...
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 function block input >I1 or >I2.
• Constant.
• Output ..QV of a function block.
The value at the input is taken as the offset to marker byte
MB01.
h
With the offset information you can address marker
ranges (for example MB380), which you can not address
when using marker operands (direct addressing).
Offset calculation for addressing marker words:
Offset = MW (x - 1) x 2
Offset calculation for addressing marker double words:
Offset = MD (x - 1) x 4.
Coil
The coil of the function block is used in the standard circuit
diagram to transfer the input value.
Parameters
