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. R3-GE1 seems as if max. 8 I/O modules are mounted to 8 slots via Mod-
bus/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 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-GE1 IS MOUNTED ON SLOT NO. 2 (4 modules)
Real I/O modules are mounted on Slots No. 1 and 2, however, the network module (R3-NC3) recognizes that each of Slots No.
1 to 5 is occupied. That is, R3-NC3 recognizes R3-SV4 mounted on Slot No.1 as it is and recognizes R3-GE1 mounted on Slot
No.2 as divided into four modules and occupying Slots No. 2 to 5.
