PVGuard® Product Feature Announcement - Service Log Feature

skytron energy is pleased to announce a new feature, the Service Log, which will be available with PVGuard® version 1.7.0. This product feature will be available starting Wednesday, April 10, 2013.

Comprehensive record-keeping for operation and maintenance

- The new service log feature provides you with chronological documentation about the operation and maintenance of your PV system.

- For traceability, the centrally maintained log, together with operator notes and details of the specific equipment involved, can be linked to service incidents such as alarms.

- The service log is closely integrated with the alarm management process and provides a simple and indispensable tool in helping you meet the necessary record keeping requirements for certification according to ISO 9001 and ISO 14001.

Brief description

The Service Log helps you to keep a record of service and maintenance activities on the plant, and to tie these records together with the data from the plant - measured data, alarms, errors and equipment status. Each plant has its own Service Log.


The log consists of a list of entries, each of which refers to a particular service incident (e.g. an inverter malfunction) or event (e.g. planned maintenance). An entry might include several notes (observations, telephone calls, details of site visits etc.), be linked to one or more pieces of equipment in the plant (inverter, combiner box, string etc.). It may be connected with one or more alarms, and can also be associated with other service log entries.

Viewing the Log

The Service Log for a power plant is opened by clicking on the Service Log entry for that plant in the view navigation. The view of the Service Log will open in a new window.


Each entry includes various filing information such as start date, a category, a user name, whether open or closed. Its main body is a tabbed box, letting you see the core details of the entry: the Notes, Alarms, associated Devices and Values, and any other Service Log entries with which this one is linked.

Navigating the Log

Since the list of entries might be long, there is a filter function at the top of the list. In addition to filtering, you can change the order in which the entries in the view are listed.


Another way of navigating the Service Log is provided by its Calendar function. Clicking on any date in the Calendar will cause the Service Log entries that were applicable on that date to be shown in the right hand pane of the Calendar. If the begin or end dates of the entry fall within the scope of the left-hand calendar pane, then the date in the list will be shown violet or green, matching the triangle on the date itself.

Editing the Log

You can add or edit log entries using the buttons at the bottom left. Double clicking on any entry in the log will also open the Edit Log Entry dialog. The upper section of this dialog contains the key information for cataloguing the log entry (these can then be used for filtering the Service Log entries).


- Subject: The title of the entry (any text). If a filter has been set for subject, then the default value of the subject will match the filter value; otherwise it will be taken from the value entered in the configuration settings.

- Category: Any value out of the pop-down list. You can also enter a completely new text entry here, which will then become available in the list. In addition, an auto-completion prompt will propose a possible value as soon as you start typing. If a filter has been set for category, then the default value of the category will match the filter value.

- User Sign: The creator (owner) of the entry. The default value will be taken from the value entered in the configuration settings.

- Begin: Start date/time of the event or incident. Defaults to the current time and date. Values in the future are also possible for planned activities.

- End:  End date/time of the event or incident. Functions similarly to Begin.

- State: Either Open or Closed. This is for supervision purposes. Mark finished tasks as Closed. In addition this state can be used as a filter.

- Ticket Number: Any text you choose. This field is designed for linking this entry with any other incident tracking systems you may have. The entry is stored for your reference and is not used for any other processing by PV Guard Client.

- Additional Fields1/2: Can be used for any data or metrics you wish. You can rename these fields by clicking on the field title or the pencil.



The main part of the dialog allows you to enter the specific details about the service event or incident, using a tabbed box with the headings described below:

- Notes: Any text concerning the entry. You can add as many individual notes as you wish.

- Alarms: Any alarms that are associated with the entry. You can either drag & drop alarms from the Alarms list in the view navigation or use the Add button to pop up a list of all alarms in the plant.

- Devices and Values: Shows the equipment or derived data associated with the log entry. You can link a device from the plant data explorer to the entry; either drag & drop plant data items into the list, or use the Add button to pop up a list from which you can select the devices and data channels.

- Log Entries: Sometimes a log entry will be associated in some way with another log entry; for example a service log entry about low power from a string might be later coupled with an entry concerning shade at the site.

Exporting the Log

You can export the log in one of many different formats by clicking on the Export button at the bottom right of the log. In addition to the existing export function to a text file, you now have the option of exporting the data in formats compatible with standard office-software, to assist you with further data processing.


You can also create reusable templates, selecting the data to be exported, the column order and the titles for the exported columns. A preview pane shows you the actual appearance of the data being exported, so you can easily tune your template settings to the desired export output.
