Functionality

The real greater than or equal comparator function GER compares the real input
REAL_IN1 with the real input REAL_IN2 and activates the binary output OUT if
REAL_IN1 is equal to or greater than REAL_IN2 - TOLR or greater than input
REAL_IN2. That is, if REAL_IN1≥ (REAL_IN2 - TOLR) or REAL_IN1 >
(REAL_IN2), OUT = 1, else OUT = 0.
If input REAL_IN1 or REAL_IN2 is outside the range, then OUT is set to 0.

Figure 158: Region of GER comparison
GER function blocks do not have the hysteresis feature. Oscillating
outputs should be avoided when comparing analog signals that have
closely varying values.
