Reg Type: allows to set the type of reading the register (input, holding);
Data Type: allows to set the read register data type (Int: 16-bits, Long: 32- bits, Float: 32-bits float-point, SInt: 16-bits with the sign, Slong: 32-bits with the sign);
Out: the current value of the read register.
The ModbusAsyncNumericPoint component offers the following action, available in the context menu:
