Hi Tim. This is a great question. If `bytestring_to_count("\x00\xff\xff", F)` is targeting big endian, then wouldn't the padding be to the left (e.g. "\x00\x00\xff\xff")?

@listpplo, Sorry for late response here. Were you able to figure this out or is it still an issue? I am not familiar with PySide6, but what I can recommend...

If you haven't tried this already, could you run the same code in PySide6 as the thread? Maybe there's something weird going on with the `if reconnet:` logic

@Rahul14189 I am not aware of available open source libraries that you can leverage. It depends on which FX series you're using since some PLCs only support serial communication instead...

@nishant-corp, Which variant of the FX 5U are you using? Does it come with Ethernet communication?

@nishant-corp, so I got some good news. Reading over the [FX5U Ethernet communication manual](https://eu-assets.contentstack.com/v3/assets/blt5412ff9af9aef77f/blte2d7501d0c4c1e80/64636d6d94af7412ab62833a/FX5_User_s_Manual_(Ethernet_Communication).pdf#page=48), it looks like it supports 3E frame. Before we do a bunch of work, have you...

You need to install openjdk-8-jdk in order to install the agent (e.g. on Debian/ubuntu `sudo apt-get install -y openjdk-8-jdk`). Not sure why the agent doesn't support openjdk-11-jdk like other apps...

@duffy-corelight, I've just implemented this, but still needs verification. Do you have pcaps to share? Thanks.

@duffy-corelight, [latest update](https://github.com/amzn/zeek-plugin-bacnet/commit/4f91d6a9fd1ec24b2e10216cbbab8081774d4686#diff-e971e4317e8e746322cff8d24b0eff78R275-R286) addresses this issue. Like the others, I'll let the customer close the issue if deemed as satisfied.

@duffy-corelight, lol... similar with the other one, could you share pcap also? Thanks
