2Fe a t ur e s Section 1-11-1 FeaturesInformation on systems using WT30 FA Wireless SS Terminals (also referredto as WT30 or WT30 Terminals in this manual) is provided here.1-1-1 OverviewThe 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 datausing 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/Oterminals can also be connected to a DeviceNet-compatible WD30 Master. Simple Relay Functions The relay functions enable an increase in the communications area. TheWT30 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 AreaChanging frequencies removes interference between different sets installed inthe same area. This enables you to construct a wireless system consisting ofup to 10 sets (depending on the installation environment).Advantage of Full Range of ChannelsSupporting up to 67 channels, you can construct multiple systems withoutinterference caused by intermodulation.Easy Installation and SettingsDIN Rail mounting makes installation easy. The system can be registered sim-ply by setting the switches on the WT30 Terminal, so Support Software is notrequired.I/O Slave Stations with Built-in I/OI/O Slave Stations are available in three types: With 16 inputs (DC inputs), 8inputs/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 theSerial Master Station enables communications to be performed with specifiedI/O Slave Stations only.Determine Operating Status from the LED DisplayThe LED display on the WT30 Terminal can be used to check the WT30'serror status, whether wireless communications are normal, and the receivedsignal strength.Path Switching Function Communications will continue via the Relay Station even if communicationswith the Serial Master Station and I/O Slave Station are unstable, or if the I/OSlave Station is removed.Antennas (Optional) Three antenna types are available: Magnet-base Antennas, Flat Antennas,and Pencil Antennas.Compatible with General-purpose RS-232C InterfaceA CompoWay/F command must be created to read (write) ON/OFF or otherdata. By using the OMRON Function Block Library, PLC users can reduce theamount of programming required.Supported in OMRON Function Block Library for SYSMAC CS/CJ-series PLCsThe 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 viathe WT30-M01-FLK Serial Master Station connected to the PLC. Using theOMRON 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 FBLibrary Start-Up Guide (Cat.

14Installation Section 2-12-1 InstallationMake sure that the radio wave conditions at the installation site are favorablebefore actually installing the WT30 Terminals.2-1-1 Installation locationDo 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 concreteIf the WT30 Terminal is installed in a metal panel, be sure to mount the entireAntenna 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 Stationsor 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 notused.• Communications are not possible if the Terminals is too close to eachother (within 1 m). Make sure that sufficient distance is provided betweenWT30 Terminals.2-1-3 Determining the Antenna Installation PositionThe WT30 uses radio waves with a frequency of 2.4 GHz, which is very high.High-frequency waves exhibit strong rectilinear propagation and are reflectedeasily. 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 betweenthem.High-frequency waves, which exhibit strong rectilinear propagation, areused and so it is difficult for the waves to reach areas that are not in a directline 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 or60 m.)TransmittingAntenna ObstacleArea not in a direct line ofsight from the AntennaAntenna that isdifficult for the wavesto reachAntenna thatwaves will reach
15Installation Section 2-1If the Antennas are installed in locations with relatively high ceilings and alot 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, communicationsmay 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 inhigh locations, because the space surrounding the Antennas will be moreopen, there will be less influence from obstacles, and the radio waves willpropagate 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 ofradio wave propagation), the radio waves may not be propagated due tothe influence of the objects. Metal objects have the greatest influence asthey reflect radio waves, whereas glass and plastic objects allow the wavesto 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 AntennasLoss occurs in the cable when using WT30-AT001 Magnet-base Antennas.Therefore, the maximum communications distance is approximately 50 mindoors, which is shorter than for Pencil Antennas.5. Cable Bending RadiusThe minimum bending radius for WT30-AT001 Magnet-base Antennas is38 mm. Also, do not bend the cable at points less than 34 mm from the endconnected to the WT30 Terminal or at points less than 40 mm from the endconnected to the Antenna.The minimum bending radius for WT30-AT002 Flat Diversity Antennas is50 mm. Also, do not bend the cable at points less than 23 mm from the endconnected to the WT30 Terminal or at points less than 20 mm from the endconnected to the Antenna.High AntennaObstacleRadio wave energy23R50WT30-AT002 Flat Diversity AntennaCable Bending Radius and Dimensions34R382040WT30-AT001 Magnet-base Antenna(Unit: mm)
16Installation Section 2-16. Separate different sets of Antennas as much as possible.If different sets of Antennas are close to each other, they will influenceeach 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 ifpossible.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 beutilized. 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 inthe 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 therange used by the WT30 Terminals. Therefore, if the two systems are usedon 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 AntennasAntennas emit waves in certain directions, and there are certain directionsin 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 aredonut-shaped, spreading outwards horizontally. Radio waves are emittedin 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 theWT30 Terminals are installed facing each other.
17Installation Section 2-111. 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 AntennasFlat Diversity Antennas also have directional characteristics, in the sameway as Magnet-base Antennas.

