Error Status Management
Error Categories Description
The activation of an error, belonging to any category defined in an Error Profile, may depend on the presence/absence of data and/or source events. Profile error events can therefore be activated when specific conditions are detected on the data or when a device communicates to Aurora Vision the identification of a Source error event (that is a machine error identified by a device and sent to Aurora Vision, which will model it based on the device that sent it) that falls into one of the profile error categories.
The following are the categories of errors whose evaluation depends on specific conditions detected on the data (available only in English):
Category Error
Description
Default Status
Hierarchical Evaluation
NOTCOM
One or more devices have been correctly registered on Aurora Vision, but they haven’t communicated yet.
INFO
Plant Level
LOGCOM
Aurora Vision’s has not received any data from the inverter (or logger) for the configured timeout. Devices events will not be evaluated until communication with Aurora Vision is re-established.
HIGH
Logger/Device Level
DEVCOM
The device (e.g. meter, weather station, battery…) has not communicated with the inverter (or logger) for the configured timeout. Device events will not be evaluated until device communication is re-established.
MEDIUM
Device Level
PWROFF
The inverter has not produced power for the Elapsed Time duration, while irradiance remains above the Irradiance Threshold. If the plant does not have a functioning irradiance sensor, only the Elapsed Time will be used to trigger this event.
MEDIUM
Device Level
STROFF
A String Off State has been detected on this string. No current was produced by the string over a period of time when the average current output of all strings at the plant was above the threshold value.
MEDIUM
Device Level
STRLOW
A String Low State has been detected for the string. The current produced by the string was low, compared to the average current output of all strings at the plant, over a period of time when the average was above the threshold value.
MEDIUM
Device Level
SUBOFF
An OFF state has been detected for the sub-array. No current was produced over a period of time when the average current output, of all sub-arrays on the combiner, was above the threshold value.
MEDIUM
Device Level
PR-RNG
An Out-of-Range state has been detected. The Performance Ratio of the plant was detected out of range for a configured timeout.
LOW
Plant Level
All other categories of errors are evaluated based on the presence of source events directly communicated by the device to Aurora Vision. Regardless of the type of evaluation made, the activation of a profile error is always subject to the rules set for the specific error category defined in the error profile.
