Item 2 — controller-discovered UDT members are writable on both transports once browse-committed and authored ReadWrite (writability is the operator's: the commit lands AccessLevel Read with no writable key). The write names the member (one CIP symbolic segment per member), its own type, its own bytes. BIT members are supported: Z-35162 (read-only probe) exposes a UDT BIT member as a 1-byte 0xC1 BOOL, so the controller applies the bit and the hidden host's other bits are never in the request. - AbCipDriver: pre-write width check on BOTH transports (libplctag patched part of its read buffer and sent it all): BadTypeMismatch, Bool over a wider value BadNotSupported; nothing sent, handle kept, health untouched, warn once. - A runtime NotSupportedException is a refusal: no longer latches Degraded. Item 3 — whole-UDT writes refused BadNotSupported before any runtime exists, by decision (a structure write overwrites hidden hosts + padding), documented. ab_server patch 0003: serve member paths from dotted flat tags (UdtSeg.*), and accept libplctag's pad byte on 1-byte writes (stock ab_server refused every libplctag BOOL/SINT write with 0x03). New AbCipUdtMemberWriteTests (both transports), AbCipDiscoveredMemberWriteTests, native request-byte theory, and a browse-commit mapper pin.

# AB CIP integration-test fixture — ab_server (libplctag).
|
|
#
|
|
# One service per family. All bind :44818 on the host; only one runs at a
|
|
# time. Commands mirror the CLI args AbServerProfile.cs constructs for the
|
|
# native-binary path.
|
|
#
|
|
# Usage:
|
|
# docker compose --profile controllogix up
|
|
# docker compose --profile compactlogix up
|
|
# docker compose --profile micro800 up
|
|
# docker compose --profile guardlogix up

# The last three are here for the controller-browse gate (Gitea #468) and
|
|
# are additive — the read/write suites key off the Test* tags above.
|
|
# The UdtSeg.* tags (Gitea #611) stand in for the members of a UDT tag `UdtSeg`
|
|
# (modelled on the Z-35162 press's UDT_TemperatureProfile_Segment): ab_server has
|
|
# no structures, so patch 0003 serves a member path (one CIP symbolic segment per
|
|
# member) from the flat tag whose --tag name is that dotted path. They exist for
|
|
# the discovered-member write suite (AbCipUdtMemberWriteTests); a bare `UdtSeg`
|
|
# read stays unknown, as does any member not listed here.
|
|
# Odd-length names are deliberate: Symbol Object entries are packed with no
|
|
# padding, so a name with an odd byte count puts every following entry on an
|
|
# odd offset. A decoder that assumes even alignment reads all six correctly
|
|
# and then loses everything after the first odd name.
