Christofer Dutz commented on PLC4X-314:
---------------------------------------
So the difference between the two, is that in case of the commented out
addresses, the write operation is able to be executed in one single request.
However in the case with all, the request is automatically split up into two
requests. I think the problem might be, that the calculation of the size of a
request we perhaps are doing something wrong and sending a too big request and
the PLC is hanging up because of the invalid request.
