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 ~ K100) 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).

Sending Modbus TCP Instruction

CR#111: 8-bit Processing Mode

Explanations:

Setting up the Modbus TCP transmission mode. When the CR value is set as “0” Æ 16-bit mode; when the CR value is set as “1” Æ 8-bit mode.

CR#112: Modbus Client Keep-Alive Time-out

Explanations:

CR#112 is the TCP Keep-Alive time-out for Modbus TCP connection (s). Default: 30s. If the connection idle time becomes longer than the keep-alive time-out, DVPEN01-SL will cut off the idle connection.
