In this Function Block Diagram, the first row is to catch the rising edge of breaker 2
failure and check Reset signals.
The second and third row are to generate an On/Off square wave (Tripping signal) from
a break failure status by using Timer Pulse, Timer and XOR gate function blocks.
The last row is to send generated Tripping signal to open the breakers. A Timer Delay
is added between the Select Off and Operator outputs to make sure it is a Select/Operate
operation.
When it receives a Reset signal, the logic sets all signals to Off and stops sending trip
signal to IEDs.
