Replacement with ‘Configure Always’ Enabled
When the ‘Configure Always’ feature is enabled in RSLogix 5000 software, the
controller automatically checks for and connects to a replacement module that
meets all of the following requirements:
• The controller has configuration data for a compatible module at that
network address.
• The module is in out-of-box condition or has an SNN that matches the
configuration.
ATTENTION: Enable the ‘Configure Always’ feature only if the entire CIP Safety
Control System is not being relied on to maintain SIL 3 behavior during the
replacement and functional testing of a module.
Do not place modules that are in the out-of-box condition on a CIP Safety network
when the Configure Always feature is enabled, except while following this
replacement procedure.
