EAGLE DEVICES  Figure 5 : Eagle system   Photo générale du système Eagle (Gateway, Expander, Capteurs, alim., câbles
9  Brand of ACOEM 1.2.  EAGLE NETWORK La communication entre le PC et la Gateway se fait via un câble Ethernet cat 5e, en réseau local  uniquement.  Ni  le  PC,  ni  la  gateway  ne  peuvent  se  connecter  à  un  réseau  wifi  ou bluetooth environnant, ces services sont complètement arrêtés sur le PC et inexistant sur la Gateway.  Le  réseau  local  de  communication  est  physiquement  séparé  de  tous  réseaux environant. 1.2.1. Basics    Figure 6 : basic Eagle network 1.2.2.

10  Brand of ACOEM  1.3.  RADIO COMMUNICATION 1.3.1. Characteristics Parler de l’ISA100.11a L’ensemble des produits utilise la bande de fréquence ISM 2.45GHz. Bande de fréquences regroupant entre autre le wifi, bluetooth,  zigbee... Cependant, la modulation utilisée par la couche  PHY  (O-QPSK)  ne  permet  pas  de  décoder  physiquement  les  données  wifi  et bluetooth, seulement les données 802.15.4 PHY. Les capteurs émettent à +3dBm, soit 2mW et les éléments du réseau (routeur et gateway) à +13dBm (20mW). 1.3.2. Radio standard L’ensemble  des  produits  utilise  le  protocole  radio  802.15.4e.  Cela  permet  d’avoir  de  base certaines sécurités quant aux échanges de données entre les différents éléments du réseau radio. En effet, chaque élément du réseau possède une adresse MAC unique codée sur 64bits. Cette adresse identifie un capteur unique sur un réseau unique. De plus, pour qu’un élément  puisse  rejoindre  un  réseau  radio  existant,  il  faut  qu’il  connaisse  l’identifiant  du réseau, codé sur 16bits. Pour encore plus de sécurité, lors d’installation sensible comme en milieu  industriel,  il est  possible de  rajouter une  “liste  blanche” sur  la gateway, qui filtre sur adresse MAC et n’accepte sur le réseau que les éléments présents dans cette liste. 1.3.3. Radio coverage En  champ  libre,  les  capteurs  peuvent  avoir  une  portée  radio  d’envrion  100m.  En environnement perturbé, et/ou industriel, la portée dépend énormément de l’environnement et des essais sur place sont nécessaires. Une portée d’environ 20m est plus réaliste dans ce type d’environnement. De même que pour les capteurs, la portée radio de la Gateway et des routeurs est fortement dépendante de l’environnement. 1.3.4. Security

14  Brand of ACOEM  Chapter 2 INSTALLATION GUIDE
15  Brand of ACOEM 1.  SITE SURVEY RF planning should be considered from the onset in order to determine the sensor locations and options for the expanders and gateway installation. In  the  vast  majority  of  cases,  the  RF  requirements  do  not  impede  the  installation  of  the sensors but by considering the RF implications from the start a very good first-time success rate is achieved.  The typical link budget calculations that are used in radio planning are not valid in the vast majority of industrial environments and accurate RF modelling is far too time consuming to be practical. For this reason, the  RF planning  is simply  guided by empirical data gathered from  a vast array of previous installations. A set of best practices are presented which are effortless to follow and  delivers  reliable  performance  without the  need for  calculations  or sophisticated survey equipment. 1.1.  SITE PLANNING The very first step is a site planning for RF (radio frequency). On a site map:   Determine and identify the machines that require monitoring with Eagle sensors,   Determine potential locations for the gateway (allowing connection to the PoE <100m, power connection <100m).   Estimate the distance from every Eagle sensor to the gateway after the initial survey and use the table below to determine whether special precautions need to be taken. Table 8 : distances for coverage quality Environment Simply Works! Special Precaution Dense metal structures with no line-of-sight 20m 50m Sparse metal structures with limited line-of-sight 30m 100m Line-of-sight 100m 400m    Identify obstacles that can interfere with radio coverage, sensors in complex areas (limited space, metal shields) and the most distant sensors.      des schémas avec plusieurs implantations possibles
