed facing each other.

Installation Section 2-1

11. Other Points about Magnet-base Antennas

• The magnet on the Magnet-base Antenna is very strong. Do not re-

move the Antenna by pulling on the cover or cable. Doing so may dam-

age 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 pro-

tected.

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 ob-

jects. 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.

2-1-4 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.

2-3 Wireless System Design Considerations

2-3-1 Construction of Multiple Wireless Systems

When constructing a system for using multiple Serial Master Stations, the fol-

lowing 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 interfer-

ence 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 dia-

gram. 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 chan-

nels 13 and 14. Therefore, the channel with the frequency following chan-

nel 1 is channel 51. Channels 5, 9, 51, and 63 can be used without

interference. For details on frequencies, refer to Appendix F Frequency Ta-

ble on page 105.

WT30

ERRP

Load

WT30

ERRN

Load

Wireless System Design Considerations Section 2-3

Do not select the frequencies of radio waves created by intermodulation.

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 inter-

ference. 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 intermodula-

tion resulting in transmission delays. To eliminate the influence of intermodu-

lation, 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.

frequencies, and new waves will be generated with frequencies at intervals equal to the intervals

Scan List Section 3-1

3-1 Scan List

Communications are divided into two types depending on whether the com-

munications partner (I/O Slave Station) is registered or unregistered. Regis-

tration 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.

For details on using unregistered slave stations, refer to 3-4 Using Unregis-

tered Communications Partners and for using registered slave stations, refer

to 3-5 Registering the Communications Partner.

Unregistered Slaves Registered Slaves

Mistaken recognition will occur if an I/O

Slave Station set with the same node

istered I/O Slave Stations only. Therefore,

mistaken recognition will not occur. Com-

munications are also only performed with

the specified I/O Slave Stations, thereby

eliminating unnecessary polling and

heightening security.

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 sup-

ported provided that the same frequency

channel is not already being used nearby,

and that the operation on a different fre-

quency channel can be confirmed.

By registering the I/O Slave Station with

the serial number check enabled, re-reg-

istration at the Serial Master Station is

required when an I/O Slave Station is

replaced.

Monitoring Unused Frequencies Section 3-2

3-2 Monitoring Unused Frequencies

The peak value of the received signal strength in the frequency band being

used is monitored onsite, enabling selection of available channels (frequen-

cies).

3-2-1 Wireless Channel Monitor for Specified Channels

The actual received signal strength for the channel specified using the chan-

nel setting switch can be monitored in realtime using the display.

1,2,3... 1. Before turning ON the power, set the function setting switch as follows:

2. Set the frequency channel to be monitored using the channel setting

switch (WCH switch).

3. Set the mode setting switch to TEST mode, and turn ON the power. The

MS and WS indicators will flash green.

4. The monitoring results are displayed using the 10 levels of the RSSI (re-

ceived signal strength indicator).

5. The received signal strength is indicated using 10 levels according to the

frequency monitoring results obtained by setting the channel setting

switch. The monitoring results are not recorded in the EEPROM.

Monitoring Unused Frequencies Section 3-2

3-2-2 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 auto-

matically recorded in EEPROM. (All channels are level 0 in the default set-

tings.) 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 val-

ues.

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 To change the installation position of the WT30 Terminal if the surrounding

radio wave conditions change, the recorded peak values for the received sig-

nal strength must be cleared to enable an accurate reading of the surrounding

radio wave conditions. Clear the recorded data and then start a new auto-

matic scan.

1,2,3... 1. Before turning ON the power, set the function setting switch as follows:

2. Change the mode setting switch setting to TEST mode and turn ON the

power. The MS/WS indicators will flash green.

The automatic scan will start for all channels. The automatic scan will start

from the specified channel, proceed sequentially up to channel 83, and

then return to channel 1. Scanning will continue until the power is turned

OFF (for the total 67 channels).

corded). Automatic scanning will continue.

Automatic scanning executes a single scan for each channel. Radio waves

may be received from channels for which the automatic scan has been

completed. Therefore, executing the automatic scan for longer periods of

time, and not for just a single cycle, is recommended.

4. Specify the channel to be monitored using the channel setting switch.

3-5-2 Registering Communications Partners (All I/O Slave Stations)

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

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.

Note 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).

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 Sta-

tions by specifying the I/O Slave Station node numbers individually. When reg-

istering 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.

Registering All I/O Slave Stations Automatically

All the I/O Slave Stations up to the highest node number are registered.

Registering Specified I/O Slave Stations

The I/O Slave Station for the node number specified at the Serial Master Sta-

tion is registered. Set the special function switch from OFF to ON, and then

OFF again.

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-reg-

istered.

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.

Scan List Registration

with Serial Number Check

Disabled

The serial number is not registered when the scan list is registered. This set-

ting 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 sig-

nal range.

When the serial number check is disabled (bit 9 is OFF), the I/O Slave Sta-

tion’s serial number is not registered.

3-6-2 Stopping Registration of All I/O Slave Stations

Scan list registration cannot be completed if the power is not turned ON for all

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 follow-

ing settings to stop scan list registration if required. When registration of all I/O

Slave Stations is stopped, scan list details will not be written to EEPROM

unless this operation is performed.

3-6-3 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

Scan List Disabled Mode 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 sta-

tion will not be detected.

Scan List Enabled Mode In scan list enabled mode, the scan list must be registered. If scan list regis-

tration is performed without the serial number check, I/O Slave Stations can

be replaced by simply setting the switches. Scan list registration must be per-

formed 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 wire-

less 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.

3-6-4 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 Mas-

ter 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 cor-

rectly transferred.

Function Setting Switch Section 3-6

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 Sta-

tion using this timing. For details on calculating the polling cycle, refer to Wire-

less 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 short-

ened, 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 fol-

lowing 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 Sta-

tions.

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.

List of Communications Cycle Times

Note The shaded area indicates the combinations for which communications are

enabled.

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 com-

munications 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.

3-6-6 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 Section 4-1

4-1 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 communi-

cations 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.

4-1-1 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 Sta-

tion. 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 con-

nected to the Relay Station.

Note The I/O terminals and error output terminal settings on the I/O Slave Station

being used as the Relay Station are disabled. If an I/O Slave Station is within

the communications range for the Serial Master Station, communications with

the Serial Master Station can be performed directly even if a Relay Station is

installed. Relays are supported for only one stage, i.e., only for one Relay Sta-

tion.

keep the network in its optimal operating condition.

• Wipe the WT30 Terminal daily with a dry, soft cloth.

• When a spot cannot be removed with a dry cloth, dampen the cloth with a

neutral cleanser (diluted to 2%), wring out the cloth, and wipe the WT30

Terminal.

• A smudge may remain on the WT30 Terminal from gum, vinyl, or tape that

was left on for a long time. Remove the smudge when cleaning.

!Caution Never use volatile solvents such as paint thinner, benzene, or chemical wipes.

These substances could damage the surface of the WT30 Terminal.

5-2-2 Inspection

Be sure to inspect the system periodically to keep it in its optimal operating

condition. In general, inspect the system once every 6 to 12 months, but

inspect more frequently if the system is used at high temperatures or humidity

or under dirty/dusty conditions.

Inspection Equipment Prepare the following equipment before inspecting the system.

Required Equipment • Standard and Phillips screwdrivers

• Multimeter (or digital volt meter)

• Alcohol and all-cotton cloth

Equipment Required

Occasionally

• Synchroscope

• Thermometer, hygrometer

Inspection Procedure Check the items in the following table to make sure that the WT30 Terminal

meets the standard.

If the WT30 Terminal does not meet the required standards, improve the sur-

rounding environment so that the standards are met or adjust the WT30 Ter-

minal.

Precautions

Observe the following precautions when replacing a WT30 Terminal found to

be faulty during inspection or by other means.

• After replacement make sure there are no errors with the new WT30 Ter-

minal.

• When a WT30 Terminal is being returned for repair, attach a sheet of

paper detailing the problem and return the WT30 Terminal to your

OMRON representative.

• If there is a faulty contact, try wiping the contact with a clean, all-cotton

cloth dampened with alcohol.

