Configure Modules with the Logix Designer Application Chapter 5
Save and Download Module
Configuration We recommend that after a module is configured you save your work.
If after downloading the program the MS and NS status indicators on the Guard
I/O module are not both solid green, this may be due to loss of ownership. The
ownership is based on the following:
· Guard I/O DeviceNet node number
· 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 using this procedure.
1. From the Module Properties dialog box, click the Safety tab.
2. Click Reset Ownership.
3. Click OK.
