Since the wireless region is divided into 34 frequencies from 2,400 to 2,483.5MHz, you can sele ct an unused frequency for building multiple systems.

Using a spectral spread me thod (DS: direc t spread) as a mo dulation method achieves high-quality communications even in areas of excess noise.

Although communications distances vary according to the installation environment, the goal indoors is 60m in line of sight.

The relay functions allow an increase in the communicati ons area (to a maximum 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.

antennas). The effects of this function are observed when used in areas where variations

in radio waves (such as reflections) occur. Depending on the switch settings of the wireless master station, the maximum

number of I/O per wireless master station can be increased to 100 words/ 100 words (IN/OUT). The maximum number of wireless slave stations that can be connected has increased to 64.

Using the magnet-base antenna, the station itself can be installed inside a control panel with the antenna ins talled outside. Al so, because it is mounte d with a magnet, the p osition of the antenna can be adjusted e asily when, for example, the control panel is moved. Attenuation in the ante nna cable (2m), however, limits the maximum communic ations di stanc e to appr oximately 50m indoors.

1-2 Basic Functions of the DeviceNet Wireless Unit

1-2-1 Replacing data

Initializing the wireless master station

When the power supply is tur ned on, the wirele ss master station add s each registered wireless slave station. When wireless communicati on begins with an slave station, if the number of I/O points on the DeviceNet slave connected to the slave station and the I/O points registered for the wireless m aster station are identical, it is added. If they are not identical, an I/O configuration error will occur.

If the number of I/O points on the wireless master station and the wireless slave station is different, an I/O configuration error will occur.

Even if an error occ urs in the DeviceNet network b elow a wirele ss slave station after initialization is complete, the wireless network polling communication will continue as normal. The user should monitor the status at his device (PLC, computer) when an error occur s, and apply the appropria te error processing program for the type of error and the area in which it occurred.

Each of the following for the DeviceNet mas ter st a tus of added wireless s lave stations is set to an OR value.

Incorrect switch setting/EEPROM error (bit address 00) Repetitive node address/Busoff detection (bit address 01) Configuration error (bit address 03) Structural error (bit address 04) Send error (bit address 05) Communication error (bit address 06) Verify error (bit address 07)

Also, if a wireless slave station has been registe red but not added, the bit wi ll be 1. For example, if a wireless slave station error oc curs 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.

Basic Functions of the DeviceNet Wireless Unit Section 1-2

Refer to the "DeviceNet User’s Manual" for details concerning DeviceNet master status errors.

1-2-5 Disconnect/Connect Switch

The Disconnect/Connect Switch function that was introduced with CS/CJseries DeviceNet master uni ts c an b e us ed for wireless sl ave stations. A bit is allocated to each wirel es s sl ave station’s WNODE, and if this bit is turned ON (1), wireless I/O com municat ions and mess age communi cati ons with t he cor responding wirele ss slave station will stop (i.e., the wireless slave station is disconnected from the network). This function is mainly used to reserve space for wireless slave stations to be added in the future (i.e., I/O point s have been registered in the wireless master station but no wireless slave station has been connected yet).

Wireless slave stations tha t have been disc onnected from the net work do no t need to be considere d when calculating the wireless communic ations cycle time.

In the DeviceNet master unit’s I/O area, 0 is set in the IN area allocated to wireless slave stations that have been set to leave the network.

Basic Functions of the DeviceNet Wireless Unit Section 1-2

1-2-6 DeviceNet node addresses

DeviceNet node addresses (NNODEs) are included in wireless master stations. The master unit controls the assignment of DeviceNet slave I/O data registered with wirele ss slave stations to areas corresp onding to these node addresses.

Wireless node add resses (WNODEs) are included in wir eless slave stations. These node addresses are used for control by wireless master stations. Therefore, there is no purpose in assigning the wireless slave station DeviceNet node addresses (NNODEs) to I/O. Normally, a 7 segment LED is used to display the DeviceNet node address on wireless slave stations.

Since DeviceNet node addresses are controlled by wireless slave stations, be sure to set the DeviceNet slaves so that there is no redundancy.

The default settings ca n be retur ned to on b oth wireles s master sta tions and slave stations using the DIP switches in SET mode. Refer to 2-4 System Initial Setting and Starting Communications for detailed setting information.

