Safety I/O Device Replacement - Allen-Bradley GuardLogix 5580 Original Instructions Manual

Chapter 3 Safety I/O for the GuardLogix Control System
26
When using a third-party module, if you connect to a safety I/O device
without a configuration signature, you must verify that a valid configuration
exists in the safety I/O device.
IMPORTANT Rockwell Automation safety I/O modules typically default to using the
configuration signature; and do not allow your system to run without
configuration signature.

Safety I/O Device Replacement

The replacement of safety devices requires that the replacement device is
properly configured, and that the operation of the replacement device is
verified.
ATTENTION: During replacement or functional testing of a device, the safety
of the system must not rely on any portion of the affected device.
Two options for I/O device replacement are available on the Safety tab of the
Controller Properties dialog box in the Studio 5000 Logix Designer
application:
• Configure Only When No Safety Signature Exists
• Configure Always
