OPCUA Monitor

Currently, as part of the initial release period, you can use the Pro version with all feature restrictions removed.

OPCUA Monitor is a mobile app that allows you to monitor OPC UA-compatible PLCs, SCADA systems, and industrial equipment from your smartphone or tablet.

It supports tag selection via Node Browser, list display via monitoring tables, and visualization via dashboards, allowing you to easily check equipment data on-site.

In addition to OPC UA Client/Server communication, it also supports real-time data reception via OPC UA Pub/Sub (UDP/MQTT).
