Remarks This class realises a Modbus client using MODBUS
over UDP protocol variant. It provides functions to
establish a UDP connection to the slave as well as data and
control functions which can be used after a connection to a
slave device has been established successfully. The data and
control functions are organized into different conformance
classes.
It is possible to instantiate multiple instances of this class for establishing multiple connections to either the same or different hosts.
