Function 16 Modbus

Hello.

How can I write multiple registers using the modbus 16 function with UBUS?
I have tried to do it through the WEB UI, however I only have 3 fields to query the slave: “Function”, “First register number”, “Register count/Values”.
For example, how can I send a modbus message like this. :
I use serial Modbus Master

Hello,

In order to write multiple values using the Modbus Master, the values need to be separated by space characters:

So in your case, the values within the REGISTER COUNT / VALUES field will be 000A 0102.

Best regards,
