- Engineers working with industrial protocols and plant networks
- Worth noticing
- Production writes require typing the connection name, and the page says the check runs in the app backend rather than only in the interface.
Field notes
The listed workflows include MQTT topic trees with message counts and rates, Modbus polling with configurable rates, and OPC UA browsing with monitored items. For air-gapped use, the site describes activating a key by moving request and response files between machines; it also says the app runs without internet, an account, or telemetry.
