This value is multiplied by the gain parameter A. Parameter B (offset) is added to the
product, i.e.
(Ax ∙gain) + offset = Actual value Ax.
3.4.24 Analog value monitoring
Short description
This special function saves the process variable of an analog input to memory, and sets
the output when the output variable exceeds or drops below this stored value plus a
configurable offset.
Connection Description
Input
A positive edge (0 to 1 transition) at input En saves the
analog value at input Ax ("Aen") to memory and starts
monitoring of the analog range Aen ± Delta.
Input
You apply the analog signal to be monitored at input Ax.
Use the analog inputs AI1...AI8, the analog outputs AQ1
and AQ2.
0 - 10 V is proportional to 0 - 1000 (internal value).
Parameter
A: Gain
Range of values: ± 10.00
B: Zero offset
Range of values: ± 10,000
Delta: Difference value for the Aen on/off threshold
Range of values: ± 20,000
p: Number of decimals
Range of values: 0, 1, 2, 3
Output
Q is set/reset, depending on the stored analog value and the
offset.
Parameter p (number of decimals)