16  Brand of ACOEM  Figure 12: site survey example where all the information needed are identified 1.2.  FIELD TEST The second step is a field test to verify the reception of the farthest sensors or those with doubts  about  their  reception  because  of  their  situation  (metallic  surroundings,  casing, guards...) and  Perform  a  temporary  installation  in  order  to  try  out  different  gateway  options  and  Eagle sensors locations. 4.  VERIFY THE PLAN WITH A TEMPORARY (OPTIONAL) INSTALLATION  When  the  planner  is  not  confident  due  to  inexperience  or  due  to  a  particularly  tricky installation,  it  is  warranted  to  perform  a  temporary  installation  in  order  to  try  out  different Gateway antenna options and Eagle Field Device locations. Typically the Eagles within the “Just  Works!”  range  are  installed  permanently  from  the  onset.  The  remaining  Eagles  are temporarily  moved  to  the  suspected  troublesome  locations  and  their  signal  strength monitored using the  gateway web application. It is common practice to immediately install the Eagle permanently once the link quality is confirmed. The  signal  strength  of  every  device  can  be  monitored  from  the  web  application  of  the gateway. It is advisable to improve the signal strength for devices lower than -80dBm. Table 9 : signal strength qualification Signal strength Quality Action -30 to -50 dBm Excellent   -50 to -60 dBm Good   -60 to -80 dBm Fair  Can be improved using an expander < -80 dBm Poor  Must be improved using an expander < -90 dBm Out of coverage  Must be improved using an expander  ILLUSTRATION SITE SURVEY
17  Brand of ACOEM 2.  INSTALLATION PREREQUISITES 2.1.  SAFETY Refer to safety instructions, safety standards and procedures before installing any device. 2.2.  SITE SURVEY At this step the site survey is done. The location of the gateway, sensors and expanders are identified in a site plan and ensure to each sensor the appropriate radio coverage. 2.3.  FASTENING SUPPORT The gateway must be placed on a wall or a pole at a height of about 5m [16 ft]. Adequate mounting support has to be installed on site (such as mast) if necessary and can therefore require the use  of support facilities and  operations of specific civil  engineering if needed for the configuration of the area. 2.4.  NETWORK AND POWER The gateway has to be powered and connected to the customer IP network Prior to installation, the site must be equipped with both power and ethernet connections. A technical cabinet can be necessary. The link to the customer IP network can be fiber-optic, copper…
18  Brand of ACOEM 3.  GATEWAY INSTALLATION The gateway is fully assembled and ready to be deployed upon delivery. Only  one  gateway  is  necessary  to  ensure  the  operation  of  the  whole  multi-hop  wireless infrastructure. Additional gateway may be necessary depending on  The gateway is linking the wireless network of Eagle devices (ISA100.11a) to an IP network where the data are processed. In hazardous environments, the operator has to arrange organizational safety measures which reliably prevent the occurrence of an ignitable atmosphere, by default reduce the probability that a flammable atmosphere can occur at all (employing the use of suitable gas detection systems). 3.1.  LOCATION The location of the gateway is very important.   It must be placed at a height of about 5m [16 ft].   It must comply with a maximum radius of 100m [328 ft] radio coverage.  The  housing face  with OneProd  logo  indicates  the embedded antenna  location.  This face must be oriented in the direction of the sensors and expanders. The  radio  link  is  sensible  to  physical  obstacles,  such  as  vehicles,  tanks,  or  walls.  If  the distance between the gateway and sensors or expanders exceed 100m [328 ft], it may be necessary to add an additional expander to improve the signal strength.

