12.6.2 Function parameterization
Scan physical structure and store in the BL20-E-1SWIRE
In order for the SWIRE bus to start operation, the physical structure must match the SWIRE configu-
ration stored in the BL20-E-1SWIRE. On power up, the physical structure of the SWIRE bus is scanned
and compared with the SWIRE configuration stored in the BL20-E-1SWIRE (configuration check of
number of slaves, type and assigned address). If the physical structure of the SWIRE bus does not
match the configuration stored in the BL20-E-1SWIRE (SW LED flashing):
the physical structure of the SWIRE bus must be stored in the BL20-E-1SWIRE
or the physical structure must be corrected.
The parameter setting determines how the physical structure of the SWIRE bus is stored:
manually (see section ”Manual SWIRE configuration (default setting)”, s. S. 439)
or automatically (see section ”Automatic SWIRE configuration”, s. S. 439).
Storing with manual and automatic SWIRE configuration:
The slaves physically located on the SWIRE bus are scanned.
Each slave is assigned an address which is stored in the corresponding slave.
The configuration is stored in the BL20-E-1SWIRE.
Manual SWIRE configuration (default setting)
To store the physical structure of the SWIRE bus in the BL20-E-1SWIRE, the CFG button of the BL20-
E-1SWIRE must be pressed manually (only functions if the SW LED is flashing).
The parameter ”Disable CfG” has to be set to ”0 ” (see Module parameters (page 451))
Automatic SWIRE configuration
If the physical structure of the SWIRE bus does not match the configuration stored in the BL20-E-
1SWIRE on power up, the physical structure is stored automatically in the BL20-E-1SWIRE.
The parameters ”Disable CfG” and ”MC” have to be set to ”1” (see Module parameters (page 451))
Design. Status Comment
SOx relay x
SOx is transferred as the switch status of the contactor coil from the SWIRE bus
master to the appropriate SWIRE bus slave.
0 Out Off Contactor not switched on
1 ON On Contactor switched on
NOTE
Only the manual SWIRE configuration is possible if the ”Moeller Conformance” function is
active. The BL20-E-1SWIRE is factory set with a stored configuration of ”Zero” slaves
