MODBUS I/O ASSIGNMENT

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. 8 modules (128 words input, 128 words output) transmission is available. This module seems as if max. 8 I/O modules are mounted to 8 slots via Modbus/TCP.
The input of the module is processed as follows.
[Modbus Communication] --> [R3-GE1 Module] --> [R3 Base] --> [R3 Communication Module]
In responding to the input, the output (Holding Register) command becomes valid via Modbus/TCP communication, and the input (Input Register) command is valid in the output.
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. Max. 16 real I/O modules and virtual modules are available. The interface module can not read the data for more than 16 modules.
