?What happens?
Older trace values are replaced by current values.
When does this behaviour occur?
As of PLC Designer V3.18, the trace buffer is by default limited to 10001 data points. When a trace is started, older trace values will be overwritten as of the 10001st value recorded.
Which products are affected?
PLC Designer V3.18 and higher
Short-term measures:
In order to record more than 10001 data points, you can manually increase the trace buffer size in the trace settings.
Evaluation/recommendations: As of PLC Designer V3.18, the trace buffer size has been limited. The trace buffer size can subsequently be increased.
