1 Product description
1.1 Introduction to the SKF Enlight Collect IMx-1 system
The overall architecture of the SKF Enlight Collect IMx-1 System can be illustrated by
the figure below.
Figure 1 SKF Enlight Collect IMx-1 System architecture –single gateway, one sensor shown
The system consisting of sensors, gateways, analysis and visualisation software and
a mobile application, the Enlight Collect Manager app, provides the opportunity for a
completely wireless architecture at the machinery being monitored.
One gateway and its associated wireless sensors form a communication network.
This may also include relay nodes, essentially sensors that have their measurements
disabled and that are used to support/extend the wireless mesh. A system consists of
the analysis and visualisation software and at least one gateway, although in most
systems, multiple gateways are anticipated. Different gateways might typically be
applied to different machine groups, production processes or physical plant areas.
On a periodic basis, the sensors measure the vibration and temperature of the
monitored machinery, pre-process the vibration signals and transmit all the resulting
data to the gateway. This is then forwarded to the analysis and visualisation software
where the final analysis is performed, and historical data is stored. The analysis and

visualisation software, SKF @ptitude Observer, can be installed on a local server at
the customer location or as a cloud solution.
1.2 System considerations and architectures
The sensor –gateway interface is a radio system for wireless mesh networks with a
low power consumption and support for over-the-air (OTA) firmware updates. It is
specifically designed to enable reliable communication in congested wireless
environments and can identify and adapt to changes it has detected. The radio
operates on the 2.4 GHz ISM (Industrial, Scientific, Medical) band.
Whilst the wireless range will be dependent on plant topology, being a mesh system,
relay nodes can be deployed or outlying sensors can rely on the sensor mesh rather
than direct sensor/gateway communication. This assists in industrial environments
where a line of sight connection may be restricted or where sensors are situated
across wider areas. As a minimum, the system has been designed to support a
topography where there are up to 10 node jumps from the gateway to the furthest
sensor in the mesh. To provide the sensor mesh with opportunities to adapt, aim for
an installation where each node has at least 3 other nodes within wireless range.
This sensor radio interface can operate concurrently with other activity in the same
band, including the radios for:
•Wi-Fi, a network/@ptitude Observer connection, option
•WPAN IEEE 802.15.1 for app interfacing: on a mobile phone, this is
known as Bluetooth®.
The gateway –software network connection can be chosen to suit specific site
requirements. A hard-wired Ethernet connection is the default, but Wi-Fi*is also
provided as a wire free alternative.
Communication between the gateway/sensor and mobile app for on-site sensor and
gateway commissioning, is achieved over the phone’s Bluetooth Low Energy, radio
connection.
For the sensor commissioning, it is first woken from flight mode using the app and
the phone to provide an NFC (Near Field Communication) ‘tap’. For the gateway, the
app supports an initial identification by QR code rather than manual gateway
selection from the Bluetooth scan results. Using the QR code identification method
for the gateway is particularly useful where multiple gateways may be identified on
the scan.
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

*Important Note: for local, on premise, @ptitude Observer installations Wi-Fi access
to the server is required so that a connection to the app can be established during
commissioning and maintenance. This connection can be just temporary and can
precede the commissioning work but is required irrespective of whether Wi-Fi is used
for the gateway network connection.
1.3 SKF Enlight Collect IMx-1 wireless sensors
The IMx-1 sensor (CMWA 6100) is aimed at the monitoring of fixed plant and
equipment. This battery powered, wireless sensor facilitates an Enlight Collect online
system replacing traditional periodic monitoring using portable equipment. It supports
the following measurements:
•Acceleration
•Velocity
•Enveloping
•Temperature
The sensor has a female mounting thread and can be fixed to the measuring point
via a threaded mounting stud or an adapter disc with stud, where the disc is
adhesively bonded to the machine.
1.4 SKF Enlight Collect gateway
The Enlight Collect Gateway (CMWA 6600) is placed in the production/industrial
environment, somewhere central to its associated sensors and in a location where
power and any required network connections can be made available to it. Each
gateway can manage multiple sensors: testing is currently limited to 20 sensors
across a maximum of 10 functional locations.
Where possible choose a gateway location that maximises the number of IMx-1
sensors that have a direct line of sight, with it. As support for external antennas is not
yet implemented do not enclose the gateway inside a further/outer enclosure that
would block the radio signals.
Note: gateways must be associated with their own set of sensors, a particular sensor
can only communicate with one gateway.
1.4.1 Connections and interfaces
The gateway is housed in an IP rated enclosure and has built-in antenna for Wi-Fi
and sensor mesh communications. The lower panel is the only area normally
accessible to the user and conceals IP rated connectors for all wired connections. A
view of the gateway with its various features and connections highlighted, is shown
below:

To access the connector area, unscrew the two Torx T10 screws on the lower edge
of the cover at the locations circled in the image above. Once this cover is removed,
four M12 connectors and one blanking plug are accessible:
1. Connector for dual speed inputs with transducer power (future use)
2. Connector for Ethernet link 2 (future use)
3. Connector for Ethernet link 1 and PoE
4. Connector for DC power input to the gateway
5. Access to SIM card holder (future use)
6. Gateway LED indicators
7. Connectors for external antenna: LTE x2, Mesh and Wi-Fi (future use)
Important note: Only the two connectors listed in bold above are usable, the
remainder relate to potential future functionality and are not currently supported.
Normally, no user access is needed to the gateway internals, all user connections
are made available externally at these interfaces.
1.4.2 LED indicators
The upper front panel of the gateway has positions for two, multi-colour, LED status
indicators –item 6 figure 2 above:

