Logical Rack Number (SW1-1 through 6)
SW1 switches 1 through 6 assign the 1747-ASB module a starting
logical rack number in the scanner's image.
When configured as a complementary chassis (SW2 switch 3), the
1747-ASB module can appear on the RIO link as any starting logical
rack between 0 and 62 (0 to 76 octal).
When configured as a primary chassis (SW2 switch 3), the 1747-ASB
module can appear on the RIO link as any starting logical rack
between 0 and 7.
Logical rack one is the default setting as shipped from the factory.
The following table provides the logical rack numbers for PLC
processors.
