
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, the configuration stored in the BL20-E-1SWIRE is
compared with the SET configuration stored in the PLC.
- The SWIRE slaves that match resume data exchange.
- The operation is aborted for the SWIRE slaves that do not match.
Parameter setting:
– Parameter „MNA“ = 1 and „MC“ = 0 (see Module parameters (page 451))
12.6.3 MC (Moeller Conformance)
If the ”Moeller Conformance” function is activated, the BL20-E-1SWIRE behaves according to the
Moeller SWIRE conformance criteria. See Moeller SWIRE conformance criteria, s. S. 458.
If the physical structure of the SWIRE bus does not match the configuration stored in the BL20-E-
1SWIRE (SW LED flashing) when USW is switched on, the SWIRE bus only starts operation:
 After the physical structure was stored in the BL20-E-1SWIRE:
– Manually, by pressing CFG button (only functions if the SW LED is flashing). After the configu-
ration is stored, the physical structure is compared once more with the configuration stored in
the BL20-E-1SWIRE.
 If the physical structure of the SWIRE bus matches the configuration stored in the BL20-E-1SWIRE
the next time that U
SW
is switched on.
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).
The system retains data exchange with the functional SWIRE slaves if a modification or slave failure
is detected in the SWIRE bus during operation.
Parameter setting:
– Parameter „MC“ = 1 (see Module parameters (page 451))
