Configuration

The event log is a set of variable values that are stored, with date and time, in the SD card of the device in the csv (comma separated value) format. Those values are recorded after the occurrence of events that may be of the following types: time, change of state or trigger. For each event log file, the file recording interval is configured and a Boolean variable, which is responsible for enabling or disabling the log through the program, is associated to it.

A text may be associated to each log configuration file, which will be presented together with the variables as soon as the upload of the event log is performed (see “text field configuration” section).

In the option menu of the event log, it is possible to carry out the following actions:

•	Add a new event log: in order to add a new event log, it is necessary to select the “New file” option from the folder “Event log”. For further information on how to configure the event log, see “Event log configuration” section.

•	Upload files SD card: after the download of the event log files configured for the equipment, it is possible to upload these files to view the events occurred. For more details, see “Upload files SD card” section.

•	Create log file: This functionality allows the user to create a log file within a defined period with the log files loaded in the project. For more details se ”Creation of log files” section.

In the event log configuration window, you configure: the recording interval of the event log file, the type of event log, the Boolean variable that enables the event log and the text to be displayed in the event log.

•	File interval: In the file interval field , the duration time of the recording of the data in a single file is configured. The options of this field are the following:

- Daily: The data will be recorded in a file a day. The recording of a new file begins whenever the day on the clock of the device changes. The file is recorded with a suffix containing the day, month and year on which its recording began.

- Monthly: The data will be recorded in a file a month. The recording of a new file begins whenever the month on the clock of the device changes. The file is recorded with a suffix containing the month and year in which its recording began.

- Annual: The data will be recorded in a file a year. The recording of a new file begins whenever the year on the clock of the device changes. The file is recorded with a suffix containing the year in which its recording began.

The event log is recorded in time intervals defined in the field “Period”. The value configured in the field "Period" must be a whole value greater than zero and smaller than 4294967295 s. The time unit can be selected from seconds, minutes or hours.

In the field “Variables” you select the variables that will be sampled in the configured period.

The event log is recorded after a change in the value of the selected variable. Only the value of the selected variable is recorded in the event log.

As in the "Time" event, the event log is recorded in time intervals defined in the field "Period", but only when the value of the configured variable in the field "Trigger" is within the limits selected in the variables of the "Upper limit" and "Lower limit" fields. The value configured in the "Period" field must be a whole value greater than zero and smaller than 4294967295 s. The time unit can be selected from seconds, minutes or hours.

In the field “Variables” you select the variables that will be sampled in the configured period.

In the “Text” field, it is possible to add a text to be shown together with the variables. This text will be added as soon as the event log file is loaded (through the upload of log files) to the WPS.

For the variable values to be inserted in any position of the text, markers will be added to the text which will be replaced by the variables.

According to the type of event log selected, the markers must be added the following way:

•	Time: the first variable of the list is represented by the marker {0}, the second by the marker {1} and thus successively.

•	Change of State: the only variable selected will be represented by the marker {0}.

•

Trigger: the "Trigger" variable is represented by the marker {0}, the "Upper limit" by the marker {1}, the “Lower limit” by the marker {2}, the first variable of the list by the marker {3}, the second by the marker {4} and thus successively. As an example, below is the configuration of an event log of the “Trigger” type and its log file.

There are two ways to upload the log files: upload all the project files or upload the files individually.

In order to upload all the log files configured in the project, it is necessary to select the folder “Event log” with the right button and select the option “Upload files SD card”.

In order to upload the files associated to only one event log configuration file, it is necessary to click the right button on the event log configuration file and select the option "Upload files SD card".

Attention: When uploading files, the previous files (with the same name) will be overwritten.

Through the log file creation tool, it is possible to create new event log files using the log files previously loaded on the project. Thus, it is possible to define the initial and final log interval and which log files must be used. In order to begin the creation of a new log file, it is necessary to click the right button of the mouse on the folder “Event log” and select the option “Create log file”. The configuration options for the new file are the following:

•	Initial interval: It determines the initial day and time of the file logs. If the “Unlimited” option is selected, there will not be a minimum value for the date.

•	Final interval: It determines the final day and time of the file logs. If the option “Unlimited” is selected, there will not be a maximum value for the date.

•	Files: It selects the log files that will be used to generate the new log file.
