Configure Adapter Mode Chapter 3
Manually Configure Racks To add a rack manually to the remote I/O configuration, follow these steps.
1. On the 56RioCfgAdpt dialog box, right-click on the root of the I/O
tree, which represents the ControlLogix controller, and choose Add
Rack from the pull-down menu.
The Add/Resize Rack dialog box displays.
2. On the Add/Resize Rack dialog box, choose the Rack number (in octal),
the Start Group, the End Group, and Rack Mode (Monitor or Active).
3. Click OK.
Type Description
Active Emulates one or more remote I/O racks. The ControlLogix controller sends the rack produced/consumed data as
input data, which is then sent as remote I/O input data to the scanner on the Remote I/O network. The remote I/
O scanner sends output data for those emulated racks to the 1756-RIO module in adapter mode. The RIO module
then sends that data to the ControlLogix controller as produced/consumed input data.
Use active if you want to exchange data between a ControlLogix controller and a scanner on remote I/O.
Monitor Monitors remote I/O inputs and outputs on monitored, remote I/O racks, and passes data as produced/consumed
input data to the ControlLogix controller. This is also known as ‘Monitor mode’. Use Monitor mode if you have a
supervisory ControlLogix system that needs to collect data from older control systems with remote I/O.
