1 SAFETY NOTES
Warning: Any interruption of the protective conductor inside or outside the apparatus, or
disconnection of the protective earth terminal is likely to make the apparatus
dangerous under some fault conditions. Intentional interruption is prohibited.
Warning: Live sensors: The unit is designed to operate if the temperature sensor is connected
directly to an electrical heating element. It must be ensured that service personnel do
not touch connections to such inputs whilst the inputs are live. With live sensors, all
cables, connections and switches for connecting the sensor must be mains rated for
use in 240V Cat II.
Warning: Grounding the temperature sensor shield: Where it is common practice to replace
the temperature sensor whilst the instrument is live, it is recommended that the
shield of the temperature sensor be grounded to safety earth, as an additional
protection against electric shock.
Warning: The instrument must not be wired to a three-phase supply with an unearthed star
connection, because, under fault conditions, such a supply could rise above 240V
RMS with respect to ground, thus rendering the instrument unsafe.
Note: Safety requirements for permanently connected equipment state:
a. A switch or circuit breaker shall be included in the building installation.
b. It shall be in close proximity to the equipment and within easy reach of the operator.
c. It shall be marked as the disconnecting device for the equipment.
Note: Recommended external fuse ratings are: 2A Type T 250V.

1. This instrument is intended for industrial temperature and process control applications within the
requirements of the European directives on safety and EMC.
2. Installation may be carried out only by qualified personnel.
3. To prevent hands or metal tools coming into contact with parts that are electrically live the instrument
must be installed in an enclosure.
4. Where conductive pollution (e.g. condensation, carbon dust) is likely, adequate air conditioning/filtering/
sealing etc. must be installed in the enclosure.
5. The mains supply fuse within the power supply is not replaceable. If it is suspected that the fuse is faulty,
the manufacturer’s local service centre should be contacted for advice.
6. Whenever it is likely that protection has been impaired, the unit shall be made inoperative, and secured
against accidental operation. The manufacturer’s nearest service centre should be contacted for advice.
7. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment might be impaired.
8. The unit must be wired according to the instructions in this manual.
9. Before any other connection is made, the protective earth terminal shall be connected to a protective
conductor. The mains (supply voltage) wiring must be terminated in such a way that, should it slip, the
Earth wire would be the last wire to become disconnected. The protective earth terminal must remain
connected (even if the equipment is isolated from the mains supply), if any of the I/O circuits are
connected to hazardous voltages*.
The protective earth connection must always be the first to be connected and the last to be disconnected.
Wiring must comply with all local wiring regulations, e.g. in the UK, the latest IEEE wiring regulations
(BS7671) and in the USA, NEC class 1 wiring methods.
10. Signal and supply voltage wiring should be kept separate from one another. Where this is impractical,
shielded cables should be used for the signal wiring.
11.
The maximum continuous voltage applied between any of the following terminals must not exceed 240Vac.
1. Relay output to logic, dc or sensor input connections.
2. Any connection to ground.
The ac supply must not be connected to sensor input or low-level inputs or outputs.
12. Over temperature protection: A separate over-temperature protection unit (with an independent
temperature sensor) should be fitted to isolate the process heating circuit should a fault condition arise.
Alarm relays within the recorder/controller do not give protection under all fault conditions.
13. In order to allow the power supply capacitors to discharge to a safe voltage, the supply must be
disconnected at least two minutes before the instrument is removed from its sleeve. The touching of the
exposed electronics of an instrument which has been removed from its sleeve should be avoided.
14. Instrument labels may be cleaned using iso-propyl alcohol, or water or water-based products. A mild soap
solution may be used to clean other exterior surfaces.
* A full definition of ‘Hazardous’ voltages appears under ‘Hazardous live’ in BS EN61010. Briefly, under normal
operating conditions, hazardous voltages are defined as being > 30V RMS (42.2V peak) or > 60V dc.

1.1 USB DEVICE PRECAUTIONS
1. Precautions against electrostatic discharge should be taken when the instrument terminals are being
accessed. The USB and Ethernet connections are particularly vulnerable.
2. Ideally, the USB device should be plugged directly into the instrument, as the use of extension leads may
compromise the instrument’s ESD compliance. Where the instrument is being used in an electrically
‘noisy’ environment however, it is recommended that the user brings the USB socket to the front of the
panel using a short extension lead. This is because the USB may ‘lock up’ or reset in noisy environments
and the only means of recovery is to remove the device, then re-insert it. For memory sticks, EMC-related
failure during a write operation might cause corruption of the data held on the stick. For this reason, the
data on the memory stick should be backed up before insertion and checked after removal.
3. When using a USB extension cable, a high quality screened cable must be used. The total length of USB
cable between the device and the USB port must not exceed 3 metres (10 ft.).
4. Most barcode readers and keyboards are not designed for use in industrial EMC environments, and their
operation in such environments may result in impaired performance of the recorder/controller.
1.2 32-BIT RESOLUTION
Floating point values are stored in IEEE 32-bit single precision format. Values which require greater resolution
than is available in this format are rounded up or down.
1.3 SYMBOLS USED ON THE RECORDER LABELLING
One or more of the symbols below may appear as a part of the recorder labelling.

