2DeviceNet Wireless Unit Section 1-11-1 DeviceNet Wireless UnitThe DeviceNet wireless unit, consisting of a DeviceNet wireless master sta-tion and a DeviceNet wireless slave station, allows wireless communicationwith the DeviceNet slave.Basically, the wireless master station is connected to the DeviceNet networkand acts as either a virtual DeviceNet slave or wireless network master stationfor the DeviceNet master unit. The wireless slave station acts as either a wire-less network slave station or a virtual DeviceNet master with the DeviceNetslave unit.This unit conforms to the following radio wave standards.Conformance with these standards means that the antenna can be installedseparately. The unit can be purchased as a set with a pencil antenna (WD30-ME/-SE) or with a magnet-base antenna (WD30-ME01/-SE01). (The dia-grams in this manual are for the WD30-ME/-SE.)1-1-1 System configuration1-1-2 FeaturesDeviceNet slaves can be made wireless Wireless DeviceNet slaves allows for a variety of field level applications.

3DeviceNet Wireless Unit Section 1-1We recommend that this function be used for applications that are notrequired to operate in real time (such as displays for indicators and manufac-turing instruction data transmissions).Errors can be monitored DeviceNet slave error information (including errors in wireless slave stations)can be assigned to two or four status words and monitored from the PLC.Abundant number of wireless channels allows the construction of multiple systems in the same areaSince the wireless region is divided into 34 frequencies from 2,400 to2,483.5MHz, you can select an unused frequency for building multiple sys-tems.Using a spectral spread method (DS: direct spread) as a modulation methodachieves high-quality communications even in areas of excess noise.Relay functions make possible an extension in communications distancesAlthough communications distances vary according to the installation environ-ment, the goal indoors is 60m in line of sight.The relay functions allow an increase in the communications area (to a maxi-mum of 3 stages).DeviceNet slaves may also be connected to the relay station.However, relay station system settings can only be performed from the config-urator.Diversity functions Multi-pass phasing is improved with a diversity system (which requires 2antennas).The effects of this function are observed when used in areas where variationsin radio waves (such as reflections) occur.Maximum number of I/O per wireless master station increasedDepending on the switch settings of the wireless master station, the maximumnumber of I/O per wireless master station can be increased to 100 words/100 words (IN/OUT). The maximum number of wireless slave stations thatcan be connected has increased to 64.Magnet-base antenna added to lineup Using the magnet-base antenna, the station itself can be installed inside acontrol panel with the antenna installed outside. Also, because it is mountedwith a magnet, the position of the antenna can be adjusted easily when, forexample, the control panel is moved. Attenuation in the antenna cable (2m),however, limits the maximum communications distance to approximately 50mindoors.1-1-3 Types of unitsDeviceNet wireless master station (Wireless master station)• Connects to the DeviceNet network and acts as a virtual DeviceNet slave.• Maximum number of I/O as DeviceNet slave: IN/OUT = 32 words (512points)/32 words (512 points) or 100 words (1,600 points)/100 words(1,600 points) depending on the DIP switch setting.

