Understand Integrated Safety Drive Replacement
GuardLogix controllers retain I/O device configuration on-board and are able
to download the configuration to the replacement device.
Replacing a Kinetix 5700 servo drive that sits on an integrated safety network
is more complicated than replacing standard devices because of the safety
network number (SNN). 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 Kinetix 5700 servo drive.
When the Logix Designer application is online, the Safety category of the
Module Properties dialog box displays the current configuration ownership.
When the opened project owns the configuration, Local is displayed.
A communication error is displayed if the module read fails. Refer to Replace
an Integrated Safety Drive in a GuardLogix System on page 309 for integrated
safety drive replacement information.

IMPORTANT
If the Kinetix 5700 replacement drive was used previously, clear the
existing configuration before installing it on a safety network by
resetting the drive to Hardwired STO mode. To see how this is done,
refer to Restore the Hardwired STO Mode by Using the Logix Designer
Application on page 287.
