The device number and SNN make up the safety device’s DeviceID. Safety
devices require this more complex identifier to make sure that duplicate device
numbers do not compromise communication between the correct safety
devices. The SNN is also used to provide integrity on the initial download to
the 2198-Hxxx-ERS2 servo drive.
When the Logix Designer application 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.
Communication error is displayed if the module read fails. Refer to Replace an
Integrated Safety Drive in a GuardLogix System on page 184 for integrated
safety drive replacement information.
