0x002a Configure length of
the outgoing process data
packets
In this memory register you have the option, to define the size of the
process data output area.
You can find further information in section "DPR - Dual Port RAM
[
}
29]".
This value has a header of 2 bytes. When specifying the value, you
must
not
include the length of the header for the required data size,
however.
Make sure that the sum total of the values in the Memory Register
0x0027-0x002a does not exceed the configurable total size of the
DPR. This total size of 1024 bytes is made up as follows:
– Header: 40 bytes
– Configurable size: 984 bytes
