Concepts
concept	ModbusData
	Concept to check if a given Type T can be represented in modbus registers, constrains T to be at least 16-Bits or the size of a single modbus Register. The only exception being coil registers and discrete input registers, which are either directly represented as booleans or as 8 boolean values packed into 1 or more bytes.

Modbus Error Type Enum.

Enumerator
OK	Indicates no error has occured.
INVALID_ARG	A given Argument was invalid.
INVALID_RESPONSE	The Slave Device Response was invalid.
ADDRESS_UNAVAILABLE	This slave address is not available.
SLAVE_NOT_SUPPORTED	The slave does not support this function.
PORT_NOT_SUPPORTED	This Port is not supported.
INVALID_STATE	The Modbus Driver or the Device is in an invalid state.
TIMEOUT	The Driver experienced a timeout.
FAILURE	The slave device experienced an undermined failure.
ILLEGAL_FUNCTION	The received Function code is not available on the target device.
ILLEGAL_DATA_ADDRESS	The Data Address received is not available.
ILLEGAL_DATA_VALUE	The Data Value received is of an invalid length.
SLAVE_DEVICE_FAILURE	An Unrecoverable Error occured while trying to perform the request.
ACKNOWLEDGE	The Target accepted the Request but will take some time to complete it, this is returned to prevent a Timeout for complex requests.
SLAVE_DEVICE_BUSY	The Target is currently busy executing a command, retransmit the command at a later time.
MEMORY_PARITY_ERROR	The Extended File Area failed to pass a consistency check.
GATEWAY_PATH_UNAVAILABLE	No Path was found between the Input and the Output Port of the Gateway, gateway is possibly misconfigured or overloaded.
GATEWAY_TARGET_NO_RESPONSE	Gateway Target Device did not respond or does not exist.
