The PLCnext Technology firmware 2019.6 brought us the real-time, task-synchronous DataLogger, which lets us record energy data or process steps. In addition, the embedded OPC UA Server supports Historical Access, so you can access all data recorded by the DataLogger at any time. Here's how to configure a set of data ports for use with OPC UA and then get access to the historical data.

This tutorial shows how to transfer a file to a PLCnext Control using an OPC UA client. For that we’re using the UaExpert client from Unified Automation, which you can download here.

OPC™ is a well-known, platform-independent interoperability standard for industrial automation, and its Unified Architecture (OPC UA) is an integral component of PLCnext Technology, which makes it compatible for integration into third-party systems. Read more about this standard here.

To reproduce this instruction, you have to connect to an OPC UA Server. Here's how to set up an OPC UA server connection with PLCnext Engineer in general, if you need help with that.