2 CYBERSECURITY
2.1 WHAT’S IN THIS CHAPTER
This chapter outlines some good practice approaches to cybersecurity as they relate to use of the nanodac
instrument, and draws attention to several nanodac features that could assist in implementing robust
cybersecurity.
2.2 INTRODUCTION
When utilising the nanodac in an industrial environment, it is important to take ‘cybersecurity’ into consideration:
in other words, the installation’s design should aim to prevent unauthorised and malicious access. This includes
both physical access (for instance via the front panel or HMI screens), and electronic access (via network
connections and digital communications).
2.3 SECURE NETWORK TOPOLOGIES AND GOOD PRACTICES
Overall design of a site network is outside the scope of this manual. The Cybersecurity Good Practices Guide,
Part Number HA032968 provides an overview of principles to consider. This is available from
www.eurotherm.co.uk.
Typically, an industrial controller such as the nanodac together with any associated HMI screens and controlled
devices should not be placed on a network with direct access to the public Internet. Rather, good practice
involves locating the devices on a fire-walled network segment, separated from the public Internet by a so-called
‘demilitarized zone’ (DMZ).
2.4 SECURITY FEATURES
The sections below draw attention to some of the cybersecurity features of the nanodac.
2.4.1 Principle of Secure by Default
Some of the digital communication features on the nanodac can provide greater convenience and ease-of-use
(particularly in regards to initial configuration), but also can potentially make the controller more vulnerable. For
this reason, some of these features are turned off by default. In particular, ID061 (the BACnet port is closed
unless the BACnet option is enabled).
2.4.2 HMI Access Level / Comms Config Mode
As described in Section 5.3.8, the nanodac device features tiered, password-restricted operator levels, so that
available functions and parameters can be restricted to appropriate personnel.
2.4.2.1 Logged Out Access Level
Logged out mode allows the user to select viewing mode, to view history, to view alarms, to toggle faceplate
cycling on and off, to send notes, to suspend/resume USB archiving and to access the login process.
2.4.2.2 Operator Access Level
In addition to the logged out features, Operator access level allows the user to acknowledge alarms, to edit
notes and to perform demand archive operations. By default, no password is required in order to enter Operator
level, but a password can be set either at Supervisor level or at Engineer level.
If the Auditor feature is enabled, the Operator user is disabled and instead replaced by the 25 User accounts.
2.4.2.3 Supervisor Access Level
In addition to the logged out features, this access level allows the user to view the recorder’s configuration, and
to edit some values (such as alarm thresholds).
2.4.2.4 Engineer Access Level
This allows full access to all areas of the recorder configuration.

HA030554
Issue 13 September 17
2.4.3 HMI Passwords
When entering passwords via the HMI, the following features help protect against unauthorised access:
• Each digit is obscured (replaced with an asterisk character) after entry, to help protect against an
unauthorized person seeing the password as it is typed in.
• Password entry is locked after a configurable number of invalid attempts (if Auditor option is enabled). If
this number of attempts is exceeded, the User account is disabled. This helps protect against “brute
force” attempts to guess the password.
• The controller records the number of successful and unsuccessful login attempts for each level of
password. This is recorded in the History. Regular auditing of this History is recommended, as a means
to help detect unauthorized access to the controller.
2.4.4 Ethernet security features
Ethernet connectivity is available on the nanodac. The following security features are specific to Ethernet:
2.4.4.1 Ethernet rate protection
One form of cyberattack is to try to make a controller process so much Ethernet traffic that this drains systems
resources and useful control is compromised. For this reason, the nanodac device includes an Ethernet rate
protection algorithm, which will detect excessive network activity and help to ensure the controller’s resources
are prioritized on the control strategy rather than the Ethernet. If this algorithm is activated, a message will be
entered into the History.
2.4.4.2 Broadcast Storm protection
A ‘broadcast storm’ is a condition which may be created by cyberattack: spurious network messages are sent
to devices which cause them to respond with further network messages, in a chain reaction that escalates until
the network is unable to transport normal traffic. The nanodac device includes a broadcast storm protection
algorithm, which will automatically detect this condition, stopping the controller from responding to the spurious
traffic. If this algorithm is activated, a message will be entered into the History.
2.4.5 Configuration backup and recovery
Using the iTools software, you can ‘clone’ a nanodac device, saving all its configuration and parameter settings
to a file. This can then be copied onto another controller, or used to restore the original controller’s settings.
Clone files are digitally signed using an SHA-256 cryptographic algorithm, meaning that if the file contents is
tampered with, it will not load back into a controller.
2.5 MEMORY INTEGRITY
When a nanodac device powers up, it automatically performs an integrity check on the contents of its internal
non-volatile memory devices. Additional periodic integrity checks are performed during normal runtime and
when non-volatile data is being written. If any integrity check detects a difference from what is expected, the
controller enters Standby mode and a message is displayed on then screen.

