Testimonial
“ogamma Visual Logger for OPC helps us obtain industrial data and present it in Grafana. It has 2 features: you can historize time-series data from OPC UA Servers in InfluxDB, or present the data without historizing.
We have been connecting with ogamma directly to the PLC without using third-party software (like OPC servers). Usually, Grafana is used in IT to monitor server statuses, but the ogamma transforms it to OT. Now, we can link IT with OT. We have been using ogamma for months without any issues, and the program’s stability is great!”
Is OVL Right for You?
Our software ogamma Visual Logger for OPC can be used in all industries where storing and analyzing process control data is crucial for a smooth operation. For the best results, your data should be accessible over OPC UA using a wrapper app or without.