18Installation Section 2-113. 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 measuresto protect the Antenna. Subjecting the Antenna to strong shock may causeeither external or internal damage to the Antenna. Internal damage that isnot necessarily externally visible may prevent communications, such asbroken wires.2-1-4 Flat Diversity AntennasSecure the Flat Diversity Antenna to the Mounting Bracket with screws. TheMounting Bracket includes a magnet for attachment to metal surfaces. Do nottighten the vertical and horizontal angle adjustment knobs at first to allowadjustment of the Antenna position and angle. After adjusting to the correctposition, tighten the knobs securely.

32Wireless System Design Considerations Section 2-3Connecting to Error OutputPNP OutputNPN Output2-3 Wireless System Design Considerations2-3-1 Construction of Multiple Wireless SystemsWhen 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 forthe wireless channels. (Radio interference can be handled by retry processesbetween the wireless networks, but will lengthen the system response time.)The WT30 supports 67 wireless channels from which to select. As a roughguide, however, a maximum of 10 wireless systems can be used in a singlearea without radio interference on account of the following considerations.1,2,3... 1. Do not select neighboring wireless channels as they have a large amountof interference.2. Due to the fundamental nature of radio waves, if two or more waves withdifferent frequencies are output at exactly the same time, mutual interfer-ence will occur between the different frequencies, and new waves will begenerated with frequencies at intervals equal to the intervals between theoutput frequencies. (This phenomenon is called intermodulation.)For example, if channels 5 and 9 are used, electromagnetic interferencewill 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 ofchannel 51 is located between the frequencies for channels 1 and 2, andthe 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 withoutinterference. For details on frequencies, refer to Appendix F Frequency Ta-ble on page 105.VGWT30ERRPLoadVGWT30ERRNLoad
33Wireless System Design Considerations Section 2-3Do not select the frequencies of radio waves created by intermodulation.Antenna Separation DistanceThe distance between WT30 Terminals has a large influence on the amountof interference received. In particular, there may often be cases where SerialMaster Stations are installed relatively closely to each other. Separate theAntennas 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 SerialMaster Station and I/O Slave Station to check the interference.2-3-2 Communications Errors Caused by IntermodulationCommunications 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 tofrequencies at regular intervals.2-3-3 Serial Master Station Input/Output DataThe Serial Master Station’s input/output data is cleared by turning OFF thepower. After turning ON the power, an output signal of all zeros (OFF) is sentto the output of the I/O Slave Stations from the Serial Master Station.I/O Slave StationChannel 51 Channel 63I/O Slave StationFrequencyf1 = Channel 5 f2 = Channel 9Serial Master Station Serial Master Station Radio wave createdby intermodulationRadio wave createdby intermodulationf1 - (f2 - f1) = Channel 1 f2 + (f2 - f1) = Channel 13Due 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.Intermodulation(1) At power OFF: All I/O data cleared.Serial Master StationI/O Slave Station(3) Output signal: All "0"(2) AT power ON: Sends all "0" output signal.

