Audit Trail

WideQuick Modular Framework includes a module for built in Audit Trail. The Audit Trail is intended to monitor control signals such as start/stop signals and setpoints but any variable, both internal and external can be added to the Audit Trail.

If a variable that is being tracked by the Audit Trail changes value, that change will be added to the Audit Trail log. The log contains information such as: the old value, the new value, which user that was logged in when the change occurred, a timestamp when change occurred as well as from which system, locally or via a remote client.

Adding/Removing variables to the Audit Trail

The Audit Trail module includes a workview to Add and Remove variables from the Audit Trail as well as a search function. By adding a variable you start tracking any changes to the variable and track this variable. Once you no longer want to track the variable you remove it and it will no longer be tracked.

Filter variables by name

The workview also allows users to filter the treeviews to select a subset of the DataStore that one whishes to add to or remove from the Audit Trail. By entering a filter of _IO in the leftmost of the treeviews all _io signals in the application gets filtered out into the list. These can then be selected and imported into the Audit Trial.

Adding multiple variables at once

Variables can be added at any depth of the DataStore hierarchy. For example, if one whishes to audit all signals in the entire Data Store. Select the DataStore node and press the > button in the user interface. Now, all of your variables are audited.

Note

It is not advisable to audit all variables in the Data Store. This function is, as mentioned above, for signals such as setpoints and start/stop signals that are important to track changes to a certain time and user.

The settings workview for the Audit Trail can be found in the main menu under "Loggar" --> "Loggar - Spårningslogg inställningar".

Audit Trail log

To view the Audited variables in your application the module has a workview with an Event List object and a filter. Here you can view historical events that have occurred in the application. You can also filter the view by object, timespan, recent events or users. In addition to this you can also sort the list on all columns in descending or ascending order.
