Unable to list identity #9

Closed bafeigum closed 8 years ago

bafeigum commented 8 years ago

Using the example EthernetIP-server.py code, I am unable to process the ListIdentity command (0x63). Is this command supported? It should be returning the default Logix identity specified in device.py, but I keep getting an EtherNet/IP error.

Here is the log I am getting.

Unfortunately, cpppo doesn't (yet) support either the List Identity command, or UDP connections. However, this is something I am working on -- no ETA yet...

pjkundert commented 8 years ago

The basic List Identity framework is implemented, in branch feature-list-identity. Comments welcome, as I complete the feature...

pjkundert commented 8 years ago

Fixed in branch feature-list-identity. I'll be merging it onto master next week, and pushing Version 3.9.0
