DeviceNet Wireless Unit Section 1-1
1-1 DeviceNet Wireless Unit
The DeviceNet wireless unit, consisting of a DeviceNet wireless master sta-
tion and a DeviceNet wireless slave station, allows wireless communication
with the DeviceNet slave.
Basically, the wireless master station is connected to the DeviceNet network
and acts as either a virtual DeviceNet slave or wireless network master station
for the DeviceNet master unit. The wireless slave station acts as either a wire-
less network slave station or a virtual DeviceNet master with the DeviceNet
slave unit.
This unit conforms to the following radio wave standards.
Conformance with these standards means that the antenna can be installed
separately. 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.)

We recommend that this function be used for applications that are not
required 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 area
Since the wireless region is divided into 34 frequencies from 2,400 to
2,483.5MHz, you can select an unused frequency for building multiple sys-
tems.
Using a spectral spread method (DS: direct spread) as a modulation method
achieves high-quality communications even in areas of excess noise.
Relay functions make
possible an extension in
communications
distances
Although 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 2
antennas).
The effects of this function are observed when used in areas where variations
in radio waves (such as reflections) occur.
Maximum number of I/O
per wireless master
station increased
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.
Magnet-base antenna
added to lineup Using the magnet-base antenna, the station itself can be installed inside a
control panel with the antenna installed outside. Also, because it is mounted
with a magnet, the position of the antenna can be adjusted easily when, for
example, the control panel is moved. Attenuation in the antenna cable (2m),
however, limits the maximum communications distance to approximately 50m
indoors.
1-1-3 Types of units
DeviceNetwirelessmaster
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 (512
points)/32 words (512 points) or 100 words (1,600 points)/100 words
(1,600 points) depending on the DIP switch setting. However, if Status is
selected, IN/OUT = 30 words (480 points)/32 words (512 points) or
96 words (1,536 points)/100 words (1,600 points) depending on the DIP
switch setting.
• As the wireless network master station, it controls a maximum of 64 wire-
less slave stations and sends remote I/O transmissions.
• The wireless master station was tested at the test laboratories of a third
part organization authorized by the ODVA. It is authorized as being in
conforming to ODVA conformance software.
Multi-pass phasing is the phenomenon of a radio wave being transmitted form a single point,
passing through multiple propagation paths, and then arriving at a single point.

DeviceNet wireless slave
station (Wireless slave
station)
• As an slave station for the wireless network, it exchanges remote I/O com-
munications with the wireless master station via the wireless line.
• Acts as a virtual DeviceNet master with DeviceNet slaves.
• Connects with a maximum of 63 DeviceNet slaves and performs a maxi-
mum of 64 words (1,024 points) I/O control. (Even if multiple wireless
slave stations are used, the maximum number of nodes for DeviceNet
slaves is 63.)

1-2 Basic Functions of the DeviceNet Wireless Unit
1-2-1 Replacing data
Initializing the wireless
master station When the power supply is turned on, the wireless master station adds each
registered wireless slave station. When wireless communication 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 master sta-
tion are identical, it is added. If they are not identical, an I/O configuration
error will occur.

Processing when an error
occurs Even if an error occurs in the DeviceNet network below a wireless slave sta-
tion 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 occurs, and apply the appropriate error pro-
cessing program for the type of error and the area in which it occurred.

1-2-2 I/O allocation
I/O for DeviceNet slaves is allocated in the wireless slave stations by ascend-
ing order of DeviceNet node address without leaving any unused areas, and
then in the wireless master station by ascending order of slave station wire-
less node address (WNODE) without leaving any unused areas.
• The IN and OUT areas are allocated in units of 16 points (1 word). In the
case of 8-point units, the lower byte (bits 0 to 7) is allocated and the upper
byte (bits 8 to 15) is set to 00 Hex.
• The following four types of I/O allocations can be set using the DIP switch.
1,2,3... 1. Status 2 words (32 points), I/O IN/OUT = 30 words (480 points)/32 words
(512 points)

1-2-3 DeviceNet wireless unit status
The format for the IN area status area is shown below.
Confirm this status at the CPU unit, and prepare an error processing program
for sending commands to (Explicit messages) and obtaining detailed status
reports (wireless network status, DeviceNet master status) from wireless
master stations showing error flags. (Refer to SECTION 3 Sample Program.)

2. When maximum number of I/O = 100 words/100 words:
1-2-4 Slave error flag
1. When maximum number of I/O = 32 words/32 words:
2. When maximum number of I/O = 100 words/100 words:
Each of the following for the DeviceNet master status of added wireless slave
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 registered but not added, the bit will
be 1. 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.
