Figure B1-2 Field Wireless Network System Example
To facilitate the understanding of the basic construction procedure of a field wireless network,
the following describes the procedure to construct a system configured as shown in Figure B1-2,
which transmits process data (PV values) measured by the field wireless device to YFGW710 at
a period of 10 seconds.
The field wireless device has a function to receive and transfer communication frames of other
field wireless devices (Routing function) and a function to send process data measured by itself
(IO function).
A field wireless device that has both functions is called a Router + IO device, and a device that
has only the IO function is called an IO device. A device that has only a Routing function is called
a Routing device.
In this system, a field wireless device is used as the IO device.
PC1 in Figure B1-2 has Field Wireless Configurator for setting and maintaining the field wireless
network and Field Wireless Management Tool for managing the field wireless network and field
wireless device as well as checking the operation conditions installed.
PC2 has FieldMate that performs provisioning of the field wireless device and FieldMate Pro-
visioning Device Tool that works in conjunction with FieldMate installed. The setting of the field
wireless device to allow it to join the field wireless network is performed from the PCs via an
infrared adapter.
Note: FieldMate R2.03.00 or later allows you to use infrared communications to set device information.
For details, refer to “I-7 Obtaining ISA100 device information” in the instruction manual (IM 01R01A01-01E) supplied with Field-
Mate.
