-------------------------------------
Hi Chris,
unfortunately the bug is back!
I have tried with the HelloWord application to read a DATA TIME DATA like this:
{code:java}
"%DB2:12.0:DATE_AND_TIME"
{code}
but I have a Time out Exception:
{code:java}
[ERROR] 11:28:03.966 it.fox.datapicker.HelloPlc4x.main() - Timeout exception

> Project: Apache PLC4X

> Dear developers,
> I have found a bug in trying to read a Date and Time field from a S7 1200
> PLC, here are the informations to help you in fixing the code.
> I am using the HelloPlc4x application for testing, with this command line:
> {code:java}
> "--connection-string 's7://192.168.1.192' --field-addresses
> '%DB1:264.0:DATE_AND_TIME'"{code}
> The Data Block in the PLC is like in the uploaded jpeg.
> When I reach the line of code for the synchronous read request the code never
> return.
> Via Wire Shark I have captured the dialog and I found that in the Read Var
> request only 1 byte is requested instead of the expected 8.
> I have tried with the version 0.6.0 and in that release of the library are
> requested 8 byte correctly (the parsing after receiving the data fail for
> somewhat reason but via wireshark I could see that the data in the response
> is the correct Date and Time value I have on the PLC)
> I attach the pcap capture with the 0.8.0 version and for comparison the one
> with the 0.6.0
> Hope that this could help to have a more robust library.
> Regards,
> Stefano Bossi
