Configuration of a Replaced AS-Interface V2 Slave
AS-Interface Configuration
Automatic Configuration
When a slave must be replaced, it can be automatically replaced with a slave with
the same AS-Interface profile.
This happens without the AS-Interface V2 Fieldbus having to stop, and without
requiring any manipulation if the configuration mode’s Automatic addressing utility
is active (see page 112).
The replacement slave must initial have the address 0 (a new slave is usually factory
set with a default address of 0), and the same profile as the slave it will replace. It
will automatically assume the address of the replaced slave once installed, and will
then be inserted into the list of detected slaves (LDS) and the list of active slaves
(LAS).
Manual Configuration
Alternative options without automatic addressing are available:
You can configure the replacement slave with the same address as the slave it
will replace using the pocket programmer. As previously noted, the replacement
must have the same product reference number and the same profile and subprofile
of the slave to replace. It is thus automatically inserted into the list of
detected slaves (LDS) and into the list of active slaves (LAS). This feature is
available only if one, and not more than one, slave is inoperative.
Change the address using the Scan For Devices window (see page 100).
