• Enable: enables or disables the point (true: point enabled, false: point disabled);

• Poll Frequency: allows to set the reading poll frequency (fast, normal, slow);
• 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:

• Read: enforces reading of the point.
