For some reason the response of the PLC seems not to be in *LITTLE_ENDIAN* format. Therefore, the Byte to Integer conversion in [1] results in a negative number. The issue occurs during the *symbolHandle* creation process in [2]. I had a look at the ADS specification [3] and the response should be in *LITTLE_ENDIAN* format, but for some reason it is not. As suggested by [~cdutz] we should create an option to override the endianness in the connection-string.
