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

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

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

# This is a combination of 12 commits.

# This is the 1st commit message:

Initial foray in to support for generic CIP Service Code requests

# This is the commit message #2:

No requirement for existence of .multiple segment in failed responses

# This is the commit message #3:

Correct handling of service_code operations in client connector I/O

# This is the commit message #4:

HART Requests almost working
o Cannot derive HART from Logix; service codes overlap

# This is the commit message #5:

Initial working HART I/O card request

# This is the commit message #6:

Support intermixed Tags and already parsed operation in parse_operations

# This is the commit message #7:

Test and decode the Read primary variable response, however:
o Still broken; the CIP Encapsulation path is still suppsed to be to the
  Connection Manager @0x06/1!  The 0x52 Route Path is Port 1, Address 2,
  and the message path should be to @0x035D/8.

# This is the commit message #8:

Success.  Still needs cleanup

# This is the commit message #9:

Further attempts to refine HART pass-thru.
o HART I/O card is not responding as defined in documentation

# This is the commit message #10:

Cleanups for python3, source analysis, unit tests

# This is the commit message #11:

Attempt to parse Read Dynamic Variables reply; 3 unrecognzied bytes?

# This is the commit message #12:

Update to attempt to parse real HART I/O card response
o Minimal Read Dynamic Variables status response?  Not successful
o Implement minimal simulated pass-thru Init/Query, HART commands 1,2,3
o Minor changes to client.py Send RR Data, to have timeout and ticks
  compatible with RSLogix; no difference
