Add a Roadmap section to README.md and CLAUDE.md describing the two still-to-be-written lib/ tools (tro_export.py, scl_gen.py) that will turn the annotated CAD drawing into a JSON layout model and then into TIA-Portal-importable SCL, including the --skip-json shortcut.

# CLAUDE.md
|
||
|
||
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||
|
||
## Project purpose
|
||
|
||
`sps_skel` takes a mechanical layout (from project planning/sales) together with an
|
||
electrical layout (list of sensors, stoppers, switches, etc.) and generates a **skeleton
|
||
of Siemens SCL code** ("TRO" — Transfer Route Object — blocks for a conveyor/material-flow
|
||
control system) that can be imported directly into TIA Portal.
|
||
|
||
The repository has moved past pure analysis: `lib/` now holds working Python tooling that
|
||
derives a material-flow graph and a TRO list from a CSV export (ILS 2.0) and can annotate a
|
||
copy of the BricsCAD drawing with the result. What does **not** exist yet is the actual
|
||
SCL-skeleton generator — the step that would emit TIA-Portal-importable SCL from a JSON
|
||
layout model — nor the tool that derives that JSON model from the annotated drawing; see
|
||
"Roadmap" below for the planned two-tool pipeline that closes this gap. `tests/` and
|
||
`examples/` are still empty scaffolding (see "Standard Programm Template" below). What
|
||
exists today is:
|
||
|
||
- `bin/` — environment/venv management scripts, plus one `.bat`/`.sh` wrapper pair per CLI
|
||
tool in `lib/` (see "Environment scripts" below)
|
||
- `lib/*.py` — CLI tools and libraries that turn a CSV export + BricsCAD DXF into a
|
||
material-flow graph, a derived TRO list/diagram, and an annotated copy of the drawing.
|
||
See **`doc/Python_Scripts.md`** for what each script does and which switches it takes.
|
||
- `data/` — input CSV exports (gitignored, not committed)
|
||
- `cad/tro_types.lsp` — generated type list for the BricsCAD `TROEDIT` dialog (written by
|
||
`tro_annotate.py --emit-lisp`)
|
||
- `cfg/dxf_registration.json` — persisted, verified CSV↔DXF coordinate transform
|
||
- `doc/*.md` — analysis documents that reverse-engineer the SCL patterns and propose the
|
||
JSON schema / code-generation approach for the generator that's still to be written
|
||
|
||
Read `doc/` before writing any generator code — start with `doc/Python_Scripts.md` for the
|
||
existing tooling, then the domain-model documents below; together they contain the actual
|
||
domain model this project is meant to implement.
|
||
|
||
## Environment scripts (bin/)
|
||
|
||
Every script has a `.bat` (Windows) and `.sh` (Linux/macOS) pair. The four scripts below are
|
||
environment/venv management only — they never invoke a concrete Python script:
|
||
|
||
| Script | Purpose |
|
||
|---|---|
|
||
| `setenv.bat` / `source setenv.sh` | Sets `SPS_SKEL` (project root) and `SKEL_BIN/LIB/CFG/DATA/LOG/RESULTS/EXAMPLES/TESTS`; prepends `SKEL_LIB` to `PYTHONPATH`; creates missing folders |
|
||
| `install_py.bat` / `install_py.sh` | Calls `setenv`, creates `.venv` (`py -m venv` / `python3 -m venv`), installs `requirements.txt`. Aborts with a message if `.venv` already exists |
|
||
| `activate_venv.bat` / `activate_venv.sh` | Calls `setenv`, activates `.venv` (errors if missing — run `install_py` first) |
|
||
| `get_cmd.bat` / `get_cmd.sh` | Calls `setenv`, opens a new shell with the environment variables set |
|
||
|
||
**Convention:** every CLI tool added to `lib/` gets its own `.bat`/`.sh` wrapper pair in
|
||
`bin/`, named after the module (e.g. `lib/tro_flow.py` → `bin/tro_flow.bat` /
|
||
`bin/tro_flow.sh`). Each wrapper calls `setenv`, activates `.venv` if present, then runs the
|
||
module with `py`/`python3 "%*"`/`"$@"`. This supersedes the old "env-only" rule — see
|
||
`bin/material_flow.bat`, `bin/tro_flow.bat`, `bin/tro_annotate.bat` (+ `.sh`) for the current
|
||
pattern, and `doc/Python_Scripts.md` for what each tool does and which switches it takes.
