108 Maintain Your Modules
Publication 1791DS-UM001H-EN-P - April 2009
Replace Modules
The network consists of the DeviceNet master unit and safety I/O
modules. The entire network is affected when a safety I/O module is
faulty, so a faulty module must be repaired or replaced quickly. We
recommend having spare modules available to restore network
operation as quickly as possible.
Observe the following precautions when replacing a faulty module.
• After replacement, be sure there are no errors with the new
module.
• When returning a module for repair, attach a detailed
description of the problem and return the module to your
Rockwell Automation representative.
• If there is a faulty contact, wipe the contact with a clean,
lint-free cloth dampened with alcohol.
Perform a system test of the related safety functions after
IMPORTANT
replacing a module.
After replacing a module, set the new module's switches to the same
settings that were on the old module. For related information see the
following publications.
• GuardLogix Controllers User Manual, publication 1756-UM020,
for information on replacing a module in the system
• GuardLogix Controller Systems Safety Reference Manual,
