-----------------------------------
Summary: Writing byte array not working
Key: PLC4X-309
URL: https://issues.apache.org/jira/browse/PLC4X-309
Project: Apache PLC4X
Issue Type: Bug
Components: Driver-S7
Affects Versions: 0.8.0
Environment: Windows 10
Reporter: Maida Baralić
Attachments: DB4.pdf, PLCWrite.zip, write_byte_array_0.8.0.pcapng
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.
