24.11 ISaGRAF Application Examples
A brief overview of some of the applications which are implemented with the help of ISaGRAF is mentioned
in the subsections below.
24.11.1 Battery Testing
This application was written to perform a Battery Voltage test, which is to be performed at the specified time
on a periodic basis. The application initiates at the specified time, activates a relay to switch to Battery mode
for a very short duration, check the voltage status and switch back to the main power supply.
24.11.2 Redundant Communication over TCP/IP
This application switches the communication from the MultiSmart from the Primary Server to the Backup
Server in case of a server failure. The Program checks if the communication channel is still alive periodically.
If a communication failure occurs, the IP address of the Primary Server to which the MultiSmart is talking will
be changed with the IP address of the Backup Server. This will enable communication from MultiSmart to the
Backup Server.
