31
Bits 1—31 are one-to-one mapped to controller addresses 1—31. The bit value is set to 1 only
when there are no conflicts with that address.
For example,
1,2, and 7 and more than one controller at address 23, this query will return 135. The binary
representation of 135 is 10000111. Bit #0 = 1 implies that the scan found at least one address
conflict during last scan. Bit #1,2, 7 = 1 implies that the scan found controllers with addresses
1,2, and 7 that do not conflict with any other controller.
