4. CONFIGURATION
Disk Full Alarm
Automatic alert with alarm (reported in the alarm list) when
the amount of free memory on internal disk or SD card, is
less than 5 MB.
All new DataLogger type recordings are disabled and Batch
reports will not be activated.
If Batch Reports are in progress, these will end normally,
but will not be restarted with the following RUN command.
Forced stop of recording
When the threshold of 3 MB is reached, active recordings
are also interrupted, while batch execution continues with-
out reporting.
4.12.2. TREND sub-menu
The TREND sub-menu shows, in graphic format, the time
trend for variables selected by the user (max 8 simultane-
ously, 24 in total). Up to 5000 samples are stored for each
record.
Use the
and
intervals to display in the page (1-8, 9-16 or 17-24).
A number of keys corresponding to the number of enabled
variables are displayed at the top. Each key:
•
enables and disables the graphic display relative to
variable that it represents;
•
displays the name of the monitored variable;
•
if you press without interruption for at least one second
the bottom of the scale of this curve appears (the
choice of the bottom of the scale may also be made
from the "Trend configuration" page)
The graph displays the time scale on the x axis and the
scale of recorded values on the ordinate y axis.
There is a bar that represents the entire sampling time be-
low the graph. The blue section indicates the sampling time
which is displayed in the graph. The displayed start and
end sampling times are shown below the x axis.
To scroll the entire sample back and forth, use the
and
keys and/or touch the bar.
If you press the

can scroll the track buttons.
4.12.2.1. Graph Scale
The scale of values (ordinate) is automatically determined
by the controller, taking the values set in the trend configu-
ration as extreme values set and dividing the interval by 5.
The time scale (abscissa) can be changed by the user with
48
buttons to select the variable
buttons on the 2850, you
the
and
keys. The length (in seconds) of each of
the 10 horizontal divisions of the grid is indicated below the
Grid time [s] label.
Vertical cursor
We may use the vertical cursor to identify the exact value of
the curve at a given instant in time. Date and time identified
by the green scrolling vertical line. The cursor may be made
to slide by touching the exact spot on the graph or by using
the
The cursor is always present.
4.12.2.2. Trend configuration
Touch the icon to set the trend
dow opens.
You must have level 2 permissions to set the trend and
proceed as follows:
1.
Set the sampling time, meaning the time interval with
which the controller stores the process variables. The
time varies from 1 to 60 seconds, in steps of 1 second.
The sampling time is the same for all variables.
To define the sampling time, touch the corresponding
field and enter the desired value using the virtual key-
board that appears.
2.
Enter the variables to be monitored. You can enter
analogue or digital values. The digital values will have a
fixed scale on two levels. The total number of variables
to be entered is 24. Use the
to select the insertion intervals (1-8, 9-16 or 17-24). For
more information on details of the variable selection
see the application example "7.1. Multi kiln control" on
page 105.
3.
Turn on the display of the variable using the check box
to the right of the variable name. To stop displaying,
just clear the check box (no need to delete the variable
from the list of variables to be controlled).
4.
Enter the minimum and maximum values of the scale
to be used for the variable. The setting is available only
for analogue values.
5.
Repeat steps 2 to 4 for each variable that you want to
enable or disable.
6.
Select the reference scale for the entire lot of variables.
7.
The Real and RetReal variables cannot be sampled.
8.
Reset the data on each individual curve with the Clear
function.
Touch the Graphs button to return to graph view.
