Placing and Configuring Local I/O 4-5
Configuring a DIN Rail When you create a DriveLogix project, the programming software
automatically creates the DIN rail for the project. You must configure the
DIN rail.
You must specify these characteristics:
• On the General tab, specify the size of the chassis. Enter the number of
modules (1-8) that you plan to install on the rail. The controller uses this
chassis size to determine the size of tag for the rail’s rack-optimized
data.
• On the Connection tab, specify the RPI. The RPI of the DIN rail
applies to all the I/O modules you install on that DIN rail.
1. In the Controller Organizer, select the local (Local) rail of the controller.
Right-click and select Properties.
2. Specify the configuration options for the rail.
IMPORTANT
Set the RPI of the DIN rail to a minimum of 30 ms. I/O
function will be intermittent if the value is set lower,
IMPORTANT
If there are no modules installed on a rail, make sure to
inhibit that rail.
