This logic group can be used to recognise the tendencies of e.g. a measured value at a glance.

This determines the tendency to the previous telegram value received and outputs the result in three different ways.

Issue:
a) as colour (green, red and orange)
(b) as a number (0, 1 and 2)
c) as text (positive, negative and neutral)

For the numerical
output, the following values apply:
0 - negative trend. Red
1 - positive trend. Green
2 - constant trend. Orange
