Functional Description
3-3
Data required by the drive on a continuously updated basis is sent (to the
drive) using the method of data transfer described above. The rate of data
transfer is determined by the standard conventions for determining the I/O
update interval of the I/O scanner for the particular PLC Controller used.

Discrete PLC Controller I/O Example
Figure 3.2 illustrates an application where the Node Adapter Board has
been setup for a full rack (numbered rack 2) and the 16 bit words for group
1 and 2 are being used by the PLC Controller program for data transfer
with the drive. In this example, the drive has been configured so that the
data coming into source parameter 300 is sent to Logic Cmd 1 (Parameter
150). Information sent to the drive using the 16 bit output word for group 1
of rack 2 must therefore be a 16 bit logic word where the bits are defined
by the description of Parameter 150.
