2.2.4
System behavior with negative configuration checks and slave failure
The system behavior when the result of a configuration check is negative, depends
on the individual parameter settings:
The following occurs if the physical structure of the SWIRE bus is found not to match
the configuration stored in the XNE-1SWIRE on power up (SW LED flashing):
•
If the
«Moeller Conformance»
function is
deactivated
, the physical structure
is continuously compared with the configuration stored in the XNE-1SWIRE. The
SWIRE bus starts operation as soon as the matching configurations are
detected:
• After the physical structure was stored in the XNE-1SWIRE:
• Automatically (if the automatic SWIRE configuration is activated)
• Or manually (if the automatic SWIRE configuration is deactivated),
by pressing the CFG button (only functions if the SW LED is flashing).
• After the physical structure is corrected.
•
The operation is aborted if the
«Moeller Conformance»
function is
activated
.
The SWIRE bus only starts operation:
• After the physical structure was stored in the XNE-1SWIRE and a match was
determined:
• Manually, by pressing the CFG button (only functions if the SW LED is
flashing).
After the configuration is stored, the physical structure is compared once
more with the configuration stored in the XNE-1SWIRE.
• If the physical structure of the SWIRE bus matches the configuration stored
in the XNE-1SWIRE the next time that U
SW
is switched on.
The following occurs if the PLC configuration check (PLC configuration check must
be activated) finds that the configuration stored in the XNE-1SWIRE does not
completely match the SET configuration stored in the PLC:
•
If the configuration check is set to
Bus-oriented
or the
«Moeller Confor-
mance»
function is
activated
,
the operation is aborted for the entire SWIRE bus
(RDY LED flashing).
•
If the configuration check is set to
Slave-oriented
:
• The SWIRE slaves that match are ready for data exchange.
• The operation is aborted for the SWIRE slaves that do not match.
CAUTION
SWIRE bus energized
Any manipulation of the physical structure (e.g. exchange of the
SWIRE slaves) may damage the device.
▶
De-energize the SWIRE bus before carrying out any changes.
The following functions are deactivated if the «Moeller Conformance»
function is active:
• Automatic SWIRE configuration
• Bus-oriented configuration check
• Slave-oriented configuration check
