Equality check for real signals EQR

Figure 85: Function block
Functionality
The EQR function block compares the real inputs REAL_IN1 and REAL_IN2 and
activates the binary output OUTPUT, if REAL_IN1 is equal to REAL_IN2.
If REAL_IN1 == REAL_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.
