• Analog output QA01

• Actual value

… QV> of another function block

Specifying the marker range without offset

If MB, MW or MD markers are specified at both >I1 and >I2 the number of

the markers is the start of comparison range 1 or 2.

Specifying the marker range with offset

If you wish to work with an offset, specify one of the following variables at

function block input

>I1 or >I2:

• Constant,

• Actual value ..QV of a function block,

• Analog input IA..,

• Analog output QA..
