- 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.
The operation is aborted if the ”Moeller Conformance” function is activated. The SWIRE bus only
starts operation:
The following occurs if the PLC configuration check (PLC configuration check must be activated)
finds that the configuration stored in the BL20-E-1SWIRE does not completely match the SET con-
figuration stored in the PLC:
If the configuration check is set to line oriented or the ”Moeller Conformance” function is acti-
vated, 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.
The system behaves as follows if a modification to the bus or a slave failure is detected:
If the ”Moeller Conformance” function is activated, the system retains data exchange with the
functional SWIRE slaves.
If the ”Moeller Conformance” function is deactivated, SWIRE communication on the entire SWIRE
bus is aborted. The physical structure is then compared cyclically 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.
– Depending on the parameter settings, the data exchange is then either started or the opera-
tion is aborted:
- The data exchange is resumed immediately if the PLC configuration check is deactivated.
- If the PLC configuration check is activated and the configuration check is set to Bus-oriented,
data exchange is only restarted if the configuration stored in the BL20-E-1SWIRE matches the
SET configuration stored in the PLC. The operation for the entire SWIRE bus is aborted if they
do not match completely.
– If the PLC configuration check is activated and the configuration check is set to Slave-oriented,
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.
Line oriented configuration check (default setting)
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:
NOTE
This function is automatically deactivated if the ”Moeller Conformance” function is active.
