Ethernet Communication Module DVPEN01-SL

DVP-PLC Application Manual

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 up 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 ~ K128) in data exchange.

CR#83: Read Length for Data Exchange

Explanations:

Setting up the Modbus address of the register for Master data exchange.

CR#84: Written-in Address for Data Exchange

Explanations:

Setting up 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 ~ K128) in data exchange.

CR#86: Transmission Address for Data Exchange

Explanations:

1. Setting up 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 (CR#29 ~ CR#68)

and number of registers (K20).

 Network Settings

CR#69: DHCP/Static IP

Explanations:

You can select either DHCP or Static IP. When the CR value is set as “0” Æ Static IP; When the

CR value is set as “1” Æ DHCP (dynamic IP).
