Special Placement Requirements (DL230 and Remote I/O Bases)
Even though the module can be placed in any slot, it is important to examine the configuration
if a DL230 CPU is used, as can be seen in the section about Writing the Program, located in
this chapter. V-memory locations are used to extract the analog data. If the module is placed so
the input points do not start on a V-memory boundary, the instructions cannot access the data.
This also applies when placing this module in a remote base using a D2-RSSS in the CPU slot.
To use the V-memory references required for a DL230 CPU, the first input address assigned
to the module must be one of the following X locations. The table also shows the V-memory
addresses that correspond to these X locations.

Data is split over two locations, so instructions cannot access data from a DL230.