!Caution To prevent electric shock when replacing a WT30 Terminal, be sure to turn

OFF the power supplies before removing the faulty WT30 Terminal.

5-3 Replacing WT30 Terminals

The procedure for replacing I/O Slave Stations registered in the scan list is

explained here. When replacing I/O Slave Stations that are not registered in

the scan list, registration at the Serial Master Station is not required. Before

replacing the I/O Slave Station, set the node number, frequency channel, and

function setting switch. Then, either cycle the Serial Master Station power or

change the mode setting switch.

5-3-1 I/O Slave Station Replacement Procedure

I/O Slave Station Settings

1,2,3... 1. Before turning ON the power, set the function setting switch to the same

setting used before replacement.

2. Set the node number of the I/O Slave Station using the node setting switch.

3. Set the frequency channel using the channel setting switch.

4. Change the setting for the mode setting switch to RUN mode, and then turn

ON the power.

Settings

When the I/O Slave Station being set is registered in the Serial Master Station

(scan list registration), the I/O Slave Station must be re-registered in the Serial

Master Station after replacement, regardless of whether the serial number

check is enabled or disabled. Re-registration is not required, however, if the

serial number check is disabled and the model is the same as that being

replaced. To automatically register all I/O Slave Stations, turn OFF bit 8 of the

function setting switch (automatically register all I/O Slave Stations).

1,2,3... 1. Before turning ON the power, set the function setting switch on the Serial

Master Station as follows:

2. Set the node number of the I/O Slave Station to be connected using the

node setting switch.

3. Set the frequency channel using the channel setting switch.

4. Change the mode setting switch to SET mode, and then turn ON the pow-

er.

5. Set the special function switch as follows:

6. The WS indicator will change from flashing green to being lit green when

scan list registration is completed.

7. Change the mode setting switch to RUN mode.

Frame Structure Section 6-1

6-1 Frame Structure

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. Val-

ues expressed as normal numerical values are in ASCII. The values under the

frame are the numbers of bytes.

6-1-2 List of Services

STX A code, 02 hex, indicating the beginning of a communications

frame (text). This code must always be set as the first byte.

When STX is received again during reception, reception is

executed again from the point where STX was received.

Unit No. Identifies the unit number (UNIT No.) of the Serial Master Sta-

tion.

• A BCD value between 00 to 99 can be set.

• No response will be returned for stations with unit numbers

outside the above range.

Subaddress Always set to 00.

SID (Service ID) Always set to 0.

Command text Application layer (service request/response PDU).

MRC Indicates the main request code. Refer to 6-1-2 List

of Services on page 76.

SRC Indicates the sub request code. Refer to 6-1-2 List of

Services on page 76.

ETX A code, 03 hex, indicating the end of text.

BCC The block check character. The value is an exclusive OR of all

data from the unit number to the ETX for each byte.

MRC SRC Name of service Processing

01 01 Read Variable Area This service reads from variable areas.

01 02 Write Variable Area This service writes to variable areas.

05 01 Read Controller Data This service reads the model number

and version codes.

Frame Structure Section 6-1

No services will be accepted and no responses will not be returned while the

WT30 is in initial status (status until initialization is finished) or if a memory

error (RAM error) has occurred.

BCC Calculation Example

The BCC (Block Check Character) is determined by calculating the exclusive

OR of the individual bytes from the node number up to ETX. The 8-bit result is

written to the BCC byte at the end of the frame.

6-1-3 Response Frame

• An end code is returned for each command frame received that was

addressed to the local node.

• No response will be returned unless the frame contained all elements up

to the ETX and BCC.

I/O Response Time

Compared with a wired network, wireless communications may be delayed due to the influence of the sur-

rounding electromagnetic environment, making it difficult to achieve the calculated response time. The calcula-

tion 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 Sta-

tion to return a response. This value depends on the communications baud rate and number of data.

TOUT: I/O Unit output ON (OFF) delay time

TCMD: Command send time

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 Sta-

tion’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 = (Sum total of cycle times for all I/O Slave Stations)

= (10 ms × n stations)

Using Relay Stations

The wireless communications delay is doubled when a Relay Station is used.

= (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.
