Explanation

The sum of the length of the status word of RTU-DNET and the input data of the module connected to it.

Unit: byte

The sume of the length of the control word of RTU-DNET and the output data of the module connected to it.

Unit: byte

The number will be regarded as 8 when it is less than 8 and as 16 when it is bigger than 8 but less than 16.

Unit: bit

The number will be regarded as 8 when it is less than 8 and as 16 when it is bigger than 8 but less than 16.

Unit: bit

The number of special modules connected to RTU-DNET

The length of input data of the special module connected to RTU-DNET.

Unit: word

The length of output data of the special module connected to RTU-DNET.

Unit: word

Displaying the status of RTU-DNET. See 4.3 for more details.

For setting up the mode of RTU-DNET, e.g. “H8000” for STOP mode and “H8001” for RUN mode.

See 4.3 for more details.

The interval when RTU-DNET executes diagnosis.
