Use the DIP SW located at the side of the module to specify module allocation.

1 module is equivalent to 1 I/O module with 16 words analog input and 16 words analog output. Max. 4 modules (64 words

input, 64 words output) transmission is available. It seems as if max. 4 I/O modules are mounted to 4 slots via Device-

Net.

Note: Do not mount any modules in the slots which are occupied by virtual modules. If a real I/O module is mounted in the

slot, an internal bus error occurs and the ERR LED turns on. Max. 16 real I/O modules and virtual modules are available.

The interface module can not read the data for more than 16 modules.

to 5 is occupied. That is, R3-NE1 recognizes R3-SV4 mounted on Slot No.1 as it is and recognizes R3-GD1 mounted on Slot No.2

as divided into four modules and occupying Slots No. 2 to 5.