19  Brand of ACOEM 3.2.  MOUNT A damp cloth should be used when installing or taking off the gateway in hazardous areas to eliminate static electricity resulting from this operation. The  gateway  is  fixed  very  quickly  on  a  pole  or  on  a  wall  using  a  ball-joint  mount (EGL1208000). The ball-joint mount is constituted of:   A ball-joint head Fixed on the bottom of the gateway using M8 screw and bolt.  A ball-joint base The base is to be pegged on a wall or on a pole.   The mounting on a pole requires a clamp, nuts and washers.   The mounting on a wall is done using four screws and anchors.   The mounting on a structure requires bolts nuts and washers.  An arm The arm is joining the two ball-joints allowing precise orientation of the gateway.  Figure 14: ball-joint base, arm and ball-joint head from RAM mounts (EGL1208000)  Figure 15 : mounting on a wall  Figure 16 : mounting on a pole (clamp detail)
20  Brand of ACOEM 3.3.  CONNECTION TO THE GATEWAY The  gateway  is  powered  and  connected  to  an  IP  network  by  a  unique  cable  (ethernet category  5e)  thanks  to  a  PoE  (Power  over  Ethernet)  injector  (compliant  with  802.11.3af-2003). Prior  to  installation, the  site  must be  equipped  with  both power  and  ethernet  connections where  the  PoE  will  be  installed.  A  technical  cabinet  can  be  necessary.  The  link  to  the customer IP network can be fiber-optic, copper… No hazardous on-field cabling!   The ethernet cable must not be connected to the other end.    The operator has to prevent the occurrence of an ignitable atmosphere (employing the use of suitable gas detection systems).  Figure 17 . gateway connection The Ethernet connection to the gateway is tool free.   Use  a  standard  Ethernet  Category  5e cable  pulled  from  a  technical cabinet (not Step 1. connected).    IP68 gland is delivered with the gateway housing and has to be mounted on the Step 2. Ethernet cable before connecting the gateway. Figure 18 describes this procedure.   Plug the assembly in the waterproof Ethernet receptacle located on the back of the Step 3. gateway.    Ensure that the assembly is fully tighten Step 4.

21  Brand of ACOEM  Figure 19 : cable, gland and connector assembled 3.4.  CONNECTION TO THE POE  Attention le POE doit être hors zone ATEX.    The PoE is preferably located close to the gateway (sauf en zone ATEX)but can be located at 100m max (Ethernet limitations). Manage cables by using different colors to differentiate PoE from LAN. Define  a  standard  that  is  relevant  to  your  requirements  or  the  one  in  application  in  your company.   Blue or Grey for Network (LAN)   Yellow or Red for PoE  Be careful when connecting. Check twice that “PoE” port is connected with the gateway. Wrong connections may cause damages   Connect the ethernet cable from the gateway to the PoE injector on the "PoE" Port. Step 1.  Connect "LAN" port of the PoE to the IP network. Step 2.  Check your connections Step 3.  Power the PoE using the appropriate power plug for your country. Step 4.

23  Brand of ACOEM 4.  SENSORS INSTALLATION 4.1.  SENSOR LOCATION The  sensors  are  mounted  on  the  equipment  to  monitor  following  the  rules  for  vibration sensor installation. Leave enough space around the sensor to ensure the best transmission/reception possible of radio signals. At least 100 mm around the device antenna (plastic cap). If the sensor has to be installed in tiny spaces, the use of an expander might be a solution to improve the radio coverage (if necessary).  Figure 23 : clear space around the sensor/expander 4.2.

This allows testing locations and orientations of the farthest sensors or those with doubts about their reception because of their situation (metallic surroundings, casing, guards…) to get the best coverage possible. A magnetic mount is the best solution in that specific case.   Screw the sensor on the magnetic base using appropriated stud or bolt (M6). Step 1.  Place the system on the location to test Step 2.NOTE: An adapter stud may be required depending on the design of the magnetic base to allow M6 mount.

