Ownership

When the controller is online, the Ownership setting displays the safety controller to which the safety device is assigned.

One controller owns each safety I/O device in a safety system. Multiple controllers and multiple safety I/O devices can be used without restrictions in chassis or on networks. When a controller owns an I/O device, it stores the configuration data that you define for that device. This configuration controls how the device operates in the system.

From a control standpoint, one controller controls safety output devices. One controller also owns each safety input device. However, safety input data can be shared (consumed) by multiple controllers.

Select Reset Ownership to change the current owner of the safety device configuration. Ownership reset can only happen when the safety controller is online.
