Digital Module Operation in a Control System Chapter 1
Configuration Signature and Ownership
Every Compact 5000 I/O safety module in a system has a configuration
signature and configuration ownership.
Configuration Signature
Each safety device has a unique configuration signature that defines the
module configuration. The configuration signature includes the following:
• ID number
•Date
•Time
The configuration signature is used to verify a module’s configuration.
Configuration Ownership
The connection between the owner-controller and the Compact 5000 I/O
safety module is based on the following:
• Compact 5000 I/O safety module node number
• Compact 5000 I/O safety module safety network number
• Controller node or slot number
• Controller safety network number
• Path from the controller to the Compact 5000 I/O safety module
• Configuration signature
If any differences are detected, the connection between the owner-controller
and the Compact 5000 I/O safety module is lost, the yellow yield icon appears
in the controller project tree.
IMPORTANT If the owner-controller is a Compact GuardLogix 5380 controller, the
controller has a node number.
If the owner-controller is a GuardLogix 5580 controller, the
controller has a slot number.