1-2-8 Serial Number Check

With the release of the WD30-ME wi th Identity Ob ject Revision value 3.02, it has become possible to register the serial number (the wireless slave station’s own unique ID) of wireless slave stations to non-volatil e memory in th e wireless master station.

If a wireless slave station is registered to a wireless master station using switch operations at the wire less master sta tion, or if seri al number check is enabled for the wireless slave station by editing the device parameters using the configurator, and the seria l number is wr itten, the wi reless sl ave station’s serial number is re gistered to the wireles s master s tation’s non-volatile memory.

This function is for preventing incorrect WNODE settings for wireless slave stations, and communications errors resulting from the effects of intermodulation.

If serial number check is enabled for all the wireless sl ave stations registered to a wireless master station, the dot on the right-hand side of the wireless master station’s 7-segment LED lights.

Application Limitations Section 1-4

1-4 Application Limitations

The wireless unit is not des igned to b e com patible with every type of appl ication that uses DeviceNet. Do not use the unit with the following applications.

1,2,3... 1. Applications that require real-time control

Do not use the unit with applications th at r e qui re r eal -tim e c on tr ol. In par ticular, it cannot be used under conditions that require responsiveness greater than that outlined in "Section 9 Communications Timing".

Applications that do not require real-time control, such as indicators, equipment error monitors, and parts picking operation, are recommended.

2. Applications that use FINS message communications Wireless units do not support FINS message com munic ati on s. For exam-

ple, although CX-Programmer Ver. 2.1 and later versions suppor t online connection (i.e., remote programming and monitoring) to PLCs on DeviceNet networks (e.g., PLCs with CS/CJ-series DeviceNet Units or programmable slaves), this functionality is not available via wireless units.

1-5 Points for Consideration with Wireless Systems

1-5-1 Construction of mul t iple wireless systems

When construc ting a system for using multiple wi reless master stations, th e following points must be considered. Consult your OMRON representative.

Points for Consideration with Wireless Systems Section 1-5

Setting wireless channels It is necessar y to select frequencies for the wireless channels that are not

interfered with by radio waves. (Radio inter ference can be handled by retr y processes between the wireless networks, but will lengthen the system response time.)

With this unit, 34 wireless channels can be selected from. Taking the following points into consideration, however, the maximum number of wireless systems usable 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 the same frequency as this unit. Select an unused wireless channel using the Configurator’s wireless channel monitor function.

2. Do not select neighboring wireless channels as they have a large amount of interference.

3. 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. (This phenomenon is called “intermodulation.”)

-(f2 - f1)=1ch

Radio wave created by intermodulation

Wireless master station

Wireless slave station

f1=5ch f2=9ch

Wireless master station

Wireless slave station

f2+(f2 - f1)=13ch

Radio wave created by intermodulation

Do not select the frequencies of waves created by intermodulation.

Antenna separation distance

The distance be tween wireless unit s has a large influ ence on the amou nt of interference received. In par ticular, there may often be cases where wireless master stations are installed relatively closely to each other. Separate the antennas for different wireless master st ations by at least 1 m (at least 2 m, if possible).

Test c onfirmation Perform a test to see whether or not the wireless units are rece iving interfer-

ence. Using the Configurator’s running test function, obtain the packet error rate, and, based on this, determine whether or not the communications quality is sufficient for the appl ication. (As a r ough guide, the packet rate should b e less than 0.01.)

Intermodulation

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 diff erent frequencies, and new waves will be generated with f requencies at intervals equal to t he intervals betw een the output frequencies.

Points for Consideration with Wireless Systems Section 1-5

!Caution Communications errors caused by intermodulation

Communications errors and retry proces sing may occur due to inter modulation and consequently cause transmission delays. In order to eliminate the influence of intermodulation, do not set the wireless channels for wireless units in every system to frequencies at regular intervals.

Before starting ope ration o f th e wi r ele ss sy ste m u sing a W D30-ME with Identity Object Revision value 3.02, eithe r register wireless slave stations to the wireless master station using switch operations at the wireless master station, or enable serial number check for the wireless slave stations using the configurator, and then register the seri al numbers of the wireless slave stations to the wireless master station by writing the serial numbers.
