6. Function blocks
6.1 Manufacturer function blocks
Operating ranges
l
X > XH
Q1 switches one to X < ( XH – H1)
l
X < –XH
Q2 switches one to X > -XH + H2
If the switching conditions for Q1 and Q2 are not met, both outputs will be switched off
to 0.
Only Q1, or Q1, or neither one can be switched on at any one
time.
The function block and its parameters

(DWord)
I1
Setpoint
-32768…+32767
I2
Actual value
-32768…+32767
H1
Hysteresis value 1
0…32767
H2

0…65535
In 0.1 ms; value of 10 = 1 s. If the value =
0, the function block will go through every
cycle.
