Chapter 5 Configure the I/O Modules
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 indicators on the Guard I/O
module are not both solid green, this state can be due to loss of ownership. The
ownership is based on the following items:
• 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 items 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 re-establish 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.
