About this app

Monitor OPC UA servers on Android. Systematically manage on-site equipment and lines with a Workspace structure, and support real-time Pub/Sub reception.

Complete on-site work using OPC UA with just one smartphone.

This OPC UA monitoring app is designed for engineers and maintenance personnel in manufacturing and process sites. More than just a node viewer, it replicates on-site equipment, lines, and processes directly within the app using a unique hierarchical structure called Workspace, allowing for systematic management of multiple servers. In addition to traditional polling monitoring using OPC UA Client/Server, it also supports real-time reception using the latest OPC UA Pub/Sub (UDP/MQTT). It covers all on-site communication methods with a single device.

■ Workspace Management — Directly Representing the On-Site Structure in the App

Monitoring settings are managed in three layers: server, category, and monitor table. By switching between multiple workspaces, monitoring configurations for each line, equipment, and process can be saved and reused. Tags can be registered by directly referencing the address space with the Node Browser. Reading and writing registered values ​​and checking connection status can also be done in real time.
■ Real-time Monitoring — Understand the On-Site Status Locally

Periodically retrieves and displays tag values ​​from the OPC UA server. Supports writing values ​​to writable nodes. Continuous automatic updates are possible with the cyclic refresh function. Connection and reconnection management are handled automatically.

■ Event and Alarm Monitoring — Detect and Address Anomalies on the Spot

Supports OPC UA event subscriptions. Displays a real-time list of events, allowing for alarm status confirmation and approval within the application. Supports on-site anomaly response.

■ Pub/Sub Monitor — Real-time Reception and Dashboard Visualization

Receives OPC UA Pub/Sub data in real time from UADP (UDP multicast/unicast) and MQTT brokers. The received fields allow for flexible dashboard configuration using widgets such as numerical cards, gauges, bar graphs, sparklines, and event logs. Anomaly detection can also be performed by setting alarm thresholds for each field.


■ Historical Data and Method Calling — From Analysis to Operation in One Device

With OPC UA historical access support, you can refer to historical data for a specified period. It also supports the execution of OPC UA methods, allowing you to perform equipment operation tests and remote command execution directly from the app.

Recommended for:

* Engineers who want to mobile-check OPC UA-compatible PLCs, SCADA systems, and industrial equipment in the field.

* Maintenance personnel who want to centrally manage monitoring settings for multiple lines and equipment in a workspace.

* Those who want to receive and visualize real-time data from Pub/Sub-compatible equipment on their smartphones.

* Those who want to streamline on-site troubleshooting and equipment checks.