For example, if a wireless slave station error occurs for WNODE = 16,the uppermost bit for "status begin word +0" (16) becomes 1.Each wireless master station can control a maximum of 512 (or 1,600) I/O points. However, there are limits to the number of I/O points per node for each master unit. Therefore, systems should be designed without exceeding the limitations for the number of I/O points per node for each master unit.Master unit I/O point limitations15 187 0Status begins Wd+0Wd+1 Slave error flagWd+1Wd+2Wd+315 187 0Status begins Wd+0Slave error flag15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 1715 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 1748 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49
9Basic Functions of the DeviceNet Wireless Unit Section 1-2Refer to the "DeviceNet User’s Manual" for details concerning DeviceNetmaster status errors.1-2-5 Disconnect/Connect SwitchThe Disconnect/Connect Switch function that was introduced with CS/CJ-series DeviceNet master units can be used for wireless slave stations. A bit isallocated to each wireless slave station’s WNODE, and if this bit is turned ON(1), wireless I/O communications and message communications with the cor-responding wireless slave station will stop (i.e., the wireless slave station isdisconnected from the network). This function is mainly used to reserve spacefor wireless slave stations to be added in the future (i.e., I/O points have beenregistered in the wireless master station but no wireless slave station hasbeen connected yet).Wireless slave stations that have been disconnected from the network do notneed to be considered when calculating the wireless communications cycletime.In the DeviceNet master unit’s I/O area, 0 is set in the IN area allocated towireless slave stations that have been set to leave the network.
10Basic Functions of the DeviceNet Wireless Unit Section 1-21-2-6 DeviceNet node addressesDeviceNet node addresses (NNODEs) are included in wireless master sta-tions. The master unit controls the assignment of DeviceNet slave I/O dataregistered with wireless slave stations to areas corresponding to these nodeaddresses.Wireless node addresses (WNODEs) are included in wireless slave stations.These node addresses are used for control by wireless master stations.Therefore, there is no purpose in assigning the wireless slave stationDeviceNet node addresses (NNODEs) to I/O. Normally, a 7 segment LED isused to display the DeviceNet node address on wireless slave stations.Since DeviceNet node addresses are controlled by wireless slave stations, besure to set the DeviceNet slaves so that there is no redundancy.DeviceNet master unitDeviceNet networkWireless networkDeviceNet slaves DeviceNet slavesDeviceNet slavesWireless master stationWireless slave stationWireless slavestationThere should be no redundancy within this area.There should be no redundancy within this area.Redundancy is acceptable in this area.

Refer to 2-4 System InitialSetting and Starting Communications for detailed setting information.1-2-8 Serial Number CheckWith the release of the WD30-ME with Identity Object Revision value 3.02, ithas become possible to register the serial number (the wireless slave station’sown unique ID) of wireless slave stations to non-volatile memory in the wire-less master station.If a wireless slave station is registered to a wireless master station usingswitch operations at the wireless master station, or if serial number check isenabled for the wireless slave station by editing the device parameters usingthe configurator, and the serial number is written, the wireless slave station’sserial number is registered to the wireless master station’s non-volatile mem-ory.This function is for preventing incorrect WNODE settings for wireless slavestations, and communications errors resulting from the effects of intermodula-tion.If serial number check is enabled for all the wireless slave stations registeredto a wireless master station, the dot on the right-hand side of the wirelessmaster station’s 7-segment LED lights.Wireless master stationI/O points: IN 1 word (16 points) OUT 1 word (16 points)Registered wireless slave station: 1 nodeWireless slave stationWNODE=01IN/OUT=1 word (16 points) 1 word (16 points)DeviceNet slaveNNODE=01IN/OUT=(16 points/0 point)DeviceNet slaveNNODE=02IN/OUT=(0 point/16 points)

14Application Limitations Section 1-41-4 Application LimitationsThe wireless unit is not designed to be compatible with every type of applica-tion that uses DeviceNet. Do not use the unit with the following applications.1,2,3... 1. Applications that require real-time controlDo not use the unit with applications that require real-time control. In par-ticular, it cannot be used under conditions that require responsivenessgreater than that outlined in "Section 9 Communications Timing".Applications that do not require real-time control, such as indicators, equip-ment error monitors, and parts picking operation, are recommended.2. Applications that use FINS message communicationsWireless units do not support FINS message communications. For exam-ple, although CX-Programmer Ver. 2.1 and later versions support onlineconnection (i.e., remote programming and monitoring) to PLCs on De-viceNet networks (e.g., PLCs with CS/CJ-series DeviceNet Units or pro-grammable slaves), this functionality is not available via wireless units.CX-Programmer installed on a computerWireless master stationWireless slave stationLower DeviceNet networkProgrammable slaveUpper DeviceNet networkCS1

