n Types of Device Role
As described previously, there are the following types of field wireless devices.
i. Field wireless device that only supports the routing function
ii. Field wireless device that only supports the IO function
iii. Field wireless device that supports both the routing and IO functions and is able to run either
one or both roles at the same time
The following describes the task of performing engineering of the device role of a field wireless
device in the category of iii.
TIP
A field wireless device that supports only the routing function is not available at the moment. Accordingly, when
using the routing function, it is necessary to use a field wireless device in the category of iii. Yokogawa’s EJX and
YTA are field wireless devices in the category of iii.
n Procedure to Set Device Role
The setting of the device role of a field wireless device should be performed following the steps
below.
1. Determine the device role of the field wireless device.
2. Select a device role for the device in “Device Role” in the [Edit Device] window of the Field
Wireless Configurator according to the instructions in “■ Defining Device Role” of “User Ap-
plication Engineering” in Section B1.2.2.5 of this document.
3. Download the information to YFGW710 and the wireless field device from the Field Wireless
Configurator. During the download the field wireless device will restart and temporarily leave
the field wireless network.
4. When the download is completed, start the Field Wireless Management Tool and open the
[Devices] tab page.
5. Wait a couple of minutes, and then confirm in the [Devices] tab page in Field Wireless Man-
agement Tool that the field wireless device has joined the field wireless network and that it
has the specified device role.
IMPORTANT
When using the routing function of a field wireless device, the network topology must be a mesh
network. When the network topology is a star network, the routing function cannot be used even
when this procedure is performed.
To change the network topology, YFGW710 must be restarted. For details on changing the mesh
network, refer to section B1.2.2.5, and for details on “Downloading to YFGW710”, refer to section
B1.2.4.2.
