2 DISPLAY LOG DATA
Which Log?
Xxxxxxxxxxx
Once in the second level, the system requests selection of the history to read.
The history log can be examined by event, i.e. parameters are recorded when an alarm triggers or an operating
cycle gets started, or by cyclic records, i.e. parameters are recorded at predefined intervals.
The last line shows the name of the history log, access to which is gained by pressing the Enter button.
Use the arrow up and arrow down buttons to go from an event-based log to a cyclic log, and vice versa.
3 DD-MM-YY HH:MM:SS
XXXXXXXXXXXXXX
XXXXXXXXXXX
1 (0)
When the event-based log is selected, access is gained to the third level. The above screen is an example of
this.
The first line shows the date and time of the event.
In the second and third lines, there is text that indicates the event. Since there is not much room for the
description and it only appears in English, the text includes the number of the corresponding alarm screen.
The fourth line shows whether the record refers to alarm activation or resetting. The example in the figure
shows status “1” which comes from “(0)”, so it refers to activation. Status “0” coming from “(1)” refers to alarm
resetting.
Click the arrow up on this screen to move on to the next event; click the arrow down to move back to the
previous event; and click the Enter button to move on to the next level where the values recorded at the time
of the event can be viewed.
4 DD-MM-YY HH:MM:SS
XXXXXXXXXXXXXX
XXXXXXXXXXX
The screens of the fourth level show the values recorded at the time of occurrence of the event displayed in
the relevant screen of the previous level.
The first line in the screen shows the same time and date as the previous screen, which refers to the time the
event was recorded.
The second and third lines describe the variable recorded with reference to the corresponding screen.
The last line shows the recorded value.
From this screen, all the values of the records made at the time of occurrence of the event to which they refer
can be scrolled using the up arrow and down arrow buttons.
A click on the "Enter" button gives access to the fifth level.

Log status: ENABLED
UP or DOWN: change
At the fifth level, which is common for both types of record, the records can be “ENABLED” or “DISABLED”
using the arrow buttons.
The records must be disabled when they need to be stopped to prevent loss of significant values, which may
be overwritten.
The second level gives access to the event-based history log and to the cyclic frequency-based history log. In
this case, a click on the Enter button from the second level gives access to the third level, a typical screen of
which is shown below.

UP : next record
DOWN : perv. record
ENTER : view data