16Points for Consideration with Wireless Systems Section 1-54. Applications that require setting the DeviceNet slave "CommunicationError Output" to "Standby" When a wireless slave station is reset from some error, it is possible thatthe DeviceNet slave output will be momentarily cleared. Therefore, appli-cations that set the output to "Standby" during communication errors cannot be used.5. Applications where software reset (Explicit messages) must be performedfor the slave station from the upper DeviceNet network1-5 Points for Consideration with Wireless Systems1-5-1 Construction of multiple wireless systemsWhen constructing a system for using multiple wireless master stations, thefollowing points must be considered. Consult your OMRON representative.DeviceNet slavesOUTDeviceNet master unitUpper DeviceNet networkWireless networkLower DeviceNet networkWireless master stationWireless slave stationOutput set to "Standby" during transmission errorsCleared momentarily
17Points for Consideration with Wireless Systems Section 1-5Setting wireless channels It is necessary to select frequencies for the wireless channels that are notinterfered with by radio waves. (Radio interference can be handled by retryprocesses between the wireless networks, but will lengthen the systemresponse time.)With this unit, 34 wireless channels can be selected from. Taking the followingpoints into consideration, however, the maximum number of wireless systemsusable in a single area without radio interference is, as a rough guide, 10.1. It is possible that, for example, there is a wireless LAN on site that uses thesame frequency as this unit. Select an unused wireless channel using theConfigurator’s wireless channel monitor function.2. Do not select neighboring wireless channels as they have a large amountof interference.3. Due to the fundamental nature of radio waves, if 2 or more waves with dif-ferent frequencies are output at exactly the same time, mutual interferencewill occur between the different frequencies, and new waves will be gener-ated with frequencies at intervals equal to the intervals between the outputfrequencies. (This phenomenon is called “intermodulation.”)Do not select the frequencies of waves created by intermodulation.Antenna separation distance The distance between wireless units has a large influence on the amount ofinterference received. In particular, there may often be cases where wirelessmaster stations are installed relatively closely to each other. Separate theantennas for different wireless master stations by at least 1 m (at least 2 m, ifpossible).Test confirmation Perform a test to see whether or not the wireless units are receiving interfer-ence. Using the Configurator’s running test function, obtain the packet errorrate, and, based on this, determine whether or not the communications qualityis sufficient for the application. (As a rough guide, the packet rate should beless than 0.01.)Due to the fundamental nature of radio waves, if 2 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.Intermodulationf1=5ch f2=9chf1-(f2 - f1)=1ch f2+(f2 - f1)=13chWireless master station Wireless master stationWireless slave station Wireless slave stationRadio wave created by intermodulation Radio wave created by intermodulation
18Points for Consideration with Wireless Systems Section 1-5!Caution Communications errors caused by intermodulationCommunications errors and retry processing may occur due to intermodula-tion and consequently cause transmission delays. In order to eliminate theinfluence of intermodulation, do not set the wireless channels for wirelessunits in every system to frequencies at regular intervals.Before starting operation of the wireless system using a WD30-ME with Iden-tity Object Revision value 3.02, either register wireless slave stations to thewireless master station using switch operations at the wireless master station,or enable serial number check for the wireless slave stations using the config-urator, and then register the serial numbers of the wireless slave stations tothe wireless master station by writing the serial numbers.

