Ethernet Communication Module DVPEN01-SL

CR#94: Enabling the setting of an IP address

Explanations:

If the value in CR#94 is 1, the setting of an IP address will be enabled. After the setting is complete, the value in CR#94

will automatically become 0.

CR#95: Status of setting an IP adress

Explanations:

The control register is used to show the status of setting an IP address. If the value in CR#95 is 0, the setting of an IP

address is successful. If the value in CR#95 is 1, the setting of an IP address is being executed.

 Sending MODBUS TCP Instruction

CR#111: 8-bit processing mode

Explanations:

Setting the MODBUS TCP transmission mode

When the CR value is set as “0”16-bit mode; when the CR value is set as “1”8-bit mode.

CR#112: MODBUS client Keepalive time-out

Explanations:

CR#112 is the TCP Keepalive timeout for MODBUS TCP connection. (Unit: Second)

Default: 30s

If the connection idle time becomes longer than the keep-alive time-out, DVPEN01-SL will cut off the idle connection.

CR#114: MODBUS TCP timeout

Explanations:

Setting the communication time-out (in ms) for MODBUS TCP mode

CR#115: MODBUS TCP trigger

Explanations:

When the CR value is set as “1”, MODBUS TCP will be triggered. After the data transmission is completed in MODBUS

TCP mode, the CR value will automatically be reset to “0”. Please trigger by differential instructions.

CR#116: MODBUS TCP status

Explanations:

Displaying the current communication status of MODBUS TCP mode

When the CR value is set as”0”the data have not yet been received; when the CR value is set as “1”the data

exchange is in progress; when the CR value is set as “2”the data exchange is successful; when the CR value is set

as “3”the data exchange fails.