36Scan List Section 3-13-1 Scan ListCommunications 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. Themode for communications with specified, registered communications partnersis referred to as scan list enabled mode. The mode for communicationsbetween the Serial Master Station and unregistered I/O Slave Stations fromthe specified node number 1 up to the specified number of nodes is referredto 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, referto 3-5 Registering the Communications Partner.Unregistered Slaves Registered SlavesMistaken 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.Communications are performed with reg-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.WT30 Serial Master StationWT30 Serial Master StationWT30I/O Slave StationNode No. 2WT30I/O Slave StationNode No. 1WT30I/O Slave StationNode No. 2WT30I/O Slave StationNode No. 1• Communications with Unregistered Communications Partner (Scan List Disabled Mode)• Communications with Registered Communications Partner (Scan List Enabled Mode)EEPROMNo. 1Add or replace WT30 Terminals easily Not registered RegisteredPLC PLC
37Monitoring Unused Frequencies Section 3-23-2 Monitoring Unused FrequenciesThe peak value of the received signal strength in the frequency band beingused is monitored onsite, enabling selection of available channels (frequen-cies). 3-2-1 Wireless Channel Monitor for Specified ChannelsThe 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 settingswitch (WCH switch).3. Set the mode setting switch to TEST mode, and turn ON the power. TheMS 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 thefrequency monitoring results obtained by setting the channel settingswitch.

38Monitoring Unused Frequencies Section 3-23-2-2 Monitoring All Wireless ChannelsThe received signal strength for all wireless channels is automaticallyscanned (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 orwhen automatic scanning is stopped. Approximately 70 seconds is required toread the received signal strength for all channels. The automatic scan statuscan be confirmed using the WS indicator. In the first cycle, the WS indicatorflashes green, and from the second and subsequent cycles, the WS indicatoris 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 readdata collected onsite from an office, for example, the data must be read whenautomatic scanning is stopped.Note To change the installation position of the WT30 Terminal if the surroundingradio wave conditions change, the recorded peak values for the received sig-nal strength must be cleared to enable an accurate reading of the surroundingradio 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 thepower. The MS/WS indicators will flash green.The automatic scan will start for all channels. The automatic scan will startfrom the specified channel, proceed sequentially up to channel 83, andthen return to channel 1. Scanning will continue until the power is turnedOFF (for the total 67 channels).1234ON567890Bit 4: OFF (field strength monitor enabled)Bit 5: ON (automatically select all channels)WSMSMS: Module status indicator WS: Wireless status indicator SETTESTRUN
39Monitoring Unused Frequencies Section 3-23. The WS indicator will change from flashing green to being lit green whenthe automatic scan completes one cycle (the received signal strength is re-corded). Automatic scanning will continue. Automatic scanning executes a single scan for each channel. Radio wavesmay be received from channels for which the automatic scan has beencompleted. Therefore, executing the automatic scan for longer periods oftime, and not for just a single cycle, is recommended.4. Specify the channel to be monitored using the channel setting switch.5. The peak value for the recorded received signal strength is displayed usingthe 10 levels indicated by the RSSI. Reading the Recorded Received Signal Strength after Stopping the Automatic ScanThis operation is used to monitor the peak value after first stopping the auto-matic scan temporarily so that the recorded received signal strength peak val-ues will not be overwritten.1,2,3... 1. Set the function setting switch as shown below and change the setting ofthe mode setting switch from RUN mode to TEST mode. The MS indicatorwill flash green.2.

47Registering the Communications Partner Section 3-53-5-2 Registering Communications Partners (All I/O Slave Stations)Register I/O Slave Stations at the Serial Master Station. The Serial MasterStation performs wireless communications only with those I/O Slave Stationsthat are registered. This prevents unwanted I/O Slave Stations from joiningthe network. When registering, the serial number check can also be enabledor disabled. Serial number recognition is the function that writes the I/O SlaveStation’s unique number to the Serial Master Station.Scan List Registration with Serial Number CheckThe serial number is registered at the same time as the corresponding I/OSlave Station. This function has the advantage of preventing mistaken Slaverecognition even if a WT30 Terminal with the same channel (frequency), samenode number, and same model is in the radio signal range. The disadvantageis that I/O Slave Stations that are replaced must be re-registered.

This enablescommunications to be performed with specified communications partners. Setthe operation mode to SET mode.

