Bus-oriented
configuration check
(default setting)
If the physical structure of the SWIRE bus does
not
match the configuration stored
in the XNE-1SWIRE on power up (SW LED flashing), the physical structure is
compared continuously 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.
If the PLC configuration check is activated, data exchange is only started if the
configuration stored in the XNE-1SWIRE fully matches the SET configuration stored
in the PLC. If the two configurations do
not
match completely (RDY LED flashing),
the operation is aborted for the entire SWIRE bus (RDY LED flashing).
SWIRE communication is aborted for the entire SWIRE bus, if a bus modification or
slave failure is detected during operation. The physical structure is then compared
cyclically 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.
•
According to the parameter settings, the data exchange is then started or the
operation is aborted:
• The data exchange is resumed immediately if the PLC configuration check is
deactivated.
• If the PLC configuration check is activated, data exchange is only restarted if
the configuration stored in the XNE-1SWIRE fully matches the SET configura-
tion stored in the PLC. The operation for the entire SWIRE bus is aborted if
they do
not
match completely.
Parameter setting:
•
PROFIBUS-DP and CANopen (Byte 1):
• MNA = 0 (MXpro: «configuration check» = bus oriented) and
• MC = 0 (MXpro: «Moeller compliant» = deactivate)
•
DeviceNet (Attribute 121 (79
hex
) «PARAM_COMMON_OERATION_MODES»):
• Bit 3 = 0 and
• Bit 4 = 0
This function is automatically deactivated if the «Moeller Conformance»
function is active.
