* Supports both individual and block reads
* Reads Holding Registers, Input Registers, Coils and Discrete Inputs
* Data types supported are bit, uint16, int16, uint32, int32 and float32
* Supports read of individual bit in words
* Support of individually set sampling freqency for all value read, both in individual- or block reads
* Retry logic to make connections robust
