Implicit Trend Logs
The implicit log is a change of value trend log which monitors the IO variable and records a new value if the variable exceeds the delta. Each log value is stored as a record in the trend log. The delta is automatically defined by the EcoStruxure Building Operation software depending on the measured unit of the device that is connected to the IO port.
The implicit log is not manually created as with the other trend logs in WorkStation.
The implicit trend log exists on all IO points. When a device is connected to an IO port, the implicit trend log is automatically configured and starts recording values.
