Christofer Dutz commented on PLC4X-182:
---------------------------------------
The S7 Driver now should generally auto-split large requests into multiple
requests. However the only thing missing is that if one item size exceeds the
size of a message, this causes failure. Here we need to split up the array into
multiple parts and join them back together. In the 0.6 branch it was
implemented this way, this still needs to happen on the new version on develop.

> Project: Apache PLC4X
> Issue Type: Improvement
> Components: Driver-S7
> Reporter: César García
> Assignee: César García
> Priority: Major
> Fix For: 0.6.1
>
>
> # A request with many Items is divided within the limits allowed by the size
> of the PDU.
> # If one of the requested Items exceeds the size of the PDU it is trimmed to
> the maximum size of the PDU. The existing code tries to split the message,
> but it fails. This generates an unsafe condition.
> # Rethink the routine for handling long messages, as an additional layer in
> Netty.
