If a browser other than these browsers is used, the contents may not be
displayed properly. Use one of the supported browsers to see the contents.
If the controller is accessed from a browser while the controller internal
processing is in progress, the controller performance degrades. To prioritize
controller internal processing (writing a file or giving instruction to an air
conditioner), the system once stops the access from the browser. At this time,
the browser may fail to display buttons or other elements.
The missing GUI elements can be displayed by refreshing the browser
window.
For Internet Explorer, click [View] and then [Refresh]. For Firefox, click [View]
and then [Reload].
Connection via an intra-company LAN may slow screen display due to a busy
network, possibly causing the display failure of those elements. Use the
system during off-peak hours of network use, or use a dedicated network to
connect a PC with the controller.
If a 10 BASE switching HUB is used, replace it with a 100 BASE switching
HUB.
