• Signal group ( Vol. 1, 10.17 of the Manual)
• Discrepancy value
- If you have selected the ”Absolute” discrepancy criterion, enter the discrepancy value as a
number up to 2048 units. The system responds with a discrepancy error if the deviation
configured here is exceeded.
- If you have selected the ”Relative” discrepancy criterion, enter the maximum permissible
relative deviation (in %) as a decimal number. The system responds with a discrepancy
error if the percentage deviation configured here
and
the ”minimum AI deviation”
configured when ”assigning the operating system parameters” are exceeded.
The relative deviation always refers to the value which you have selected for standard value
generation according to the regulations. You can refer the relative deviation to the minimum, the
mean or the maximum of the values read into subunits A and B.
The following relationships exist between the three types of relative deviation:
(the equations apply to A > B)
The following applies to relative deviation referred to the maximum value:
r
max. value
=
A - B
A
The following applies to relative deviation referred to the minimum value:
r
min. value
=
A - B
B
The following applies to relative deviation referred to the mean value:
r
mean value
=
A - B
(A+B)