It  must  be  located  in  the  coverage  of  the  gateway  or  of  another expander. It  is  best  practice to  install  the  expanders  at  high  to  improve  the  coverage.  This  way  the expander has a clear view of the sensors close to it. The blue plastic cap is where the embedded antenna is located. It must be oriented in the direction of the sensors or at least vertically. The  radio  link  is  sensible  to  physical  obstacles,  such  as  vehicles,  tanks,  or  walls.  If  the distance between an expander and sensors exceed 50m or an obstacle is present, it may be necessary to add an additional expander to improve the signal strength. 5.2.  EXPANDER MOUNTING A damp cloth should be used when installing or taking off the gateway in hazardous areas to eliminate static electricity resulting from this operation. Expander  shares  the  same  design  as  sensors.  See  “Figure  24:    sensor  and  expander mounting interface (threads, hex head)” on page 31.

45  Brand of ACOEM 2.  PERIODICITY Normal  use  of  the  product  corresponds  to  a  daily  measurement  and  no  more  than  6 measurements per day. Below 4h of periodicity (minimum theoretical periodicity is 10 minutes) many parameters can affect periodicity and battery life. The numbers of sensors of one network (paired with the same gateway) is a parameter. The more they are, the larger is the minimum periodicity. This is due to the sum of time needed for each sensor to send its data. The signal strength is another parameter. The weakest the signal, the longer the upload.     3.  AUTONOMY The expected autonomy when measuring the recommended configuration is: Periodicity Uniaxial Triaxial 8-24 hrs > 5 years ~ 5 years 6 hrs > 5 years ~ 3 years 4 hrs ~ 4 years ~ 1 year  Things that will make this Autonomy worse:  RF link: poor RF link will cause large transfer duration or the signal to fail to transmit and retry, which uses up power.  Temperature: Extreme temperatures makes the electronics use more power and the battery to have less potential capacity.  Signals: aggressive waveforms configurations or high quantity of signals make data bigger and increase the transfer duration.  Periodicity: too short periodicity increases the number of measurement requests and transfers. All this points are interconnected; the goal is to find the appropriate balance.   0:000:301:001:302:002:303:003:304:004:30010 20 30 40 50Minimum periodicity (h) Number of sensors / gateway Impact of sensors on periodicity TRIAXIALUNIAXIAL
46  Chapter 6 GATEWAY WEB INTERFACE The gateway web interface allows to change multiple settings and to monitor signal strength. 1.  CONNECT TO THE GATEWAY INTERFACE   Force your computer IP address to the same subnet as the Gateway (ex.: 192.168.0.100) and test whether it responds to pings. The Gateway has two IP addresses. The configurable and failsafe address 172.17.17.17.   Connect to the web-interface at http://< IP address> (ex. : 192.168.0.112) and log into its Monitoring and Control Portal with the username and the password provided on the Factory Settings Report received with the delivery.      The Network / Devices page will display the connected hardware. The Gateway incorporates 3 ISA100.11a components namely the System Manager, Backbone Router and Gateway. All three should be present in the Devices list.   The paired and powered field devices should appear in that list. 2.  MONITOR SIGNAL STRENGTH After the Eagle  has joined,  the  Gateway Backbone  will  start recording the  received signal strength from every device.  Click on the Backbone’s EUI-64 address on the Network / Devices page and then on the Neighbours Health tab. Click Refresh. A  list  of  Eagle  Field  Devices  together  with  their  signal  strengths  and  packet transmission statistics will be displayed. Note that the information will not be available immediately for a newly  joined  device  because  the  Eagle  Field  Device  is  designed  not  to  transmit unnecessarily  in  order  to  conserve maximal  battery  life.  Therefore  the  Backbone  requires some time in order to build up an accurate record of the received signal strength. A  typical  installation  should  aim  to  have  the  signal  strength  of  all  Field  Devices  larger than  -80dBm  in  order  to  maintain  a  reasonable  fade  margin  and  ensure  robust communication. The following sections provide details of how to plan an installation how to maximize performance. Note that the update of this information is not instantaneous and can take up to 5 minutes. The gateway must test the connection with all the sensors. The aim is to achieve a signal strength: above -80 dBm and definitely not below -85 dBm.
