The source for the input word(s) and the destination of the output word(s) in the
internal database is user configured via the CFG file (See [RIO] section in this
manual). Each word is associated with an independent register in the database.
The following illustration shows the relationship between the internal database,
the input map and processor input image:

The Input Map acts as a data routing table,
allowing the user to configure the source of data
for the Input Image transferred to the RIO scanner
processor on a high-priority basis.
Module Database
The same relationship exists for the output image except the data is transferred
from the PLC to the module’s database.
