The EXPORT sub-menu allows you to maintain an archive
of the processes completed through the following steps:
• Erase all records in internal memory or in the SD card
by touching the appropriate button.
• Copy all record files to a USB key by touching the
Copy all files key.
• Move (copy + delete) all record files on a USB key by
touching the Move all files key.
A level 1 or 2 user is required to delete or move files.
When an operation is performed, the state of progress is
displayed by a progressive horizontal bar. At the end of the
operation, the Operation completed message appears.
A USB key must be inserted in the controller before you
copy or move files. If the key is missing or is not properly
inserted, Wait USB appears under the USB bus symbol, to
the right.

to total memory is displayed graphically by a vertical bar to
the left of the box.

4.12.3.1. File format and data structure

The export file is a text file in CSV format (list of values
separated by ";"), which can be imported and read in an
Excel file.
The picture below shows how a generic file imported into
an Excel worksheet can appear.
The following are identified in the example worksheet:
• The instrument version (Version 1.0).
• The name of the program (Name) and operator ID (Idt).
• The segment name (Step name), its duration, any repe-
titions, applied program recipe, etc.
• The type of parameters tat are recorded in this exam-
ple: sequential sample number (Sample), date (Date),
time (Time), process value (AI_01_PT100_1) and
setpoint (PID_01_SP). Other samples could record a
higher number of parameters.
• The list of individual samplings, each of which is identi-
fied by date and time and shows the process tempera-
ture (PV) and that of the setpoint (SP).
• The list of events (Program_Run etc.) with date and
time when they occurred.
Files can be displayed in graph format as well as arranged
and display format adjusted using the DataLog Utility appli-
cation, distributed for free on the Gefran website.