22Pre-work Preparations Section 2-22-2 Pre-work PreparationsItems to be checked before performing installation work are explainedhere.2-2-1 Determination of system configurationA single wireless master station is limited to a maximum of 1,024 or 3,200points, 512 (32 words) or 1,600 (100 words) points each for both IN and OUT.In addition, the maximum configuration in a wireless network of master sta-tions to slave stations is 1 to 32 or 1 to 64, and the maximum number of IN/OUT points for the entire system is limited by the DeviceNet master unit. Thisshould be considered carefully when determining system configuration.System configuration example In this section, the operation procedure is explained using the following sys-tem configuration as an example.A communications power supply (Model S82K) has been purposely left outof the diagram above. It should be connected and supply power to theDeviceNet network (both upper and lower) and should be connected with ter-minating resistor. In addition, an external power supply should be connectedto the environment-resistant terminal of the DeviceNet slave.2-2-2 Confirmation of specificationsConfirmation of number of IN/OUT points Confirm that the number of IN/OUT points for each wireless master station isno more than 512 or 1,600 (32 or 100 words).In the example, the number of IN points is 8 × 4 = 32, and the number of OUTpoints is 8 × 2 = 16.A single wireless master station can control up to 512 points (or 1,600 points) for both input and output, but the number of I/O points per node is limited by the master unit. Be careful not to exceed the limit for I/O points per master unit node when constructing your system.Master unit I/O limitationsDeviceNet networkDRT1-ID08CNNODE=2DeviceNet master unitModel CS1W-DRM21(NNODE=10)Wireless networkWireless mater station(NNODE=00)Wireless slave station(WNODE=01)(NNODE=00)Wireless slave station(WNODE=02)(NNODE=00)DeviceNet slavesModel DRT1-ID08C(NNODE=01)DeviceNet slavesModel DRT1-ID08C(NNODE=02)DeviceNet slavesModel DRT1-MD16C(NNODE=04)DeviceNet slavesModel DRT1-MD16C(NNODE=03)NNODE: DeviceNet node addressWNODE: Wireless node addressModelDRT-ID08C: 8 environment-resistant terminal inputsModelDRT1-MD16C: 16 environment-resistant terminal inputs/outputs
23Pre-work Preparations Section 2-2Confirmation of wiring A special communications cable is required to connect to the DeviceNetmicro-connector on the wireless unit.In addition, if multiple DeviceNet slaves are connected, branch taps should beused as necessary. Terminators for the wireless slave station DeviceNet net-work should also be prepared. Refer to the "DeviceNet User’s Manual" fordetails.Confirmation of communications power supplySince power is supplied to the wireless unit from an external communicationspower supply, a communications power connection must be made.Taking the maximum current at startup into consideration, use a power supplyof at least 350mA. If using an OMRON S82K or S82J switching power supply,use a model with a capacity of at least 30W (S82K) or 25W (S82J).2-2-3 Temporary installation and installation testTemporary installation of wireless master station Set the switches as shown below, and temporarily fix the master station in thedetermined location.Connect a DeviceNet cable prepared for a micro-connector, and connect theDC24V communications power supply.Temporary installation of wireless slave station Set the switches as shown below, and temporarily fix the master station in thedetermined location.Connect a DeviceNet cable prepared for a micro-connector, and connect theDC24V communications power supply.Performing the installation test Perform the positioning test.

If all MS and NS LEDs light greenand the node address is shown inthe LED display, the system is inRUN operation status.2-7 Deciding the Antenna Installation PositionThis unit uses radio waves of frequency 2.4GHz, which is very high. High-fre-quency waves exhibit strong rectilinear propagation and are reflected easily.For this reason, careful consideration of the antenna installation position isrequired to achieve sufficient wireless performance.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 50m or60m.)If 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 willW NODE01234567890123456789X10X1W CH01234567890123456789X10 X112345678ONSW3SW2SETTESTRUNSlave stationMS NS WSN NODE01234567890123456789X10 X11234ONSW1 SETTESTRUNSW2Slave stationTransmission antenna Obstacle Antenna that is difficult for the waves to reachArea not in a direct line of sight from the antenna Antenna that waves will reach
39Deciding the Antenna Installation Position Section 2-7propagate 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 largest influence asthey reflect radio waves, whereas glass and plastic objects allow the wavesto pass through and so have the smallest influence. Ensure a distance ofat least 30cm between obstacles and antennas.4. Cable loss in magnet-base antennasWith magnet-base antennas (WD30-ME01/-SE01), there is loss in the 2mantenna cable. This means that the maximum communications distance isshorter than with the pencil antennas. As a rough guide, the maximumcommunications distance is approximately 50m indoors.5. Cable bending radius for magnet-base antennasThe minimum bending radius for magnet-base antennas (WD30-ME01/-SE01) is 38mm. Also, do not bend the cable at points less than 40mmfrom the end connected to the station or at points less than 20mm from theend 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 eachother and thereby influence wireless communications, causing an increasein the number of retries and a reduction in the possible communicationsdistance. Separate different sets of antennas by at least 1m (at least 2m ifpossible).7. Do not install the 2 magnet-base antennas close to each other.If the 2 antennas are close to each other, the diversity effect will not be uti-lized. Separate the antennas by at least 62mm (as with pencil antennas).Magnet-mounting allows the positions to be adjusted easily. If possible,separate the antennas by a greater distance than this.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. If they are installed at an angleof 90° to each other, the possible communications distance will be short-ened. (In this case, the waves are said to be “polarized.”)9. Separate the antennas from ID tags by at least 3m.High antennaRadio wave energyObstacle
40Deciding the Antenna Installation Position Section 2-7The OMRON V690 microwave RF-ID system uses frequencies within therange used by the wireless unit and so if they are used on the same floor,observe the following points when installing.• Separate the antennas and ID tags by at least 3m.• Set frequencies outside the range 12CH to 30CH.10. Direction of waves emitted from the 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.11. Other points about magnet-base antennas• The magnet on the magnet-base antenna is very strong. Do not removethe antenna by pulling on the cover or cable. Doing so may damage theantenna. Be sure to hold the base when handling the antenna.• Twist the cable as little as possible.• Before mounting the antenna to the wireless unit, check that the plugand jack are properly connected and then tighten them by twisting thering nut. When mounting, twist only the ring nut; do not twist the cable.• Design the hole for passing the cable through so that the cable is pro-tected.

