Function
Initialize marker ranges
INI
Copy marker ranges
CPY
The factory setting of this parameter is INI.

You can assign the following operands to function block inputs I1 and I2 and
NO:
•
Constant.
•
Markers MD, MW, MB.
•
Analog inputs IA01 to IA04:
•
IA01: Terminal I7.
•
IA02: Terminal I8.
•
IA03: Terminal I11.
•
IA04: Terminal I12.
•
Analog output QA01.
•
Output
QV of a different function block.

Specifying the marker range
Marker ranges can be specified with or without an offset.
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.
Marker range with offset
If you wish to work with an offset, specify one of the following variables at
