B1.3.2 Network Construction Task
This section describes an overview of the construction task of a field wireless network.
▪ Setting Routing Function
▪ Time Synchronization (Connection with an NTP Server)
B1.3.2.1 Setting Device Role
The following describes the procedure to change the device role of a field wireless device de-
scribed in “Device Role” of “User Application Engineering” in section B1.2.2.5 of this document in
order to improve the wireless communication environment.
n Routing Device and IO Device
A field wireless device with a routing function is called a routing device. On the other hand, a field
wireless device with an IO function, such as a transmitter, is called an IO device.
When the radio conditions are unstable between YFGW710 and the IO device, or when a radio
signal cannot be received due to long distance transmission or due to the presence of an obsta-
cle, it is necessary to install a routing device between YFGW710 and the IO device in order to
improve the radio conditions.
Accordingly, after the operation has started, there may arise the need to add or change the
device role of the field wireless device while it is being installed in the field in order to improve the
wireless communication environment in the field.
