Data Fields
struct modbus_state_t *	State
	Pointer to the Modbus driver instance state structure.
MbMode_t	Protocol
	Protocol type for the instance: TCP, RTU or ASCII.
MbRole_t	Role
	Instance role on the Modbus: Client, Server or Sniffer.
uint32_t	RespTODefault
	Default client' timeout value in ms (can overrides in each command)
const struct MbVirtualfunc_t *	Virtualfunc
	Callbacks specific to the protocol to start/stop the protocol, receive/send data. For UART these functions are embedded in the Modbus driver (const struct MbVirtualfunc_t MbVirtualFuncRtu). For other carriers such as TLS they must be implemented on the application level.
const struct MbFunctionDescriptor_t *	FuncHandlers
	Callbacks specific to the command and being called during the command processing to perform command/unit specific task.
MbSessionClosed_t	MbSessionClosedCb
	Callback being called on the command processing end (reporting overall success/error)
const struct modbus_t *	MbClient
	For sniffer only. Modbus client instance on the same device (for confirmations sending)
