Analog Differential Trigger - Easy Electronics xLogic Micro PLC User Manual

6.5.25 Analog differential trigger

Short description
The output is set and reset depending on a configurable threshold and a differential value.
Connection
Input Ax
Parameter
Output Q
Parameter p (number of decimals)
Applies only to the display of On, Off and Ax values in a message text.
Does not apply to the comparison of On and Off values! (The compare function ignores the decimal
point.)

Description
You apply the analog signal
to be analyzed 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).
A: Gain
Range of values: ± 10.00
B: Zero offset
Range of values: ± 10,000
On: On threshold
Range of values: ±20,000
Delta: Differential value for
calculating the off parameter
Range of values: ± 20,000
p: Number of decimals
Range of values: 0, 1, 2, 3
Q is set or reset, depending
on the threshold and
difference values.
