What is the primary characteristic of Forced recording?

Forced recording is primarily characterized by its ability to log data whenever the value of a monitored parameter has changed outside of a defined range. This approach is particularly useful in scenarios where it is critical to capture any deviation from normal operating conditions, which could indicate potential issues or events that may require investigation. By focusing on changes that fall outside a specified range, forced recording ensures that significant events are captured, enabling better monitoring and analysis of the data.

For example, in a manufacturing environment, if the temperature of a process exceeds or falls below a predetermined threshold, forced recording would activate to log this occurrence, providing valuable insights into operational performance and potential anomalies.

In contrast, options related to recording at defined intervals or on tag value changes do not reflect the core function of forced recording, as they do not focus specifically on deviations from established ranges. Recording quality changes is also distinct, as it pertains to the reliability of the data rather than the value itself crossing set parameters.
