7-18 Communicating with Devices on a ControlNet Link
Determining the API
The API (actual packets per interval) is related to the RPI for the connection
and the NUT of the network. Use this table to select the API to enter in the
above worksheet:
Example 1: DriveLogix
Controller and Remote I/O
In the following example, one DriveLogix5730 controller controls remote
I/O through a 1794-ACN15 module.
Example 1: Controlling Remote Devices
This example has DriveLogix1 controlling the I/O connected to the remote
1794-ACN15 module. The data the DriveLogix controller receives from the
remote I/O modules depends on how you configure the remote I/O modules.
You can configure each module as a direct connection or as rack optimized.
One chassis can have a combination of some modules configured as a direct
connection and others as rack optimized.
