Reset Safety I/O Device
Ownership
When the controller project is online, the Safety tab of the Module Properties
dialog box displays the current configuration ownership. When the opened
project owns the configuration, Local is displayed. When a second device owns
the configuration, Remote is displayed, along with the safety network number
(SNN), and node address or slot number of the configuration owner.
Communication error is displayed if the device read fails.
When online, click Reset Ownership to reset the
device to its out-of-box configuration.
Address Safety I/O Data
When you add a device to the I/O configuration folder, the Logix Designer
application automatically creates controller-scoped tags for the device.
I/O information is presented as a set of tags. Each tag uses a structure of data,
depending on the type and features of the I/O device. The name of a tag is
based on the device’s name in the system.
Safety I/O Modules Address Format
A Safety I/O module address follows this example.
TIP
You cannot reset ownership when there are pending edits to the module properties,
when a safety task signature exists, or when safety-locked.
