Figure 96: Function block
Functionality
The function compares the integer inputs INT_IN1 and INT_IN2 and activates the
binary output OUTPUT, if INT_IN1 is not equal to INT_IN2.
If INT_IN1 ≠ INT_IN2, OUTPUT = 1, else OUTPUT = 0.
Logic function blocks do not have the hysteresis feature. Oscillating
outputs should be avoided when comparing analog signals that have
very closely varying values.

Configurable logic Q/T

A number of logic blocks and timers with the capability to propagate timestamp and
quality of the input signals are available. The function blocks assist the user to adapt
the IEDs configuration to the specific application needs.
