> Issue Type: Improvement
> Reporter: Julian Feinauer
> Priority: Minor

> During discussion of
> https://github.com/apache/incubator-plc4x/pull/28
> it became clear that it is necessaary to specify the endianess when working with a modbus device.
> Currently the default is BE.
> Comment from [~cdutz]:

> We should set the endianess on a connection level. I haven't come across any PLC where the types differed. Regarding the connection string ... I would make it mandatory:
> modbus://10.10.40.10:234/LE or modbus://10.10.40.10:234/BE ... it is an important detail similar like "Rack" and "Slot" for S7.
