Operating Modes of the Transfer Data Block Function Block
Inputs
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,
• Analog input IA..,
• Analog output QA..
The value at the input is taken as the offset to marker MB01.
