product, i.e.
(Ax ∙ gain) + offset = actual value of Ax.
Output Q is set or reset, depending on the set (On) threshold and difference value (Delta). The function
automatically calculates the Off parameter: Off = On + Delta, whereby Delta may be positive or negative.
See the calculation rule below.
Calculation rule
When you set a negative differential value Delta, the On threshold >= Off threshold, and:
Q = 1, if the actual value Ax > On
Q = 0, if the actual value Ax ≤ Off.
See the timing diagram A.
When you set a positive differential value Delta, the On threshold < the Off threshold, and Q = 1, if:
On ≤ the actual value Ax < Off.
See the timing diagram B.
5.5.26 Analog multiplexer
Fashion: Classic:
Short Description
This special function displays 0 or one of 4 saved analog values on the analog output.
1 on input En (Enable)
switches, dependent on S1
and S2, a parameterized
analog value to the output
AQ.
0 on input EN switches 0 to
the output AQ.
S1 and S2 (selectors) for
selecting the analog value to
be issued.
S1 = 0 and S2 = 0: The value
1 is issued
S1 = 0 and S2 = 1: The value
2 is issued
S1 = 1 and S2 = 0: The value
3 is issued
S1 = 1 and S2 = 1: The value
4 is issued
