In today’s video, we are going to learn about Traces in CODESYS. This video shows you how to add Traces to an existing CODESYS application.
Traces are powerful debugging tools that let you create a graph of the values of application variables over time.
Traces are particularly useful for understanding what is happening in production systems that cannot be stopped, systems with real-time feedback like PID loops, and high-speed systems like labeling machines.
In CODESYS, a trace is an object that runs in the runtime on the PLC. While the trace is running, it records the values of a defined set of variables every PLC cycle.
The data captured by the trace is stored in a buffer with a fixed size in the PLC’s memory. Once the buffer is full, the oldest data in the buffer is overwritten by new data. This is what is called a ring buffer.
If you are logged in to the PLC through the CODESYS Development System, then you can monitor the trace’s data in real-time.
If you are not logged in to the PLC, the trace continues to collect data and this data can be uploaded to the CODESYS Development System for analysis later on.
Traces can be configured to have a trigger. When a trigger is detected, the trace records a pre-defined number of post-trigger samples and then stops recording data until the trigger is reset.
This is a very useful feature when you are trying to debug intermittent problems in a control system that are hard to monitor.
In this video, you will learn how to configure and utilize tracing in CODESYS for better debugging and monitoring of your applications.
We'll cover the process of adding a trace to your project, setting it up with specific tasks, and customizing its configuration, including triggers and sample rates.
You'll also find out how to add variables for detailed data analysis and how to download and monitor this data on a PLC.
