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 - Enter edit the selected value.
Values are live (OPC UA subscription) and update in place. Rows whose
Access shows rw * are editable scalars; Enter opens an input and confirms
before writing to the PLC. Which variables appear is whatever the project's
Symbol Configuration publishes — curate the set in the IDE, exactly like
binding a WebVisu to specific GVLs / program variables.
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).
