BASIC CONFIGURATIONS
The modules' addresses can be set freely from 0 to 31 regardless the mounting location. However, be sure not to use duplicated addresses.  A 4-point analog I/O module occupies 2 addresses.  E.g. when R8-SV4N is set to address 5, Input 1 and Input 2 are assigned to address 5, Input 3 and Input 4 are assigned to address 6.  In this case, do not set other I/O modules to address 6.