51Function Setting Switch Section 3-6Select to either register all I/O Slave Stations automatically by specifying thehighest 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 fromnode number 1 up to the number of connected nodes. Before registering, startup all the connected I/O Slave Stations in RUN mode. Registering All I/O Slave Stations AutomaticallyAll the I/O Slave Stations up to the highest node number are registered.Registering Specified I/O Slave StationsThe 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 thenOFF again. Scan List Registration with Serial Number Check EnabledThe serial number is registered at the same time as the corresponding I/OSlave Station. The serial number is the product’s unique number, i.e., no twoserial numbers are the same. This setting has the advantage of preventingmistaken 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’sserial number is registered in the Serial Master Station. Scan List Registration with Serial Number Check DisabledThe 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-registeredfrom the Serial Master Station after replacement. The disadvantage is thatmistaken Slave recognition may occur if a WT30 Terminal with the samechannel (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 StationsScan list registration cannot be completed if the power is not turned ON for allthe I/O Slave Stations, or the node numbers are not assigned sequentially, orif 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/OSlave Stations is stopped, scan list details will not be written to EEPROMunless this operation is performed. 1234ON567890Bit 8: OFF (register all I/O Slave Stations automatically)1234ON567890Bit 8: ON (register specified I/O Slave Stations)1234ON567890Bit 9: ON (serial number check enabled)1234ON567890Bit 9: OFF (serial number check disabled)

The RSSI’s green indica-tors will flash 4 or 5 times to indicate that the operation has been completed.3-6-3 Scan List Enabled/Disabled ModeThe scan list enabled/disabled mode is set during RUN mode. In scan listenabled mode, communications are performed with the specified, registeredcommunications partners. In scan list disabled mode, communications areperformed without registering any communications partners.1. Scan list registration is not required: Use scan list disabled mode2. Scan list registration without serial number check is required: Use scan listenabled mode3. Scan list registration with serial number check is required: Use scan listenabled modeScan List Disabled Mode In scan list disabled mode, communications are performed without registeringI/O Slave Stations starting from the node number 1 specified at the SerialMaster Station up to the specified number of nodes. Scan list registration isnot required in this mode, and I/O Slave Stations can be added and replacedusing switch settings only. I/O Slave Stations are detected again, however,when a power interruption occurs at the Serial Master Station. Therefore, theSerial Master Stations cannot determine whether I/O Slave Stations havebeen changed (connecting a different model to the same node number). Evenif only the power to the I/O Slave Station has been interrupted, a different sta-tion will not be detected. ENTERONOFF OFF → ON → OFFRSSI display: Green indicators flashing
53Function Setting Switch Section 3-6Scan List DisabledSet the function setting switch as follows (Serial Master Station only):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 canbe 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 theserial number check is enabled, and also when replacing I/O Slave Stations ifthe serial number check is enabled. The Serial Master Station performs wire-less communications only with the I/O Slave Stations registered in the scanlist, preventing unwanted I/O Slave Stations from joining the network. If theserial number check is disabled, replacement of the same node number withthe same model will not be detected.Scan List EnabledSet the function setting switch as follows (Serial Master Station only):3-6-4 Input HoldIn 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 MasterStation. 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 theSerial Master Station and the ON data input in the I/O Slave Station is not cor-rectly transferred.Serial Master StationNew nodes added as required.Normal communicationsWT30-M01-FLK ANT1ANT2I/O Slave StationsNode No. 1 Node No. 2 Node No. 3 Simply set the frequency channel and node number to easily add any model to the network.Set to the estimated maximum number of nodes for the system.Example: 5 nodesNode No. 4WT30-SID16ANT1ANT2WT30-SID16ANT1ANT2WT30-SID16ANT1ANT2WT30-SID16ANT1ANT21234ON567890Bit 2: OFF (scan list disabled)1234ON567890Bit 2: ON (scan list enabled)
54Function Setting Switch Section 3-6When the input hold is set, the ON data that has been input in the I/O SlaveStation is held until it is sent to the Serial Master Station. Therefore, ON datathat has been input can be sent accurately to the Serial Master Station. Up totwo polling cycles are required for the input terminal status to be reflected.Communications Timing with the Personal Computer or PLCIn normal mode, when the signal from the input terminal is shorter than onepolling 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 isheld 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 isapproximately TWCY = 10 ms × n stations. Commands are sent to the SerialMaster Station from the personal computer or PLC, and the response isreceived within 50 ms. Allow a command interval that is less than two pollingcycles, as shown below.(Command send time + Wait time (approx. 50 ms) + Response receivetime) < Two polling cyclesIf 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 commandto 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 thenext data. Determine whether communications are valid, referring to the tableon the following page. If inputs are turned ON multiple times while data is being sent to the SerialMaster 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 eachI/O Slave Station when communications are performed between a singleSerial Master Station and multiple I/O Slave Stations. The cycle time refers tothe 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 ininput hold mode (two polling cycles in the table), with a communications baudrate of 9,600 or 38,400 bps.One polling cycle One polling cycleInput holdPolling local nodeInput terminalSerial Master Station variable area (Slave Station input data)Serial Master StationI/O Slave Station input signalCommandSerial Master Station response wait time (approx. 50 ms)ResponseCommandResponsePC/PLC request commandTWCY TWCYONPolling local nodePolling remote node Polling remote node Polling remote nodePolling local nodeONON

