"illegal syntax in expresion" Modbus Address in Datamod for RTU 485

I try to make a command in datamod for modbus RTU 485 with Address 030A but its error “illegal syntax in expresion”, is there any way to work around it?

Hello,

If you want to use hexadecimal in data object, $ symbol is required before the number.
So, 0778 and $030A are same.

Please check this Automation Help: Number syntax