1.4.3 Data and event time stamping
Each gateway has a backup power capacitor which will maintain the Real Time Clock
(RTC) setting for approximately one week if the device is disconnected from power.
1.4.4 Data acquisition scheduling
The gateway is configured with four data acquisition schedules by way of Interval
and Interval alarm settings for both the Scheduled Trend Storage and Scheduled
Dynamic Data Storage. These schedules are common to sensors associated with a
machine and are set in @ptitude Observer at the Machine Properties level, Enlight
Collect IMx-1 System tab, see 2.4.1.
Notes on scheduling and measurements:
To ensure sensor network stability, the gateway is a master to the multiple sensor
‘slaves’ so a sensor can never initiate a measurement nor the transfer of data to the
gateway. Measurement and measurement data transfer is always at the request of
the gateway and these requests are sent sequentially to the different sensors.
After a start-up the gateway will wait for the configured time period before requesting
the ‘first’ sensor measurements. If changes are made to the schedule and these
changes are synchronised, any ongoing measurement cycle for the machine will
complete and then the new schedule will be implemented. This process will take
account of when the last measurement cycle ran so, after a synchronisation, the wait
for ‘first’ data will usually be less than the scheduled period.
In addition, whenever a sensor receives a new configuration, for example and
including its initial configuration during commissioning, the gateway will then request
that the sensor make a set of overall measurements, without waiting for the
configured time period. This ensures a timelier receipt of data during commissioning
rather than having to wait for the scheduled time to elapse.
When the gateway first detects an alarm state change from a sensor on the machine,
that will trigger requests for representative TWF data from all sensors on that
machine.

SKF Enlight Collect IMx-1 System
User Manual
Revision A
If configured schedules cannot be met, all sensors will still be measured, but at the
best achievable rate and with some slippage from the configured schedule.
Sensors that cannot be reached are assumed to be now, in a normal, non-alarm
state.
1.4.5 Local data storage
The gateway will buffer measurement/event data until it is able to be transferred to
the host system/software. Initially this buffering is in volatile RAM but if the data has
not been transferred in 5 minutes then that data is transferred to non-volatile
memory. This prevents significant data loss if the gateway loses power. The design
aims to safeguard at least a week of data in this way.
1.5 SKF Enlight Collect Manager –Android app
The SKF Enlight Collect Manager app is available for Android devices and is used to
perform on-site system maintenance, commissioning, etc. The Android device being
used must support:
•NFC –Near Field Communications
•be at Android version 7 or later
•have Bluetooth Low Energy version 4.2 or later
Note that as NFC and Bluetooth also rely on device hardware an update of the
Android operating system is, in-itself, likely insufficient.
A user logging into the app must use User name and Password credentials
appropriate to the @ptitude Observer database for the particular plant or area being
commissioned. As this requires the app to be pre-configured with the details of the
Observer instance that applies, a separate local access “Enter system settings”is
available to set these details:

As can be seen above, for each Observer Monitor instance a friendly informative
Name, an Address and a Port number are entered. As these settings are critical for
connection to the Observer Monitor, ensure that they correctly reflect the required
instance otherwise a log-in failure can be expected. Note that where communication
to Monitor will be across public networks, the address entered here should be the
external facing or public IP address for the Monitor server.
Multiple connections can be configured, but only one can be active at any time.
Ensure the required connection is selected by the radio button and ‘Save Selected’
has been actioned.
Referring back to Figure 3a, it can be seen that when the connection details for at
least one Monitor instance have been configured, the name of the active/selected
Monitor server instance is shown on the opening screen of the app, just above ‘Enter
system settings’.
1.5.1 Security
Use of TLS security for app communications with the gateway is automatic.
To support secured/encrypted connections to and from the app, certificates will be
installed on the Android device. This is automatic but an Android user can generally
check which certificates are loaded by navigating to:
Settings > Security > Encryption & Credentials > Credential storage

2 Integration with SKF @ptitude Observer
2.1 @ptitude Observer overview and prerequisites
Before starting pre-commissioning, a suitably licensed version 12.0 or later, @ptitude
Monitor/Observer, must be installed and functioning. It should have an appropriate
database available with machines created and their operating speeds set. Sub-
machines must then be defined ready for IMx-1 sensor placement. As with other
types of measurement points and hardware, the @ptitude Observer system log will
capture all configuration changes that users make.
General guidance on using @ptitude Observer software can be found in its user
manual, part number 32170900. For specific content related to the SKF Enlight
Collect IMx-1 System, this must be revision R or later.
2.1.1 Communication with the SKF Enlight Collect IMx-1 system
Like the app, the gateway uses an MQTT login so that only devices with the correct
rights can connect, so enable an MQTT service (Message Queuing Telemetry
Transport) by the tick box on the Database > Options > Monitor service tab:
Figure 5 Monitor service tab –MQTT Service
Three configuration parameters then apply:
•Listening interface: This is the network interface that Monitor will listen on for
MQTT messages. The interface is specified by its IP-address, noting that the

address entered here should always be the internal or private IP address for
the Monitor server and not its public IP address.
•Port: The port Monitor will listen to. By default, this is set to the standard, non-
TLS, MQTT port 1883. Ensure that incoming MQTT, TCP connections to this
port are not blocked by a firewall.
2.1.2 Users and security role rights
All personnel undertaking on-site installation and commissioning tasks using the app
must be added as @ptitude Observer users with appropriate rights. There is a
specific, single, right that applies to IMx-1 System access and the Enlight Collect
Manager app.
Some pre-configured security roles, Administrator, Maintenance Manager and
Machine Operator Level 2 have this right. These roles differ significantly however in
their overall scope. For example, the role “Machine Operator Level 2” has otherwise
very limited rights so would not allow the user to perform IMx-1 system configuration
and maintenance tasks, within @ptitude Observer.
