Chapter 5 Configure the Encoder with Studio 5000 Environment
If the safety task has a safety task signature, the GuardLogix controller
automatically configures the replacement CIP Safety I/O device only if the
following is true:
– The device already has the correct safety network number.
– The device electronic keying is correct.
– The node or IP address is correct.
For detailed information, see Additional Resources
on page 9 for the
appropriate user manual for your GuardLogix or Compact GuardLogix
controller.
•Configure Always
With this setting enabled, the controller automatically checks for and
connects to a replacement encoder that meets the following requirements:
– The controller has configuration data for a compatible encoder at that
network address
– The encoder has an SNN that matches the configuration
ATTENTION: Enable the Configure Always feature only if the entire integrated
safety control system is not being relied on to maintain SIL 3 behavior during
the replacement and functional testing of an 843ES CIP Safety encoder.
If other parts of the integrated safety control system are being relied upon to
maintain SIL 3, make sure that the controller’s Configure Always feature is disabled.
It is your responsibility to implement a process to make sure that proper safety
functionality is maintained during device replacement.
ATTENTION: Do not place any devices in the out-of-box condition on any
integrated safety network when the Configure Always feature is enabled. For
the device replacement procedure, see Additional Resources
on page 9 for the
appropriate user manual for your GuardLogix or Compact GuardLogix controller.
