Description Note
LT: less than (I1 < I2) Less than (I1 < I2)
EQ: equal to (I1 = I2) Equal to (I1 = I2)
GT: greater than (I1 > I2) Greater than (I1 > I2)
Function block outputs
Description Note
(Bit)
Q1 Status 1 if condition is fulfilled
(e.g. I1 < I2 with LT mode active)
CY
Status 1 if the above permissible value range of the function
block is exceeded.
If an out of range
value is indicated
with CY = 1, Q1 will
remain 0.
