Time Source
Setting the time source that YFGW410 uses. Time Source is the time standard to notify the host
system from the Field Wireless Management Console and YFGW410.
To synchronize the time of the YFGW410 and host system, acquire the time from a network time
protocol (NTP) server that the host system uses. By synchronizing the time with the host system,
you can handle data with time stamps.
Even if an NTP server is not used, the Field Wireless Network operates normally based on the
time maintained by the YFGW410.
When [Time Source] is selected in the menu tree of the Configurator, the tab shown in Figure D3-
11 appears in the main window.