|
||
|
||
Typical workflow on Windows:
|
||
|
||
```
|
||
bin\install_py.bat # one-time: create venv + pip install
|
||
bin\activate_venv.bat # each session: activate venv + show versions
|
||
```
|
||
|
||
Linux/macOS equivalents must be **sourced**, not executed:
|
||
|
||
```
|
||
bash bin/install_py.sh
|
||
source bin/activate_venv.sh
|
||
```
|
||
|
||
Requires Python 3.10+. `requirements.txt` pins `pydantic>=2.0.0` (used throughout `lib/`
|
||
for validated models) and `ezdxf>=1.4.0` (DXF read/write, `tro_annotate.py` only); `pytest`
|
||
is commented out as not yet needed.
|
||
|
||
There is no build/lint/test command configured yet — `tests/` is empty and no test
|
||
runner or linter is set up. Once tests exist, use `pytest` (already anticipated in
|
||
`requirements.txt`, just commented out) and set `PYTHONPATH` via `bin/setenv` first so
|
||
imports resolve against `lib/`.
|
||
|
||
## Domain model (from doc/)
|
||
|
||
The target system is a Siemens TIA Portal / SCL project for automated conveyor/carrier
|
||
routing, modeled around **TRO** (Transfer Route Object) blocks. Key documents, read in
|
||
this order for onboarding:
|
||
|
||
0. **`doc/Python_Scripts.md`** — the existing CLI tooling (`lib/material_flow.py`,
|
||
`lib/tro_flow.py`, `lib/tro_annotate.py`, plus the `lib/tro_catalog.py` and
|
||
`lib/dxf_registration.py` libraries they share): what each script does, its switches,
|
||
inputs/outputs. This is working code, not a proposal — read it before touching `lib/`.
|
||
1. **`doc/HundM/Json_Layout-Konzept.md`** — the core proposal: a JSON file as single source
|
||
of truth (`plc`, `controlUnits`, `sensors[]`, `conveyors[]`, `tros[]`, `loadingBooms[]`,
|
||
`emptyCarrBuffers[]`, `routing`, `jamAreas[]`, `scanners[]`, `connections[]`,
|
||
`destinations[]`) from which the repetitive, per-topology SCL code in `FB_Main`,
|
||
`FB_CallSensors`, `FC_Direction`, `FC_Call_Jams` would be generated.
|
||
2. **`doc/TRO_Typen.md`** — catalogs all 10 TRO function-block types actually found across
|
||
the 5 reference controllers (UH01–UH05) and shows that 9 of them are additive
|
||
combinations of one base type (`1Sep` = one separator/stopper) plus reusable
|
||
sub-blocks (`FB_ILS_STRO_Sep`, `FB_ILS_STRO_Switch`, `FB_ILS_STRO_Vario`,
|
||
`FB_BarcodeReaderCognex`, `FB_CarrAccumulate1Sep`). Only `LoadingBoom` is structurally
|
||
independent. `lib/tro_catalog.py` is the executable form of this catalog (name, FB
|
||
block, sub-components, color, CAD symbol per type).
|
||
3. **`doc/HundM/EA-Listen-Analyse.md`** — analyzes the raw I/O list Excel exports
|
||
(`*_EA.xlsx`/`*_TIA.xlsx`/`*_WSCAD.xlsx`) and companion position/cabling JSON exports,
|
||
and what can vs. cannot be auto-derived from them (signal naming prefixes `BG/SF/DI/BP`
|
||
for inputs, `MB/MA/QA/DQ/FC/PF` for outputs; topology/timing/customCode cannot be
|
||
derived from I/O lists alone — those must come from the JSON model or CAD symbol).
