The required Logix controller can then be chosen by selecting it and clicking the Ok button, or
by double-clicking on the controller module.
A maximum number of 3 controller mapping entries can be added.
NOTE: A maximum of 230 bytes can be exchanged per mapped item when
running in Scheduled Tag Mode. Thus if the user needs to exchange 130 x 32bit
values from/to the Scheduled Tag DNP3 Router three mapped items will be
required. The first and second mapped items can each transfer a maximum of
57 x 32bit values (228 bytes) whilst the third mapped item just needs to
transfer the last 16 x 32bit values. This is shown in the figure below:
