TRANSMISSION DATA DESCRIPTIONS
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. R3-GD1 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.
■ WHEN R3-GD1 IS MOUNTED TO SLOT 2 (4 modules)
In practice, I/O modules are mounted to slot 1 and slot 2. The R3-NE1 in slot 7 recognizes the R3-SV4 in slot 1 directly.
However, the R3-NE1 recognizes the R3-GD1 in slot 2 as if 4 modules are mounted to from slot 2 to 5.
