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.

Modbus/TCP master:
I/O expansion with remote I/O, e.g. R3 or R7 series, is available. Measuring points in multiple locations can be handled collectively.
SLMP Client:
DL8 allows I/O expansion by connecting with the SLMP-compatible CPU unit of Mitsubishi programmable-controller MELSEC; and collectively handles data from measuring points in multiple locations.
