Use the analogue inputs AI1...AI8,
the analogue outputs AQ1 and
AQ2.
AI1...AI8: 0 - 10 V corresponds with
0 - 1000 (internal value).
Parameter
A: Gain
Range of values: ± 10.00
B: Zero offset
The range of values: ± 10,000
p: Number of decimals
Range of values: 0, 1, 2, 3
Output AQ
Analog output
Value range for AQ: -
32768...+32767
Parameter p (number of decimals)
Applies only to the display of Ax and Ay values in a
message text.
Does not apply to the comparison of On and Off values!
(The compare function ignores the decimal point.)
Description of function
The function reads the value of an analogue signal at the
analogue input Ax.
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.
Analogue Watchdog
Description of function
This special function saves the process variable of an
analogue 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 En ( )
A positive edge (0 to 1 transition) at
input En saves the analogue value at
input Ax ("Aen") to memory and
starts monitoring of the analogue
range Aen ± Delta.
Input Ax
You apply the analogue signal to
be monitored at input Ax.
Use the analogue inputs AI1...AI8,
the analogue 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
The range of values: ± 10,000
Delta: Difference value for the Aen
on/off threshold
The range of values: ± 20,000
