César García commented on PLC4X-183:
------------------------------------

Hi,

As part of the event subscription, implement diagnostic reading for S7 PLCs.

The interpreter of the information sent is done outside the driver in the S7Helper class.

The handling of fractional messages from the PLC has been tested, which happens with SSL requests.

The example of use case in this repository.
