The function block inputs >I1, >I2 and >NO can have the following operands:

• Constants

• Markers MD, MW, MB

• Analog inputs IA01 to IA04

– IA01: terminal I7

– IA02: terminal I8

– IA03: terminal I11

– IA04: terminal I12

• Analog output QA01

• Actual value

… QV> of another function block

Specifying the marker range without offset

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

of markers defines the source or destination range.

Specifying a 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,
