Then, Notes and References
Replace
failed
device with
like device
dd) See Replacing a failed device
with a like device having the same
model name and device revision
for general replacement
procedure.
ee) If a Control Module (CM) or a
Sequential Control Module (SCM)
has connections to "contained"
Fieldbus parameters, they will
appear as a part of the Load List
under the device in the Load
Dialog and will be automatically
loaded. See the Load Dialog
example in the following
illustration. However, special
consideration must be given to
inactive Sequential Control
Modules.
ff) If connections to instantiable
blocks of the replaced field
device are through SCM
expressions, such an SCM will
not be automatically shown as a
part of the Load List under the
device in the Load Dialog. This
means that the SCM will not be
automatically loaded. In this case,
you must inactivate the SCM and
reload it as a separate procedure.
A device replacement can
cause changes in a device's
block layout, since the
Object Dictionary (OD) index
for an instantiated block can
change.
You must put a Sequential
Control Module in the proper
state (Idle) before you can
inactivate it.
