> Environment: Windows 10
> Reporter: Maida Baralić

> I'm having some issues with writing a byte array using S7 driver to the
> S7-1200.
> I'm a bit new to the communication with PLCs, so I'm not sure if I'm doing
> something wrong.
> I've followed the example of how to write a byte array to the connection,
> however I'm getting an INTERNAL_ERROR as a response code from the library and
> in the Wireshark the status from the PLC is inconsistent data type.
> I've attached both the sample project that's not working for me, my
> definition of byte array on the PLC and also Wireshark capture.
> It's possible that I'm not doing something right, however I can't figure it
> out.
> Writing of most of the single values is working, however the array is the
> problem. And as far as I understood from the code and documentation arrays
> should be supported.
> Any help would be appreciated.