|
||
4. **`doc/HundM/BricsCAD_TRO_Symbol.md`** — proposes a BricsCAD block symbol whose
|
||
attributes feed the JSON `tros[]` entries; documents which fields are captured on the
|
||
symbol vs. derived from drawing topology or type-based timing defaults.
|
||
`lib/tro_annotate.py` implements a first version of this (marker blocks with `ID`/
|
||
`TYPE`/`FB_BLOCK` attributes), plus the `TROEDIT` BricsCAD dialog (`cad/tro_types.lsp`,
|
||
generated by `tro_annotate.py --emit-lisp`).
|
||
5. **`doc/HundM/SCL_Analyse_Standardisierung.md`** — cross-controller duplication analysis;
|
||
identifies ~22 blocks duplicated identically across all 5 controllers (candidates for
|
||
a shared library) and flags "version chaos" areas (e.g. `FB_StockRemovalBLKModul*`
|
||
variants) that should NOT be naively merged.
|
||
6. **`doc/HundM/suggestion.md`** — a follow-up proposal to collapse the 7 `FB_ILS_MTRO_*`
|
||
variants into a single `FB_ILS_MTRO` block driven by an array/config descriptor
|
||
instead of hand-duplicated numbered members (`...1`, `...2`, `Dir1..Dir4`). References
|
||
a not-yet-written `lib/create_skel.py` (`guess_fbtype()`) as the intended generator
|
||
entry point — this is still the planned shape of the SCL-emitting generator itself;
|
||
the current `lib/` tooling derives TROs from a layout but does not yet emit SCL.
|
||
7. **`doc/500573_Mubea/TRO_Identifikation_500573.md`** — the derivation rules
|
||
`lib/tro_flow.py` implements: how to infer a TRO's type from its separator's host
|
||
object (Gefällestrecke/Strecke/Kreisel) when no I/O list or `FB_Main` exists yet.
|
||
8. **`doc/TRO_Katalog/TRO_Katalog.md`** — central image/concept catalog per TRO type
|
||
(schematic, real layout image, SCL template, JSON example, CAD symbol attributes);
|
||
its generated images come from `doc/TRO_Katalog/tro_graphs/gen_tro_graphs.py`
|
||
(doc-tooling, not part of the generator — see `doc/Python_Scripts.md` §8) built from
|
||
`doc/TRO_Katalog/connect.ini`.
|
||
|
||
### Used libraries (referenced but not vendored)
|
||
|
||
Most `FB_ILS_MTRO_*` types exist in this repo **only as `.liblink`** references to an
|
||
external `ILSLib` library — the actual FB source is not in this Git repo.
|
||
`doc/TRO_Katalog/scl_templates/*.scl` contains the real **call-site/instantiation code**
|
||
(parametrization in `FB_Main`) for those types, not the FB body. Only a few types have
|
||
local, fully-vendored SCL source (`FB_ILS_MTRO_Vario_workStation`, `FB_EmptyCarrBuffer`,
|
||
`FB_LoadingBoom_INBOUND`, `FB_ILS_MTRO_2Sep1Swi` — the last one unused/orphaned). Treat
|
||
`doc/TRO_Katalog/scl_templates/*.scl` as **read-only reference material** for pattern
|
||
extraction, not code to execute or modify.