2.6 FIRMWARE
From time to time, to provide new functionality or address known issues, Eurotherm may make new versions of
the nanodac firmware available.
This firmware may be downloaded from the Eurotherm website, and transferred to a nanodac instrument in the
field, via a USB memory stick (or FTP server).
2.7 SUPPORTED PROTOCOLS AND THREAT MITIGATIONS
The nanodac supports the following protocols on Ethernet. For each protocol, a list of mitigations are provided.
As a general comment, the firewall is configured to block all ports except those required for installed/enabled
options.
2.7.1 FTP Client
An external FTP client can access the FTP server on the instrument. This FTP server has default remote
username & password for each of the default users, passwords can be modified. Additional users can be added
with configurable remote username and passwords.
To mitigate threats:
1. Physically protect access to subnet(s) in use.
2. Firewall to block TCP port 21.
3. It is recommended that user’s should change their passwords regularly, this could be done manually or by
using the password expiry feature.
2.7.2 FTP Server
Up to two external FTP servers can be configured. The nanodac will then connect to these servers as an FTP
client and push archive files to the servers.
Threat mitigation as for FTP Client.
2.7.3 ICMP (ping)
The nanodac will respond to a ping to aid network diagnostics.
To mitigate threats:
1. Physically protect access to subnet(s) in use.
2. Use a firewall to block ICMP / ping.
2.7.4 DHCP
The nanodac can allocate its IP address using DHCP; however this is typically set to fixed IP address allocation
by configuration. The DHCP server could be spoofed allocating an invalid IP address to the instrument.
To mitigate threats:
1. Use fixed IP address allocation.
2. Physically protect access to subnet(s) in use.
Caution: Non-Schneider Electric firmware
There is a potential risk that an attacker could upgrade a nanodac with non-
genuine firmware that contains malicious code. To mitigate this potential risk,
genuine nanodac firmware upgrade utility executables are always supplied digitally
signed with the publisher as Schneider Electric. Do not use a firmware upgrade
utility if it has not been signed by Schneider Electric.
Failure to follow these instructions can result in injury or equipment damage.

Issue 13 September 17
2.7.5 SNTP
The nanodac can support SNTP for network time synchronisation.
To mitigate threats:
1. Physically protect access to subnet(s) in use.
2. Firewall to block UDP port 123.
2.7.6 ModBus
The nanodac supports ModBus, which can be configured to act as Master via TCP and Slave via serial or TCP.
To mitigate threats:
1. Physically protect access to subnet (or serial cabling) in use.
2. Firewall to block TCP port 502 (or alternate non-standard port if so configured).
2.7.7 HTTP (Web Server)
To mitigate threats:
1. Physically protect access to subnet(s) in use.
2. Firewall to block TCP port 80.
2.7.8 UHH Navigator
To mitigate threats:
1. Physically protect access to subnet(s) in use.
2. Firewall to block TCP port 50010.
2.7.9 Ethernet IP
To mitigate threats:
1. Physically protect access to subnet in use.
2. Firewall to block TCP port 2222. This port is opened when Ethernet IP option is enabled.
2.7.10 BACnet
To mitigate threats:
1. Physically protect access to subnet in use.
2. Firewall to block UDP port 47808. This port is opened when BACnet option is enabled.
2.8 DECOMMISSIONING
When a nanodac instrument is at the end of its life and being decommissioned, Eurotherm advises reverting all
parameters to their default settings using the Engineer Password ‘reset’ or via iTools (see Section 6.1.6 and
Section 9 for instructions). This can help to protect against subsequent data and intellectual property theft if the
controller is then acquired by another party.

3 INTRODUCTION
This document describes the installation, operation and configuration of a paperless graphic recorder/
controller. The instrument comes, as standard, with four input channels and is equipped for secure archiving
via FTP transfer and/or to USB memory stick.
3.1 UNPACKING THE INSTRUMENT
The instrument is despatched in a special pack, designed to give adequate protection during transit. Should
the outer box show signs of damage, it should be opened immediately, and the contents examined. If there is
evidence of damage, the instrument should not be operated and the local representative contacted for
instructions. After the instrument has been removed from its packing, the packing should be examined to
ensure that all accessories and documentation have been removed. The packing should then be stored
against future transport requirements.

4.1.3 Removing the Instrument from its Sleeve
The instrument is designed to be removed from its sleeve from the front panel. However, if a USB memory stick
or the Ethernet cable is fitted then this must be removed first.
When the instrument is shipped from the factory it is fitted with two small red clips, one in the top side of the
sleeve and the other below. These are intended as a safeguard against removal of the instrument from its
sleeve when an Ethernet cable is fitted. These clips must also be removed, using a small screwdriver, before
the instrument can be taken out of its sleeve.
Ease the latching ears (Figure 2) outwards and pull the controller forward.
When plugging back in ensure that the latching ears click into place to maintain the panel sealing.