Therefore, data can be read.If communications are performed at 9,600 bps, however, the two pollingcycles will be 131 ms, and communications will not be able to be performedwithin the two polling cycles.

60Relay Function Section 4-14-1 Relay FunctionThe relay function extends the communications distance using an I/O SlaveStation as a Relay Station. Even if equipment is relocated, making communi-cations between the Serial Master Station and I/O Slave Stations unstable orresulting 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 DistanceWhen the Serial Master Station and I/O Slave Stations are separated by along communications distance, communications with stations for which radiowaves 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 asingle 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 Stationbeing used as the Relay Station are disabled. If an I/O Slave Station is withinthe communications range for the Serial Master Station, communications withthe Serial Master Station can be performed directly even if a Relay Station isinstalled. Relays are supported for only one stage, i.e., only for one Relay Sta-tion.I/O Slave StationsWT30-M01-FLK ANT1ANT2WT30-SID16ANT1ANT2WT30-SID16ANT1ANT2WT30-SID16ANT1ANT2WT30-SID16ANT1ANT264 max.WT30-M01-FLK Serial Master StationRelay Station (I/O Slave Station)WT30-@@@

69Troubleshooting Section 5-1WS indicator Status CountermeasureLit red A fatal wireless communications error has occurred. Duplicate wireless node numbers have been detected. Another I/O Slave Station with the same fre-quency channel and node number settings may be present. Check whether an I/O Slave Station with the same frequency channel and node number settings is within the radio wave range. If an I/O Slave Station with duplicate settings is found, change the frequency channel and node number setting and then restart the system. If the system does not recover, reset the affected I/O Slave Station to a frequency without interfer-ence. Flashing red A non-fatal wireless communications error has occurred. A disconnection has occurred, a com-munications timeout, or a verification error (I/O size mismatch) has occurred.If the RSSI display is not lit, this indicates a dis-connection. Change the frequency channel and relocate the WT30 Terminal to a position in which stable wireless communications are pos-sible. If the RSSI display is lit, this indicates an I/O size mismatch error. Re-register the I/O Slave Station from the Serial Master Station.

99Appendix CI/O Response TimeI/O Response TimeCompared 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 orPLC 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) × 2T3: 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 timeTCMD: Command send timeInputOutputFor details on the command send time, refer to 3-6-4 Input Hold on page 53.Command send timeResponse receive timeWaitApprox. 50 ms max.Cycle × 2TWCY = 10 ms × n stationsPC/PLCSerial Master StationI/O Slave StationTWCY TWCYT1 T2 T3Input filter10 ms/100 msCommand send timePC/PLCSerial Master StationI/O Slave StationCycle × 2TWCY = 10 ms × n stationsTWCYTWCYTCMDTOUTT2Output delay (approx. 1 ms)
100I/O Response Time Appendix CWireless 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 theSerial 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 StationsThe 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 msExample 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 msThe calculations shown here indicate theoretical values and should be considered as a rough guide only. Theactual values obtained will depend on the installation environment.ΣWNODEΣWNODEΣWNODE
