Creating custom applications for computers or dedicated automation controllers that communicate with
ControlByWeb products is not a difficult task for many programmers. This can be done using most
programming languages.
All of the ControlByWeb products are similar in the way they communicate with custom applications. Code
examples in various programming languages are given in the WebRelay downloads page.
The Time Synchronization Utility is a command line utility that can be used to synchronize
the real time clock of multiple WebRelay-Dual devices to that of a computer. It requires a
computer running a Windows operating system. This utility can be scheduled to run daily in
order to keep the time of one or more WebRelay-Dual devices accurate.
