AOI Descriptions - Allen Bradley PLC
This chapter describes the Add On Instructions (AOIs) that are available for use with the Ether-
Net/IP SmartMotor and Allen Bradley PLCs. The AOIs can be used "as is" or modified for
end-user-specific solutions.
NOTE:
Typically, only one AOI should be active at a time.
The AOIs write to a common command structure stored in the DriveStore tag, which is ini-
tialized in the SM6_Drive AOI and passed into all the other AOIs. The exception to this is when
a 32-byte connection is used. The 32-byte message frames make available the Attribute to
Get fields. When loaded with proper values, the Attribute to Get fields cause the targeted
drive to return the value of a selected Drive Attribute in the Attribute to Get fields of the
response. The Attribute to Get fields can be used in conjunction with the normal com-
mand/response fields.
