Configure the I/O Modules by Using the Logix Designer Application Chapter 5
Save and Download the
Module Configuration We recommend that after a module is configured you save your work.
If after downloading the program the MS and NS LED indicators on the Guard
I/O module are not both solid green, this can be due to loss of ownership. The
ownership is based on the following:
• Guard I/O EtherNet IP address
• Guard I/O safety network number
• GuardLogix slot number
• GuardLogix safety network number
• Path from GuardLogix controller to Guard I/O module
• Configuration signature
If any of these change, the connection between the GuardLogix controller and
the Guard I/O module is lost, and the yellow yield in the project tree appears.
Reset ownership to reestablish the connection by using this procedure.
1. Open the safety I/O module properties.
2. Choose the Safety tab.
3. From the dialog box, choose Reset ownership.
