Purpose of this note
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.
This note also shows how
Eurotherm’s unique instrument
‘Store & Forward’ functionality
operates

Application Note
Product
The nanodac recorder/controller provides combined recording and
control in a single ¼ DIN package.
Invensys Eurotherm has taken its extensive knowledge of secure
recording and accurate PID control and combined them in one small box
with a display that is so strikingly clear it belies its size.
The nanodac™ recorder/controller offers the ultimate in graphical
recording combined with PID control for a box of its size. The compact ¼
DIN panel mount unit offers four high accuracy universal inputs for data
recording and PID control. This secure data recording device with
accurate control is enhanced by a full colour, ¼ VGA display to bring a
crystal clear operator interface to even the smallest of machines.

Introduction
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.
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.
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.
• Automatic, data archiving to removable USB memory
stick (up to 8GB)
• Automatic, remote data archiving over Ethernet network

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.
‘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.
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 i s
Implicit.
