Configuration

The DeviceNet Module is a Group 2 slave device, using a predefined master/slave connection set. I/O data is produced and consumed
using polled I/O messaging.
The soft starter must be added to the DeviceNet manager project using the EDS file and configuration/management software tool. This
file is available on the supplied CD or can be downloaded from the website www.controltechniques.com
successfully, the correct EDS file must be used.
