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.
Parameter Function
INI Initialise marker ranges
CPY Copy marker ranges
