Section 1-1 DeviceNet Wireless Unit 1-1 DeviceNet Wireless Unit The DeviceNet wireless unit, consisting of a DeviceNet wireless master station 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.
Section 1-1 DeviceNet Wireless Unit We recommend that this function be used for applications that are not required to operate in real time (such as displays for indicators and manufacturing 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.
Section 1-2 Basic Functions of the DeviceNet Wireless Unit DeviceNet wireless slave station (Wireless slave station) • As an slave station for the wireless network, it exchanges remote I/O communications 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 maximum of 64 words (1,024 points) I/O control.

Section 1-2 Basic Functions of the DeviceNet Wireless Unit 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.) 1.
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 units can be used for wireless slave stations.
Section 1-2 Basic Functions of the DeviceNet Wireless Unit 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 wireless slave stations to areas corresponding to these node addresses. Wireless node addresses (WNODEs) are included in wireless slave stations. These node addresses are used for control by wireless master stations.
Basic Functions of the DeviceNet Wireless Unit 1-2-7 Section 1-2 DeviceNet wireless unit default setting values Wireless unit network default settings are on a 1:1:2 structure of wireless master station: wireless slave station: DeviceNet slave with IN/OUT = 16 points/16 points, as shown in the figure below.

Section 1-3 Configurator Outline 1-3-3 Outline of functions • Monitor the network condition of the wireless unit • Set and reference parameters of the wireless unit (setting/referencing wireless slave entry, number of I/O points, and wireless slave station routing information) • Monitor channels (monitor the transmission levels of used frequency bands, and keep logs) • Running test (perform running tests according to user configurations without grouping PC and PLC applications, and leave a test log with
Section 1-4 Application Limitations 1-4 Application Limitations The wireless unit is not designed to be compatible with every type of application 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 that require real-time control. In particular, it cannot be used under conditions that require responsiveness greater than that outlined in "Section 9 Communications Timing".
Section 1-4 Application Limitations 3. Applications that use Peer to Peer communications between the upper DeviceNet network DeviceNet master and the lower DeviceNet net-work DeviceNet master.
Section 1-5 Points for Consideration with Wireless Systems 4. Applications that require setting the DeviceNet slave "Communication Error Output" to "Standby" When a wireless slave station is reset from some error, it is possible that the DeviceNet slave output will be momentarily cleared. Therefore, applications that set the output to "Standby" during communication errors can not be used.
Section 1-5 Points for Consideration with Wireless Systems Setting wireless channels It is necessary to select frequencies for the wireless channels that are not interfered with by radio waves. (Radio interference can be handled by retry processes between the wireless networks, but will lengthen the system response time.) With this unit, 34 wireless channels can be selected from.
Points for Consideration with Wireless Systems Section 1-5 !Caution Communications errors caused by intermodulation Communications errors and retry processing may occur due to intermodulation 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 operation of the wireless system using a WD30-ME with Identity Object Revision value 3.

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.
Deciding the Antenna Installation Position Section 2-7 The OMRON V690 microwave RF-ID system uses frequencies within the range 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 antennas Antennas emit waves in certain directions, and there are certain directions in which waves are received easily.

Section 5-1 Test 5-1 Test • The test consists of the Installation test, confirmation test and wireless channel monitor. • The positioning test must be implemented on the system that uses this unit before operation. • Temporarily fix the unit till the test is finished, and then use screws to firmly fix the unit. While the unit is fixed only temporarily, pay attention so that the unit will not fall and be damaged. • The purpose of each test is as follows.
Section 5-2 Installation Test 5-2 Installation Test This test is for adjusting the installation position (confirmation of receiving wave, etc.) and the setup conditions (selection of unused frequencies, selection of transmission output, etc.) at installation. Both master and slave stations require the switch operation. 5-2-1 Preparation • The DeviceNet master and DeviceNet slave do not need to be connected for the installation test.
Section 5-2 Installation Test If the WS LED lights green, this means that the wireless communication link has been established. Position the devices so that the WS LED lights green. If the electric wave is weak, adjust the position of the wireless slave station so that receiving wave level is stabilized in L5 or higher.
Section 5-3 Confirmation Test 5-3 Confirmation Test This test is for checking the wireless communication status with each slave station in the system in operation after installation. The test can be implemented by the switching operation from the master station. 5-3-1 Preparation • The DeviceNet master does not need to be connected for the confirmation test. (The DeviceNet slave needs to be connected.) • The confirmation test is employed for the inspection work after installation.

Section 10-3 Maintenance Error content Send error Bit address Cause Remedy 05 Network power supply error, send timeout Check the network power supply and the network cable wiring. Review the following items. • Communication speed • Cable length (main/branch) • Broken or loose cable • Terminating resistor should only be installed on both ends of the main line.
Section 10-3 Maintenance • Alcohol and all-cotton cloth Equipment that could be needed • Synchroscope • Oscilloscope (pen-writing type) • Thermometer, hygrometer Inspection item Check the items in the following table to make sure they meet the standard. If they do not, improve the surrounding environment so they meet the standard or adjust this unit.

Appendix C Current Consumption List Current Consumption List Model WD30-ME/-ME01 *1 Total current consumption Max. 350mA WD30-SE/-SE01 Max. 350mA *1 The wireless unit receives the total power supply from the communication power supply via the dedicated DeviceNet cable. Thus, the total power supply listed here does not distinguish the internal circuit area from the communication area. Taking the maximum current at startup into consideration, however, use a power supply of at least 350mA.
