Application Note
Product
The nanodac recorder/controller provides combined recording and
control in a single ¼ DIN package.
This application note will
describe how to extract archived
data (both secure UHH and CSV
formats) from the nanodac
recorder/controller.
Data extraction of secure UHH
files will be described with an
example of how to set that up.
We will also provide links to
Eurotherm ‘Review’ and ‘Dream
Report’ software that can extract
the secure data for historical
trending and reporting
purposes.
Open CSV data extracted and
imported to Microsoft Excel will
be described with an example
spreadsheet shown.

Archiving Data from the nanodac Recorder/Controller
Introduction
PC tools to keep your data secure yet provide the
flexibility you need
The nanodac recorder is supported by PC based tools to
get your data in the way you need it. Review software acts
as an efficient and secure library for data from which charts
can be reviewed printed and exported to other PC
packages as required. Review maintains the integrity of
secure, binary files (UHH format) created by the nanodac
recorder and can be configured to pull data directly over
the network to provide a third data back up route.
The nanodac recorder/controller is ideal for use on any
application requiring up to four real universal inputs. An
additional fourteen inputs can also be written to over
communications effectively making an eighteen channel
data logger. Two PID control loops can be added for
applications such as ovens, furnaces, and chambers etc
where it is required to monitor temperatures and control
the loads.
The nanodac recorder can store your information in either
open CSV format or in a secure (UHH), check summed
format to protect data integrity.
•
In addition to live trending, a simple menu allows any
selected portion of the recorder history to be archived,
either to a ‘memory stick’ plugged into the USB port at the
rear of the recorder (Local Archiving) or to a computer or
server, by means of the FTP protocol (Remote Archiving).
The archived data remains in the flash (50MB)
memory of the instrument and can be reviewed
directly on the instrument display.

Secure Data Archiving
The archive period can be chosen
between the last hour, last day, last week,
last month, archive everything in the recorders
history or archive all files created since, or
updated since the last archive. The status of the
archive is displayed on the nanodac recorder/controller
which shows when data is being transferred or is complete.
The archive data includes actual values from real or comms
channels (PV), Alarm Messages, and Operator input
Messages all of which are accurately dated and time
stamped from the on-board real time clock.
Self Healing Data Archiving with ‘Store & Forward’
One of the many unique features of the Eurotherm archiving
strategies is to provide; Store & Forward’ functionality at the
instrument level.
Note: ‘Store & Forward’ is a
common functionality
included in any of the
Eurotherm electronic
archiving products. Other
than configuring the PC/
Server with the relevant
software loaded, there are
no other setup procedures
required – Data Security is
Implicit.

‘Store & Forward’ is a self healing, validated, data archiving
system that automatically stores data in the measuring
device during a communications
failure and then forwards this
to the configured PC/server
when communications have
been reinstated. This results
in secure electronic recording
with total data integrity.

nanodac Application Note
Application Example 1
This example works through the process of manually
transferring archived data to a PC in secure binary (UHH)
formats.
Alternatively Eurotherm instrumentation supporting Data
Recording and Archiving can be configured to push files to
a suitably named folder on an FTP Server. Once transferred
into the Review database graphical representations of the
process data can easily be created. Eurotherm Review
software is available in two versions, Review LITE, which is
supplied free with instrumentation that supports Data
Recording and Archiving and the enhanced FULL version
which provides the user with advanced features such as
Automatic print, and Auto-Archive.
Steps required to configure the archive:In Network
Archiving configure
the ‘Destination’ to
‘FTP Server‘and ‘File
Format’ to ’Binary
(UHH)’ *.
Typical Eurotherm Review Software Historical Trend Chart
and Review Feature List
It is then necessary
to define the
destination for the
data file. Enter the
IP address for the
PC to be used for
the primary server
and User and
Password assigned
by the administrator.
You can also
optionally add a
secondary server
that will be used if
for any reason the
primary is not
available.
FEATURE
Set up the PC as a server as described in the User Guide
HA030554 Appendix C. Connect the destination PC to the
instrument using the ethernet RJ45 connector.
Run Review as a Service
In ‘Demand Archiving’ select ‘Archive To’ as ‘FTP Server’ and
‘Archive’ to the required period, for example ‘Last Day’. The
data for the preceding day will be transferred as soon as
you scroll away from this entry.
The file produced will be a file containing binary data with
the extension .uhh. This is a secure format and requires
software such as Eurotherm ‘Review’ to interpret the data. It
is possible to produce both CSV and binary files by
configuring ‘File Format’ to ‘Both’.

nanodac Application Note
Archiving Data from the nanodac Recorder/Controller
Application Example 2
This example causes a CSV (Comma Separated Variable) file
to be produced to a memory stick fitted in the USB socket.
The .CSV file can be opened in a spreadsheet such as Excel.
To archive data:Go to ‘Demand
Archiving’ and in
‘Archive’ select the
period which you
wish to archive. You
can choose from
Last Hour, Day,
Week, Month or all
data in the
instrument memory.
Steps required to configure the archive:In Network
Archiving configure
‘File Format’ to ‘CSV’
(comma separated
variable).
Scroll away from this
parameter to transfer the data. The progress can be seen in
‘Status’.
The file produced is shown below and the path shown is
automatically produced.
(The folder under group1 shows information about the
device including its MAC address. When 100 files are
produced in this folder another later folder is produced).
Note: That MAC address is unique to the device and can be
used in determining the exact source of the original data.
Open the latest file to show the .CSV data in Excel
The format produced in Excel is fixed but sections can be
turned on or off in the Configuration menu (’ Network ’
Archiving) using the parameters shown in the spreadsheet
below.

nanodac Application Note
Application Example 3
The requirement is to record data to a memory stick leading
up to the occurrence of an event (say 1 hour). The recorded
data is to be shown in Excel.
This example causes a CSV file to be produced when an
event occurs. The event may be internal (triggered, for
example, by an alarm condition) or external (triggered by a
digital input). In this example an external event, connected
to Digital IO 1, triggers the production of a CSV file by
activating the parameter ‘Archive.Trigger located in the
Network function block.
It is first necessary to internally (soft) wire the output from
the digital input block to the trigger input of the Network
function block. This wire may be made through the front
panel buttons on the recorder using the wiring function.
Alternatively, use the graphical wiring editor in iTools as
shown in the diagram below.
When wired the parameter ‘Period’ appears. In this
parameter choose the period required for the data leading
up to the alarm or event eg ‘Last Hour’.
The event could be replaced by an alarm
condition by changing the DigIO function
block to an alarm function block.
This can be useful to interrogate the process
conditions which have led up to the alarm.
When the event occurs data is automatically transferred to
the memory stick. This can be seen in Demand Archiving
under Status ’ Complete ’ Transferring ’ Complete.
