Chapter 5 Add, Configure, Monitor, and Replace CIP Safety I/O Devices
Replace a Device by Using the
Logix Designer Application
You can use the Logix Designer application to replace a safety I/O device on an
Ethernet network. To replace a Guard I/O module on a DeviceNet network,
your choice depends on the type of module.
If you are relying on a portion of the CIP Safety system to maintain SIL 3
behavior during device replacement and functional testing, the Configure
Always feature cannot be used. Go to
Replacement with ‘Configure Only
When No Safety Signature Exists’ Enabled on page 91.
If the entire routable CIP Safety control system is not being relied on to
maintain SIL 3/PLe during the replacement and functional testing of a device,
the Configure Always feature can be used. Go to
Replacement with ‘Configure
Always’ Enabled on page 96.
Safety I/O device replacement is configured on the Safety tab of the
GuardLogix controller.
