Replacing POINT Guard I/O Modules
This chapter provides information on replacing POINT Guard I/O modules
when they are connected to GuardLogix or SmartGuard controllers. For more
information on these controllers, refer to the controller publications listed in the
Additional Resources on page 13 .
A major difference in functionality between the GuardLogix and SmartGuard
safety controllers affects the replacement of safety I/O modules. GuardLogix
controllers retain I/O module configuration on-board and are able to download
the configuration to the replacement module. SmartGuard controllers do not
retain I/O module configuration, so you need to use RSNetWorx for DeviceNet
software to download the configuration to the replacement module.
The Safety Network Number Replacing a safety I/O module that sits on a CIP safety network is more
complicated than replacing standard devices because of the safety network
number (SNN). The module number and SNN make up the safety module’s
DeviceID. Safety devices require this more complex identifier to make sure that
duplicate module numbers do not compromise communication between the
correct safety devices.
