Ethernet Communication Module DVPEN01-SL
DVP-PLC Operation Manual

CR#29~48:
Data transmission buffer
Explanations:
Storing the data to be transmitted to the remote MPU.
CR#49~68:
Data receiving buffer
Explanations:
Storing the data received from the remote MPU.
CR#81:
Read address for data exchange
Explanations:
Setting manually the MODBUS address of the register for Slave data exchange
Only register address is allowed (e.g. D0=H’1000).
CR#82:
Read length for data exchange
Explanations:
The number of receiving registers (K1~K100) in data exchange.
CR#83:
Read length for data exchange
Explanations:
Setting the MODBUS address of the register for Master data exchange
CR#84:
Written-in address for data exchange
Explanations:
Setting manually the MODBUS address of the register for Slave data exchange
CR#85:
Written-in address for data exchange
Explanations:
The number of transmission registers (K1~K100) in data exchange
CR#86:
Transmission address for data exchange
Explanations:
1. Setting the MODBUS address of the register for Master data exchange.
2. Example: Write H’1000 (D0) into CR#81, K1 into CR#82, and H’1064 (D100) into CR#83. If the data
exchange is successful, the value in D0 of the Slave will be written into D100 of the MPU. Or write H’1002 (D2)
into CR#84, K4 into CR#85, and H’1008 (D8) into CR#86. If the data exchange is successful, the value in
D8~D11 of the Master will be written into D2~D5 of the Slave. Both sending and receiving can be executed at
the same time. When the values in CR#82 and #85 are both “0”, DVPEN01-SL will use the default registers
