E40 Process Jobs + E94 Control Jobs + E30 communication state
GEM300 layer: SEMI E40-0705 Process Job and E94-0705 Control Job state machines, plus the E30 §6.1 communication-state machine that sits between HSMS SELECT and full GEM communication. Data-driven via data/process_job_state.yaml and data/control_job_state.yaml, mirroring the existing control_state.yaml pattern. Wire coverage: S14F9/F10 CreateObject (CJ) host -> equipment S14F11/F12 DeleteObject (CJ) host -> equipment S16F5/F6 PRJobCommand host -> equipment S16F9 PRJobAlert equipment -> host S16F11/F12 PRJobCreate (simplified body) host -> equipment S16F13/F14 PRJobDequeue host -> equipment S16F27/F28 CJobCommand host -> equipment Process Job FSM exposes 8 states matching PRJOBSTATE bytes (E40 §10.3.2); HOQ is reorder-aware (move-to-head against an insertion-order vector); Stop/Abort on a Queued PJ routes through ABORTING so the host observes PRJOBSTATE=7 on the wire (§6.3); alert_enabled is settable per-PJ for PRALERT control; FSM dispatches through ProcessJobStore::on_change_ dynamically so a late set_state_change_handler() reaches existing PJs. Hardening: loader rejects NoState (sentinel) as initial/from/to and rejects `on: created` rows; static_asserts pin enum values to wire bytes; ProcessJobStore is non-movable to keep the per-PJ this-capture safe. Server simulator cascades the full CJ -> PJ lifecycle on CJSTART so the wire trace exercises every legal state. CEIDs 400/401 fire on CJ state changes via the existing event-report pipeline. Tests: 60+ new assertions across test_process_jobs, test_control_jobs, test_communication_state, test_hsms_connection, plus loader and messages round-trip coverage.

Initial commit: C++20 SECS-II / HSMS / GEM client + server
A fully containerised SECS/GEM toolchain. Single docker compose project,
no host build tools. 63 unit-test cases / 278 assertions, two demo
executables, end-to-end two-container demo exercising every implemented
capability.
Architecture (bottom-up):
secs2/ E5 SECS-II codec
Item variant over L/A/B/BOOLEAN/I1-8/U1-8/F4/F8
encode/decode big-endian, 1/2/3-byte length encoding
Message SxFy + W-bit + optional root item
to_sml human-readable text rendering
hsms/ E37 HSMS transport (TCP)
Header 10-byte header + SType enum (Data/Select/Deselect/
Linktest/Reject/Separate)
Frame 4-byte length prefix + payload encode/decode
Connection async Asio TCP, NOT-SELECTED -> SELECTED state machine,
T3/T5/T6/T7/T8 timers, system-bytes reply correlation,
graceful close-after-flush separation
endpoint active Client (connect with T5 retry) and passive Server
(accept loop) wrappers over Connection
gem/ E30 GEM logic
ControlStateMachine 5-state E30 control model with operator
actions, host requests, SEMI-mandated ack
codes (OnlineAck, OfflineAck, CommAck), and
a state-change handler
EquipmentDataModel in-memory dictionary: SVIDs, DVIDs, ECIDs
(with EAC), CEIDs, report defs, CEID->report
links, enabled-events set, alarm table
(ALCD, enabled, active), process programs,
host command registry, clock (16-char
YYYYMMDDhhmmsscc with offset)
messages.hpp builders + parsers for every SxFy below
GEM message coverage (full list):
S1F1/F2 Are You There / On Line Data
S1F3/F4 Selected Equipment Status Request / Data
S1F11/F12 Status Variable Namelist Request / Data
S1F13/F14 Establish Communications (+ CommAck)
S1F15/F16 Request OFFLINE (+ OfflineAck)
S1F17/F18 Request ONLINE (+ OnlineAck)
S2F13/F14 Equipment Constant Request / Data
S2F15/F16 EC Send + EquipmentAck (Accept/UnknownEcid/Busy/OutOfRange)
S2F17/F18 Date and Time Request / Data
S2F29/F30 Equipment Constant Namelist Request / Data
S2F31/F32 Date and Time Set Request / TimeAck
S2F33/F34 Define Report + DefineReportAck (5 enum values)
