After the physical structure was stored in the BL20-E-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 has been rectified.
If the PLC configuration check is activated, data exchange is only started if the configuration stored
in the BL20-E-1SWIRE fully matches the SET configuration stored in the PLC. If the two configura-
tions 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 configura-
tion stored in the BL20-E-1SWIRE.
The SWIRE bus starts operation as soon as the matching configurations are detected:
– After the physical structure was stored in the BL20-E-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 has been rectified.
Depending on the parameter settings, the data exchange is then either 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 BL20-E-1SWIRE fully matches the SET configuration stored in the PLC. The opera-
tion for the entire SWIRE bus is aborted if they do not match completely.
Parameter setting:
Parameter „MNA“ and „MC“ = 0 (see Module parameters (page 451))
Slave oriented configuration check
If the physical structure of the SWIRE bus does not match the configuration stored in the BL20-E-
1SWIRE on power up (SW LED flashing), the physical structure is compared continuously with the
configuration stored in the BL20-E-1SWIRE. The SWIRE bus starts operation as soon as the matching
configurations are detected:
After the physical structure was stored in the BL20-E-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 has been rectified.
If the PLC configuration check is activated, data exchange is started with all SWIRE slaves that match
the SET configuration stored in the PLC. The SWIRE slaves that do not match the SET configuration
stored in the PLC do not perform any data exchange.
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 configura-
tion stored in the BL20-E-1SWIRE.
NOTE
This function is automatically deactivated if the ”Moeller Conformance” function is active.
