Configuring I/O References

As I/O modules are added to the configuration, the programming
software keeps a running total of input/output memory. If the modules
added consume more than the maximum memory available, the
programming software displays the reference address of the module that
caused the error, and an error message.
You can change the I/O references assigned to a module when
configuring that module. The Memory tab for the NIU displays the sizes
of the NIU's memory tables. The maximum amount of data that an I/O
station can exchange on the Genius bus is 128 bytes of inputs and 128
bytes of outputs. The Memory tab displays the number of input bytes and
the number of output bytes that remain available when considering the
I/O modules already configured and these two 128-byte limits.

The programming software provides a Hardware Reference View that
shows what portion of each I/O table is used for each I/O module. To
view this information, right-click on the Hardware Configuration node of
the NIU target and select "Hardware Reference view".