S2F35/F36 Link Event Report + LinkEventAck
S2F37/F38 Enable / Disable Event Report + EnableEventAck
S2F41/F42 Host Command + HostCmdAck (7 values) + per-param CPACKs
S5F1/F2 Alarm Report Send + AlarmAck (ALCD bit-7 set/cleared
+ lower-7 category)
S5F3/F4 Enable/Disable Alarm Send + AlarmAck
S5F5/F6 List Alarms Request / Data (active alarms tagged in ALCD)
S6F11/F12 Event Report Send (equipment-initiated CEID emission
with full report data) + EventReportAck
S7F3/F4 Process Program Send + ProcessProgramAck (7 values)
S7F5/F6 Process Program Request / Data
S7F19/F20 Current EPPD List Request / Data
S10F1/F2 Terminal Display Single (host->equipment) + TerminalAck
S10F3/F4 Terminal Display Single (equipment->host)
Demo apps:
apps/secs_server.cpp passive equipment. Populates the data model
with 3 SVIDs (ControlState, Clock,
EventsEnabled), 2 ECIDs, 3 CEIDs
(ControlStateChanged, AlarmSetEvent,
ProcessStarted), 2 alarms (Chiller Temp High
cat 4, Door Open cat 1), 2 recipes
(RECIPE-A, RECIPE-B), and 4 host commands
(START, STOP, PAUSE, FAULT). Emits S6F11 on
every control state transition + on START;
emits S5F1 + the AlarmSetEvent CEID on FAULT.
Pushes an S10F3 welcome message when the host
comes online.
apps/secs_client.cpp active host. Walks 17 steps: Establish ->
Online -> S1F11 SVID namelist -> S1F3 read ->
S2F29 EC namelist -> S2F13 read ->
S2F17 clock -> S2F33/S2F35/S2F37 dynamic
event subscription -> S2F41 START
(-> receives S6F11) -> S5F5 alarm list ->
S5F3 enable alarm 1 -> S2F41 FAULT
(-> receives S5F1 + S6F11) -> S7F19/S7F5
recipe list + body -> S10F1 terminal ->
S1F15 Offline -> Separate. Handles inbound
S6F11, S5F1, S10F3 primaries.
Testing:
tests/test_secs2.cpp codec round-trip for every format,
byte-layout assertions for known values,
truncation/trailing-byte rejection,
nested list round-trip, SML rendering
tests/test_hsms.cpp header byte layout, data + control
header round-trip, full frame round-
trip with length prefix, short-payload
rejection
tests/test_control_state.cpp every (state, event) pair in the E30
control state machine, including
AlreadyOnline / NotAccept rejections
and idempotent offline-while-offline
tests/test_data_model.cpp SVID/ECID/Alarm/Recipe CRUD, clock
format + parse, host command registry,
full event-report pipeline (define ->
link -> enable -> compose) with
every error path (InvalidVid,
UnknownCeid, UnknownRptid), alarm
set/clear with ALCD bit-7 semantics
tests/test_messages.cpp round-trip + byte-layout for every
builder/parser pair, including S6F11
event reports with mixed item types
Toolchain:
Dockerfile Ubuntu 24.04, g++-13, CMake, Ninja, libasio-dev
docker-compose.yml builder / tests / server / client services,
source bind-mounted, build artifacts in a
named volume so the host tree stays clean
CMakeLists.txt C++20, -Wall -Wextra -Wpedantic, standalone
Asio (ASIO_STANDALONE), doctest via FetchContent
Documentation:
README.md architecture, quick start, demo log
COMPLIANCE.md honest per-capability E5/E30/E37 audit with
spec section refs. Calls out what's implemented,
what's partial (Reject.req, Alarms missing F7/F8,
EC range validation, PP without verify, terminal
single-line only), and what's intentionally not
yet implemented (spooling, S9 error stream,
Documentation S1F19/F20+F21/F22, limits monitoring,
trace data collection, multi-block, material
movement). Does NOT claim "100% GEM-compliant" and
lists the work required to honestly make that claim.
This is Layer 0 + the start of Layer 1 from implementation_plan.md.
The transition-table-driven "spec-as-data" architecture (Layer 1
proper) is not yet implemented; the current code uses imperative
state machines that are structurally ready to be refactored onto
tables.