47  Brand of ACOEM Chapter 7 RADIO INSTALLATION GUIDELINE RF planning should be considered from the onset in order to determine the sensor locations and options for the Gateway installation. In the vast majority of cases, the RF requirements do not impede a sound mechanical installation of the Eagle Field Devices but by considering the RF implications from the start a very good first-time success rate is achieved.  The typical link budget calculations that are used in radio planning are not valid in the vast majority of industrial environments and accurate RF modelling is far too time consuming to be practical. For this reason, the RF planning is simply guided by empirical data gathered from a vast array of previous installations. A set of best practices are presented which are effortless  to  follow  yet  delivers  reliable  performance  without  the  need  for  calculations  or sophisticated survey equipment. 1.  INITIAL SITE SURVEY Conduct  the  first  site  survey  in  order  to  determine  the  points  that  require  monitoring  and identify potential Gateway and antenna locations. Choose  the  location  that  offers  the  smallest  distance  to  the  farthest  group  of  Eagle  Field Devices. Be aware of the RF cable loss if the antenna will be placed far from the Gateway and bear in mind that every 3dB loss will roughly reduce the range by 30%.  Test the reception of the farthest sensors or those with doubts about their reception because of their situation (metallic surroundings, casing, guards...). 2.  CHOOSE A SUITABLE ANTENNA In order to select the correct antenna for the Gateway and ensure a successful installation, a basic understanding of antenna specifications and how they operate is presented. 2.1.  RADIATION PATTERN An antenna receives a finite amount of power at its port from the Gateway and focuses this power when transmitting it according to its “radiation pattern” which is simply describes how the antenna focuses the transmitted power.  The antenna will focus the power more in one direction than another an important concept to grasp is that when it focused more power in one direction it has to take that power away from other directions. That is why a higher gain antenna has a narrower beam width.  In the same narrative, when an antenna is listening more intently in a direction it will have a diminished “listening” ability in other directions. Antennas also behave according the physical law  of  reciprocity,  meaning  that  the  focus  of  an  antenna’s  “listening”  ability  is  exactly  the same  as  its  transmitting  focus.  In  other  words,  the  “radiation  pattern”  is  identical  to  its “reception pattern”.  It  is  best  practice  to  choose  an  antenna  with  a  radiation  pattern  that  will  focus  as  much power in the direction of the Eagle Field Device installation and not waist energy in directions where  there  are  none.  For  example,  use  a  sector  or  panel  antenna  and  not  an omnidirectional antenna if it is located at the one end of all the Eagles. Some common antenna types are shown below together with an illustration of their radiation patterns.
48   2.1.1. Polarization Antenna polarization is another property which the installer must bear in mind especially in an environment with few obstacles.  A radio  wave  travelling in  free  space contains an  electric  field pointing in  a perpendicular direction to that of the propagation.  The orientation of this electric field in the antenna’s main beam is referred to as the antenna polarization. The electric field is described as either linear or circular which means that the field is either orientated along a single axis or rotating as the radio wave passes a point in space.   The  Eagle  is  linearly  polarized  in  the  direction  of  its  height  and  in  order  to  achieve  the maximum range it must be orientated in the same direction as the polarization of the incident radio  wave. It is  important  to  note  that  due to the  prevalence  of conductive  surfaces  in a typical industrial environment, the incident radio wave polarization is likely not to be as the purely  polarized  as  the  wave  emitted  in  the  Gateway  antenna.  This  randomizing  of  the polarization due to the interaction with conductive structures is why a good signal strength is practically always achieved within 30m regardless of the Eagle orientation.  Never-the-less, being cognizant of the effect of polarization is very important and changing either  the  Eagle  or  Gateway’s  antenna  polarization  is  one  of  the  tricks  discussed  later  in order to improve the signal for hard to reach Eagle.  The table below lists the signal loss due to a mismatch in polarization.  Incident Wave  Polarization Eagle Orientation Offset Polarization Mismatch Loss Linear 0° 0dB Linear 180° 0dB Linear  45° 3dB Linear  90° ∞ Circular Left-Hand Any Direction 3dB Circular Right-Hand Any Direction 3dB    Omnidirectional Panel antenna Sector antenna
