Sunny Net RTU driver's read schedule

Sunny Net RTU communication driver's read schedule just write single line as READ,.

 

Read schedule example)

READ,

 

If you click the icon  in protocol option part at <Figure 1>, you can see the dialog box such as <Figure 2>. You can register station and set analoge input tag to write and transmission value format which are registered in station.

If you register station and analog input tag(transmission value format) as above, it is saved at WorkDirectory\SCAN directory as INI file.

<Table 1> is description for method of writing station to communicate at INI file directly, and <Table 2> is description for analog input tag to transmit to each station and setting method for tag current value format.

Also, <Figure 5> is example of writing station to be registered, and <Figure 6> is example of writing analog input tag and tag current value format to be transmitted to each station.

File name

Method of writing for ini file

WorkDirectory\SCAN\station_%03d.ini 

%03d is communication port number between 0 and 255, here.

1) Enter the single station information per single line, and put in a ','(comma) last.

2) Enter station to be registered as decimal number.

3) You can set maximum 256 stations.

File name

Method of writing for ini file

WorkDirectory\SCAN\sun_03d_%06d.ini

 

%03d is communication port number between 0 and 255, here,

 

%06d is the registered station number between 0 and 65535.

1) It is station that is registered in each communication port.

Notice) Not registered station can't be communicated.

2) Enter the single analog input tag and current value format of tag, per single line by classifying as ','(comma).

3) Enter the tag current value format as number between 0 and 3. (Default = 0)

0 = BYTE, 1 = WORD, 2 = DWORD, 3 = FLOAT

4) It is possible to register maximum 256 analog input tags.
