Rewrite src/ and tests/ project paths in docs, CLAUDE.md, README.md, and test-fixture READMEs to the new module-folder layout (Core/Server/Drivers/ Client/Tooling). References to retired v1 projects (Galaxy.Host/Proxy/Shared, the legacy monolithic test projects) are left untouched. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# `otopcua-ablegacy-cli` — AB Legacy (PCCC) test client
|
|
|
|
Ad-hoc probe / read / write / subscribe tool for SLC 500 / MicroLogix 1100 /
|
|
MicroLogix 1400 / PLC-5 devices, talking to the **same** `AbLegacyDriver` the
|
|
OtOpcUa server uses (libplctag PCCC back-end).
|
|
|
|
Third of four driver test-client CLIs. Shares `Driver.Cli.Common` with the
|
|
others.
|
|
|
|
## Build + run
|
|
|
|
```powershell
|
|
dotnet run --project src/Drivers/Cli/ZB.MOM.WW.OtOpcUa.Driver.AbLegacy.Cli -- --help
|
|
```
|
|
|
|
## Common flags
|
|
|
|
| Flag | Default | Purpose |
|
|
|---|---|---|
|
|
| `-g` / `--gateway` | **required** | Canonical `ab://host[:port]/cip-path` |
|
|
| `-P` / `--plc-type` | `Slc500` | Slc500 / MicroLogix / Plc5 / LogixPccc |
|
|
| `--timeout-ms` | `5000` | Per-operation timeout |
|
|
| `--verbose` | off | Serilog debug output |
|
|
|
|
Family ↔ CIP-path cheat sheet:
|
|
- **SLC 5/05 / PLC-5** — `1,0`
|
|
- **MicroLogix 1100 / 1400** — empty path (`ab://host/`) — they use direct EIP
|
|
with no backplane
|
|
- **LogixPccc** — `1,0` (Logix controller accessed via the PCCC compatibility
|
|
layer; rare)
|
|
|
|
## PCCC address primer
|
|
|
|
File letters imply data type; type flag still required so the CLI knows how to
|
|
parse your `--value`.
|
|
|
|
| File | Type | CLI `--type` |
|
|
|---|---|---|
|
|
| `N` | signed int16 | `Int` |
|
|
| `F` | float32 | `Float` |
|
|
| `B` | bit-packed (`B3:0/3` addresses bit 3 of word 0) | `Bit` |
|
|
| `L` | long int32 (SLC 5/05+ only) | `Long` |
|
|
| `A` | analog int (semantically like N) | `AnalogInt` |
|
|
| `ST` | ASCII string (82-byte + length header) | `String` |
|
|
| `T` | timer sub-element (`T4:0.ACC` / `.PRE` / `.EN` / `.DN`) | `TimerElement` |
|
|
| `C` | counter sub-element (`C5:0.ACC` / `.PRE` / `.CU` / `.CD` / `.DN`) | `CounterElement` |
|
|
| `R` | control sub-element (`R6:0.LEN` / `.POS` / `.EN` / `.DN` / `.ER`) | `ControlElement` |
|
|
|
|
## Commands
|
|
|
|
### `probe`
|
|
|
|
```powershell
|
|
# SLC 5/05 — default probe address N7:0
|
|
otopcua-ablegacy-cli probe -g ab://192.168.1.20/1,0
|
|
|
|
# MicroLogix 1100 — status file first word
|
|
otopcua-ablegacy-cli probe -g ab://192.168.1.30/ -P MicroLogix -a S:0
|
|
```
|
|
|
|
### `read`
|
|
|
|
```powershell
|
|
# Integer
|
|
otopcua-ablegacy-cli read -g ab://192.168.1.20/1,0 -a N7:10 -t Int
|
|
|
|
# Float
|
|
otopcua-ablegacy-cli read -g ab://192.168.1.20/1,0 -a F8:0 -t Float
|
|
|
|
# Bit-within-word
|
|
otopcua-ablegacy-cli read -g ab://192.168.1.20/1,0 -a B3:0/3 -t Bit
|
|
|
|
# Long (SLC 5/05+)
|
|
otopcua-ablegacy-cli read -g ab://192.168.1.20/1,0 -a L19:0 -t Long
|
|
|
|
# Timer ACC
|
|
otopcua-ablegacy-cli read -g ab://192.168.1.20/1,0 -a T4:0.ACC -t TimerElement
|
|
```
|
|
|
|
### `write`
|
|
|
|
```powershell
|
|
otopcua-ablegacy-cli write -g ab://192.168.1.20/1,0 -a N7:10 -t Int -v 42
|
|
otopcua-ablegacy-cli write -g ab://192.168.1.20/1,0 -a F8:0 -t Float -v 3.14
|
|
otopcua-ablegacy-cli write -g ab://192.168.1.20/1,0 -a B3:0/3 -t Bit -v on
|
|
```
|
|
|
|
Writes to timer / counter / control sub-elements land at the wire level but
|
|
the PLC's runtime semantics (EN/DN edge-triggering, preset reload) are
|
|
PLC-managed — use with caution.
|
|
|
|
### `subscribe`
|
|
|
|
```powershell
|
|
otopcua-ablegacy-cli subscribe -g ab://192.168.1.20/1,0 -a N7:10 -t Int -i 500
|
|
```
|
|
|
|
## Known caveat — ab_server upstream gap
|
|
|
|
The integration-fixture `ab_server` Docker container accepts TCP but its PCCC
|
|
dispatcher doesn't actually respond — see
|
|
[`tests/...AbLegacy.IntegrationTests/Docker/README.md`](../tests/Drivers/ZB.MOM.WW.OtOpcUa.Driver.AbLegacy.IntegrationTests/Docker/README.md).
|
|
Point `--gateway` at real hardware or an RSEmulate 500 box for end-to-end
|
|
wire-level validation. The CLI itself is correct regardless of which endpoint
|
|
you target.