80Relay Function Section 6-16-1 Relay FunctionA wireless slave station can be used as a relay station when expansion of thecommunication area is intended but the direct communication is blocked byobstacles.The relay station can select either (1) the mode that does not connect theDeviceNet slave (dedicated relay station mode) or (2) the mode functions asboth the DeviceNet master and the relay station by connecting the DeviceNetslave (non-dedicated mode) using DIP switches. For details, refer to 4-2 DeviceNet Wireless Slave Station Specifications. The maximum number of relay stages is 3 (no. of hops: 4). A configurator is used for the relay station system setting. When the wirelessslave station is used in the dedicated relay station mode, the DeviceNet slaveis not connected. However, since the communication power supply isrequired, the communication cable needs to be connected. Also, in the relay station system, the WCH switches of all wireless units mustbe set to an identical frequency.The I/O connected with wireless slave stations are loaded first by ascendingorder of DeviceNet node addresses in the wireless slave station, and then byascending order of wireless node addresses for the slave station (WNODE) inthe wireless master station.ConfiguratorDeviceNet slavesDeviceNet slavesDeviceNet master unitDeviceNet networkWireless master stationWireless slave station (dedicated for relay station)Wireless slave station (dedicated for relay station)Wireless slave station Wireless slave station Max. of 3 relay stages (no. of hops:4)

126Remote I/O Communications Performances Section 9-19-1 Remote I/O Communications PerformancesThis section describes the performances of remote I/O communications whenthe DeviceNet wireless unit is used. Specifying communications timing as cal-culated is difficult in a wireless network compared to a wire communicationnetwork. Thus, the timings presented here are in accordance with the stan-dard expressions and the actually measured data resulting from the OMRONsystem test. This unit is not applicable for applications requiring real time con-trol. Instead, use this data as a scale to determine if this unit is applicable toyour need.The equations provided here are valid under the following conditions:• The DeviceNet Master Unit is an OMRON product.• The Master Unit is operating with the scan list valid mode.• All of the required wireless slave stations and DeviceNet slaves havebeen added in communications.• No errors are being indicated at either the DeviceNet master unit or wire-less units.• Messages are not being produced in the Network (from another com-pany's configurator, for example).Note 1. The values provided by these calculations may not be accurate if anothercompany’s DeviceNet Master or Slave unit is being used.2. This manual only refers to parts related to the wireless unit. For detailsabout the DeviceNet Master unit or the entire DeviceNet system, refer tothe "DeviceNet User’s Manual", and for details about Slaves, refer to the"DeviceNet Slave Manual".9-1-1 I/O response timeThe I/O response time is the time it takes from the reception of an input signalat an Input Slave (REMOTE I/O TERMINAL) to the output of the correspond-ing output signal at an Output Slave (REMOTE I/O TERMINAL) via the pro-cess by the ladder program in the PLC module.Since the wireless master station operates as a DeviceNet slave virtually, andthe wireless slave station operates as the DeviceNet master, also virtually, atime delay among wireless network is not noticeable in the operation from thePLC. However, the actual I/O response time depends on the number of wire-less slave stations, and if relayed, on the number of relay stages due to thetime delay among wireless networks and 1:N polling communication.The following describes the maximum I/O response time.