|
||
|
||
## Roadmap: DXF → JSON → SCL (planned, not implemented)
|
||
|
||
`tro_annotate.py` is where the current pipeline stops today: the user can keep hand-editing
|
||
the annotated DXF copy afterwards (via the BricsCAD `TRO_INSERT`/`TRO_EDIT` commands, see
|
||
`doc/HundM/BricsCAD_TRO_Symbol.md`) — moving TROs, adding new ones, or changing a type. Two
|
||
more `lib/` tools are planned to carry that drawing the rest of the way to importable SCL:
|
||
|
||
1. **`lib/tro_export.py`** (planned) — reads the (possibly hand-edited) annotated DXF plus
|
||
the CSV export and derives the JSON layout file described in
|
||
`doc/HundM/Json_Layout-Konzept.md` (`plc`, `controlUnits`, `sensors[]`, `conveyors[]`,
|
||
`tros[]`, `loadingBooms[]`, `emptyCarrBuffers[]`, `routing`, `jamAreas[]`, `scanners[]`,
|
||
`connections[]`, `destinations[]`). Per-TRO timing (`trailingTime`, `handlingTime`,
|
||
`senFree`, `senWait`, `jamTime`, ...) comes from the type-based default table in
|
||
`doc/TRO_Typen.md` unless the CAD symbol carries an `OVERRIDE_TIMING_JSON` value (see
|
||
`doc/HundM/BricsCAD_TRO_Symbol.md`), in which case the override wins. The resulting JSON
|
||
file is meant to be hand-edited afterwards — that's the intended place to tweak defaults
|
||
or individual timings before code generation.
|
||
2. **`lib/scl_gen.py`** (planned) — reads the JSON layout file and emits the `.scl` files
|
||
(`FB_Main`, `FB_CallSensors`, `FC_Direction`, `FC_Call_Jams` per controller) ready for
|
||
TIA Portal import. Takes a `--skip-json` switch for the case where no manual JSON edits
|
||
are needed: it then reads the DXF + CSV directly (running the same derivation as
|
||
`tro_export.py` internally) and emits SCL immediately, without writing or reading an
|
||
intermediate JSON file.
|
||
|
||
Both tools follow the existing `lib/` conventions once written: a `bin/<name>.bat`/`.sh`
|
||
wrapper pair (see "Environment scripts" above) and a switches/outputs section in
|
||
`doc/Python_Scripts.md`. Note this is a separate concept from the `create_skel.py` /
|
||
`guess_fbtype()` generator sketched in `doc/HundM/suggestion.md` and
|
||
`doc/HundM/Json_Layout-Konzept.md` §14.5 — that one is designed to derive its skeleton JSON
|
||
from HundM's Excel I/O-list exports (`*_TIA.xlsx`, `*_positions.json`, ...), a different
|
||
input source than this repo's CSV+DXF pipeline. The JSON *schema* it targets is the same
|
||
(`doc/HundM/Json_Layout-Konzept.md`); only the derivation source differs.
|
||
|
||
## Standard Programm Template
|
||
|
||
This project follows the user's standard Python project scaffold convention:
|
||
|
||
```
|
||
sps_skel/
|
||
bin/ environment scripts, plus one .bat/.sh wrapper pair per lib/ CLI tool
|
||
cad/ generated BricsCAD LISP support (tro_types.lsp) for the TROEDIT dialog
|
||
cfg/ config files (INI/JSON); dxf_registration.json holds the persisted,
|
||
verified CSV<->DXF coordinate transform
|
||
data/ input CSV exports — gitignored, not committed
|
||
doc/ documentation — see doc/Python_Scripts.md for the CLI tools, plus the
|
||
domain-model documents listed above
|
||
examples/ example files — empty for now
|
||
lib/ Python source, importable via SKEL_LIB on PYTHONPATH — CLI tools and
|
||
libraries that derive material flow / TRO lists / CAD annotations from a
|
||
layout (see doc/Python_Scripts.md); the JSON-driven SCL generator itself
|
||
is not yet written
|
||
log/ gitignored
|
||
results/ gitignored — CLI tool output (.dot/.svg/.md/.dxf)
|
||
tests/ unit tests — empty for now
|
||
```
|
||
|
||
When adding the SCL generator, put it under `lib/` (importable via `SKEL_LIB` on
|
||
`PYTHONPATH`), add a `bin/<name>.bat`/`.sh` wrapper pair for it following the pattern of
|
||
`bin/tro_flow.bat`/`.sh` (see "Environment scripts" above), document its switches in
|
||
`doc/Python_Scripts.md`, and add tests under `tests/`.
