With the concept of error code groups, you have the option of filtering the quality of measurement data using error codes when evaluating or checking data. For this purpose, user error codes can be (meaningfully) grouped together.

Important error code groups are for example:

▪the Valid group. This group contains all error codes that classify data as valid.

▪the Invalid group. This group contains all error codes that classify data as invalid.

▪the Manual validation group. This group contains all error codes that may be used for manual validations. These error codes can be selected in the graph and table in AquisNet DMO for various functions.

Refer to the Manual validation of measurement data section in ch. Display time series in the data collection center DMO.

▪AquisNet distinguishes between the categories System and User for error code groups. For example, groups under System, such as the Valid group, cannot be deleted because AquisNet accesses these groups in the course of validation:

▪For aggregations, the system accesses source time series and contained measured values with the error code valid.

▪The table and graph functions of the AquisNet DMO access the error code group manual validation to filter measured values.

▪Users can access error code groups via the reporting and evaluation functions in AquisNet.

▪However, depending on user rights, individual error codes can be added or removed.

To start the management of error code groups,

▪select the Time series > Error code > Manage error code groups menu item.

▪The Status Code Group Administration dialog opens:

▪In the tree view in the left window you can call up the error code groups. These are divided according to system and user. The system folder also contains those error code groups that are not deletable to ensure dependencies within the AquisNet system.

▪Under Status code groups, the selected error code group is displayed in the upper part of the right-hand window.

▪Below this, all error codes are listed with the description that have already been assigned to the called group.

▪Above the list display, further error codes can be selected via a selection list, which are taken over into the existing error code group after pressing the [Assign] button.
