<D4. Starting up the Field Wireless System>

D4-2

IM 01W02D01-01EN

The method of starting operation for IO devices is the same as for devices with routing functions .

Using the Monitor, conrm that all eld wireless devices have connected (Full Join) to the net-

work. Instructions on how to check this with the Monitor are described below.

After conrming that all eld wireless devices have connected (Full Join) to the network, when 3

to 6 hours have elapsed, use the Monitor to check the radio communications path, communica-

tions quality and status of the eld wireless devices. If there is any problem with communication

quality or paths, reconsider the positions of the eld wireless devices and/or antennas and adjust

them.

For details of how to check communications quality with the Monitor and use device manage-

ment functions see Section D4.2 Wireless Network Management.

IMPORTANT

Within the same eld wireless subnet, while a eld wireless device is trying to join through an

existing the Field Wireless Access Point, a new Field Wireless Access Point is not available im-

mediately. Once the eld wireless device has successfully joined, the new Field Wireless Access

Point will be available.

D4.2 Wireless Network Management

Check that the eld wireless network is up and all communications are stable, then the system

will be a normal operation.

Since the quality of wireless communications is affected by the environment of the communica-

tions paths. Even after checking that communications are stable,

Various causes (installation of structures or machines, arrival of a large vehicle, temporary con-

struction installations, or new installation of wireless networks using the same frequency on a dif-

ferent wireless LAN) may lead to deterioration. To keep a stable eld wireless network, requires

regular status monitoring and maintenance of the wireless network.

The Monitor in the Field Wireless Management Console built into YFGW410 is used for monitor-

ing status and management of the wireless network and devices.

D4.2.1 Monitor Functions

The Monitor provides functions to show the wireless network topology, backbone device status

(YFGW410 and YFGW510), and eld wireless device status, functions for logging operations

and warning or fault messages, and functions for updating the rmware of the devices .

These functions are related as follows.
