6. Function blocks
6.1 Manufacturer function blocks
Update
After importing projects created with earlier versions of the programming software
easySoft, check whether the "without offset" address type was used. If it was, you will
need to reprogram the relevant parameters and replace the marker operands with con-
stants.
Offset calculation for addressing marker words
Offset = MW (x-1)*2
Offset calculation for addressing marker double words
Offset = MD (x-1)*4
Parameter error due to incorrect number or offset definition
Bad parameter configurations will be output at program runtime via error outputs E1
through E3.
This type of parameter configuration error will occur, for example, when the number of
elements exceeds the source or destination range or, due to an offset error, the source
or destination range falls outside the available marker range.

the reference data block or
offset added to marker byte MB01 when
using one of the operands specified
above.
I2
Destination range
