CR value Status

0 Data have not yet been received.

1 Data exchange is in progress.

2 Data exchange is successful.

3 Data exchange fails.

CR#25, 26: Destination IP

Explanations:

To set up the Slave IP address for data exchange manually, write “0” into CR#28 first before

setting up the destination IP. For example, if the user wants to set the destination IP address to

192.168.0.2, write H’0002 to CR#25 and H’C0A8 to CR#26. (K192 = H’C0, K168 = H’A8, K0 =

H’00, K2 = H’02).

CR#28: Destination Slave ID

Explanations:

When you set up the Salve ID (i.e. K1 ~ K255) for data exchange, DVPEN01-SL will

automatically search for the corresponding IP address from the Slave IP list. For example, if the

ID is set as “0”, the value in CR#25 and #26 will be regarded as the destination IP.

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 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 ~ K100) in data exchange.