128Remote I/O Communications Performances Section 9-1Note For details on the Input I/O Unit input delay time and the Output I/O Unit out-put delay time, refer to the information in the "DeviceNet Slave Manual"; fordetails on the communication cycle and refresh processing time, refer to theinformation of the remote I/O communication performance in the "DeviceNetUser’s Manual". Refer to the PLC Operation Manual for details on the PLCcycle time.The maximum I/O response time (T MAX) can be obtained from the followingexpression:TMAX = TIN +TOUT +4 × TRM +2 × TWCY +2 × TPLC +TRF9-1-2 Wireless communication cycle time (TWCY)Wireless communication delay time occurs in a wireless network when usingwireless units. The wireless communication delay time becomes longerdepending on the increase in the number of wireless slave stations and relaystages. The unit is ms.Wireless slave stations for which the Disconnect/Connect Switch is set toON (i.e., disconnected) are not included in the total cycle time of wirelessslave stations.9-1-3 Actually measured reference dataUse the following values of the I/O response time (IN input -PLC processing -OUT output) measured by the OMRON system test as reference.The data described is the smallest and largest values resulting from 30 timesof continuous testing. The actual measurements could be longer than thelargest value depending on the environment where the measurements weretaken. Thus, use the results only as a reference.TWCY =Σ (Total cycle time of wireless slave stations)WNODEWNODECommand headerResponse header =Σ [{(TX_LEN<WNODE>+RX_LEN<WNODE>)/12+2+2} (No. of relay stages+1)]Command send overheadResponse send overheadTX_LEN<WNODE>=29+OUTSIZE [byte] + No. of relay stages(No. of stages = byte)RX_LEN<WNODE>: Response data lengthTX_LEN<WNODE>: Command data lengthRX_LEN<WNODE>=41+INSIZE [byte] + No. of relay stages (No. of stages = byte)OUTSIZE [byte]: Add 1, if an odd number results when even numbers, slave 8-point output, etc. are used.INSIZE [byte]: Add 1, if an odd number results when even numbers, slave 8-point input, etc. are used.

134Message Communication Performance Section 9-29-2 Message Communication Performance9-2-1 Message communication timeWhen issuing a message on the DeviceNet network from one node to another(data and CMND for SEND/RECV commands, FINS command for IOWRcommands), the time from the start of the departure of the message from theDeviceNet master on the network until the end of the departure of the mes-sage is called the "message communication time". This is defined as the timerequired for the message to reach the DeviceNet slave.If a DeviceNet wireless unit is used, since the wireless master station workstemporarily as the DeviceNet slave and the wireless slave unit works tempo-rarily as the DeviceNet master, this will be the total of the following 3 times.• "Message communication time" from the DeviceNet master to the wire-less master station• "Message communication delay time" from the wireless slave station tothe DeviceNet slave• "Wireless communication extension time" within the wireless networkHowever, regarding the actual message transmission time, since somelatency may occur within the wireless network and 1:N polling is performed,when there are several wireless slave stations or a relay, there are relaystages. Actual data is provided on the following page as a reference. Althoughthis can not be used with applications that require real time control, youshould determine whether or not this data can be used as a reference.Note Refer to the message communication capacity explanations in the DeviceNetSlave Manual and the DeviceNet User’s Manual regarding message commu-nication times on the DeviceNet network.DeviceNet master unitDeviceNet networkMessage communicationWireless master station (virtual slave)1:N polling communicationDeviceNet slaves (DRT1-232C, etc.)Wireless slave station (virtual master)Message communicationWireless slave station (relay station)
