Julian Feinauer commented on PLC4X-64:
--------------------------------------
[~timbo2k],[~cdutz] I just read the MODBUS Spec
(http://www.modbus.org/docs/Modbus_Messaging_Implementation_Guide_V1_0b.pdf)
and on Page 6 it states
> Remark : the different fields are encoded in Big-endian.
So I guess this is obsolete, as it is specified, or?
> The Modbus connection string should be extended with ENDIANESS Information

> Key: PLC4X-64
> URL: https://issues.apache.org/jira/browse/PLC4X-64
> Project: Apache PLC4X
> 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]:
> {noformat}
> 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.
