# wrps-demo-kit

A kit for building **demo automation use cases** on **Yokogawa CI Server** (SCADA)
and **OpenPLC Runtime** (soft PLC, in Docker) — with the **Waterloo Road Pump
Station (WRPS)** demo as its first worked example.

## The two systems

| Role | Host | Address |
|---|---|---|
| SCADA — Yokogawa CI Server | `yau-poc-cicore1` | `10.0.0.21` |
| PLC — OpenPLC Runtime container | `yau-sls-poc-lin001` | `10.0.0.17` |

**Architecture invariant:** OpenPLC Runtime is the Modbus TCP **server** (slave)
on port 502. CI Server is the Modbus **client** (master) and polls it. The
register map is the contract between the two sides.

## Layout

To be filled in as each part is brought across.
