Project description

tuivisu

Terminal UI for CODESYS PLCs — a TUI take on the WebVisu, readable and editable over SSH. Connects to the PLC's OPC UA server (the supported, documented channel; the WebVisu wire protocol itself is proprietary binary paint commands and deliberately not used).

Install

pipx install tuivisu

Run

tuivisu --url opc.tcp://<plc>:4840 --user <device-user> --password <pw>

Keys: q quit - arrow keys browse - type to edit a writable value.

PLC prerequisites

  • A Symbol Configuration object with Support OPC UA features enabled (Application → Add Object → Symbol Configuration), variables published, application downloaded.
  • A device user (or anonymous access explicitly allowed in the device's Communication Policy).

Development

py -m venv .venv
.venv/Scripts/pip install -e . --group dev
.venv/Scripts/python -m pytest -q
ruff check . && ruff format --check . && mypy src
