ogamma Visual Logger for OPC

Keep your data with ogamma Visual Logger for OPC,

an integration tool to collectstorevisualize and analyze industrial process control data.


Visual Logger Context Diagram

Key features:

  • Collects industrial process control data over OPC UA connections;
  • Using OPC DA to OPC UA wrapper can collect data from legacy industrial data sources too;
  • Or with an additional component ogamma Modbus OPC UA Server or Prosys OPC UA Modbus Server can collect data from any legacy device supporting Modbus protocol;
  • Supported storage destinations: traditional relational databases (PostgreSQL, Microsoft SQL Server, MySQL, SQLite) or modern time-series databases (InfluxDB, Timescale DB, Apache Kafka), or MQTT Broker (such as Eclipse Mosquitto, Microsoft Azure IoT Hub, AWS IoT Broker, Google Cloud IoT Core MQTT Bridge).
  • Stored data can be visualized using open source tool Grafana;
  • Stored data can be analyzed using queries;
  • Secure web-based configuration GUI with user authentication and authorization;
  • Unlimited duration of data storage;
  • Unlimited tags;
  • Millisecond resolution (with InfluxDb - microseconds resolution is supported too).
  • It can be scaled vertically and horizontally.
  • Runs on Linux, Windows or Raspberry Pi;
  • Supports Docker
  • Support for secured OPC UA communication modes and UserName/Password authentication.

Key differentiators:

  • Guaranteed to connect (specialized on OPC UA, modern standard IIoT communication protocol);
  • High efficient Store and Forward technique allows forwarding collected data to the destination database with minimal delay (less than a second), and can store data locally for days when the connection is lost;
  • Saves hardware and energy: written in modern C++, lightweight and high performant, low CPU and RAM usage at high throughputs. Single instance on embedded industrial or regular PC can serve all your needs in most cases: 100,000 variables changing every second handled easily;
  • Can be installed and runs in the server, desktop PC, or industrial embedded PC; or in Docker container;
  • Now available at Microsoft Azure Marketplace, and can be deployed as Azure IoT Edge Module;
  • Future proof (designed to scale and expand without limits, the load can be distributed on multiple nodes);
  • Quick commissioning (easy to configure using Web-based GUI);
  • Cloud-ready (can be deployed in premises or in the cloud);
  • Low-cost maintenance (easy deployment, upgrades, and maintenance backed by support for Docker);

Target Industries:

ogamma Visual Logger for OPC can be used in any industry where the storage of process control data and its analysis is required and when that data is accessible over OPC UA protocol (as well as classic OPC DA using additional wrapper application). Examples of customers who use it or expressed interest on it are (not in particular order):

  • Large beverages bottling plant, producing per one shift beverages enough to fill an Olympic Swimming Pool;
  • Automotive supplier of powertrain and brake components for leading auto manufacturers using it in Industry 4.0 project;
