RIO Installation
Connection to an Allen-Bradley RIO network requires two basic
procedures:
S The MCA board DIP switches must be configured for the desired setup.
S The physical wire connections to the board are made.
Switch settings for RIO rack size (switch U5 channel A, and U14
channel B):
Switch positions 6–8 set the rack size for the MCA board. The size
determines how much real time data can be transferred between the Drive
and PLC Controller. Refer to table 4–E for switch setting details.
