TOPIC: How to send modbus rtu command to device

David,

You have to setup Control property in Slider: teslascada.com/HTML/control-(for-sliders).html
Minimum: 0, Maximum: 255. And test it in TeslaSCADA2 Runtime.

Ruslan:

Yes ,I had add slider value from 0 to 255 , but our teslascada2 still can't send command to our device when I monitor the information of modbus 485, my simple modbus command such as below
01 10 27 10 00 01 02 00 FF (01 my device ID ; 10 27 my address of register 10000 start ; 00 01 my quantity value ; 02 my data quantity ; 00 FF my device change value) , follow your command and I still can't depend on teslascada2 to operate my device , How do I do ?

Do you use TeslaSCADA2 Runtime to connect to your device?
Can you read registers from your device? Try to check communication by using Wireshark.
