12.6.9 Moeller SWIRE conformance criteria
The SWIRE system was developed by Moeller. The BL20-E-1SWIRE supports the SWIRE slaves SWIRE-
DIL. For this particular requirements must be fulfilled to ensure compatible operation. The ”Moeller
Conformance” function is supported from version VN 01-04.
Special system behavior with the ”Moeller Conformance” function
The following applies if the ”Moeller Conformance” function is activated.
 The following functions are automatically deactivated:
– Automatic SWIRE configuration
– Bus oriented configuration check
– Slave oriented configuration check
 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).
 he physical structure of the SWIRE bus is scanned once and compared with the SWIRE configura-
tion stored in the BL20-E-1SWIRE once when U
SW
is switched on, or after a new configuration is
stored (by pressing the CFG button while the SW LED is flashing).
 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 configuration 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.
 Even if the ”Moeller Conformance” function is activated, the physical structure of the SWIRE bus
is continuously monitored during operation. However, data exchange continues with function-
ing slaves if slave failures occur. Not until the next power up is operation of the bus with faulty
slaves discontinued.
NOTE
The ”Moeller Conformance” function is deactivated by default.
