3-6 Placing and Configuring Local I/O
On the General tab, specify the size of the chassis. Enter the number of
modules you plan to install. Include the DriveLogix5730 controller and
drive in this total, along with a maximum of 16 I/O modules, not including
the power supply.
The Comm Format for the CompactBus is automatically set to Rack
Optimized and cannot be changed.
Using the Connection tab, you can specify the RPI for the systems and
choose to inhibit or uninhibit the CompactBus.
The RPI you specify here is the RPI for every 1769 module on this
controller's local CompactBus. Specify an RPI from 1-750ms for the
system. You do not specify individual RPI values for each module.
By inhibiting and uninhibiting the CompactBus, you can write new
configuration data to the entire system at once.
The controller's response to a CompactBus connection failure is fixed to
always fault the controller. It is not configurable.
