An Asset Hierarchy is Key for Workflow Productivity...
For large operations, it is unlikely that its asset hierarchy will match the limited number of levels in a PdM plaform. So a naimg convention will have to be set up. And, its best to have this set up outlined before actual sensor installation on assets. The challenge is creating an naming methodology that fits within these reduced levels and is intuitive for matinenance technicans using the dashboard.
WHY IT MATTERS: Asset naming has a big impact on both the setup and operation of a PdM platform. For setup, assigning names can be difficult and a laborious process. For operations, a consistent naming convetnion requires intuitive design that will be descriptive for technicians but will fit within the rules of the platform itself. Design as naming system that will work at scale.
NOTE: Use the Monitron documentation as your primary reference [ref]. The following tips are meant to be supplemental.
The approach below of naming and installation approach is for Amazon Monitron, but applies to any PdM system.
STEP 1: Build an asset name hierarchy
The hierarchy is important becuase it is used to display sensor names in the Monitron dashboard.
Layout your hierarchy, not just for the pilot but also for deployment across sites, total operation. It should use common wording and be easy to interpret and navigate for mainentance technicians.
Given the rules of naming in the dashboard entry, it is unlikely the hierarchy for the Monitron dashboard will match your existing asset heirarchy.
Name heirarchy will match thes levels:
AWS Account > Project Name > Site Name > Asset Name > Position Name
AWS Account info does not show in the dashboard.
Quotas in Asset Hierarchy
Accounts – Assign an account per geography or region will allow more flexible use of the names below.
Projects – For smaller customers, all assets can be directly managed within a project. User can choose to bypass the site layer.
Sites – For larger customers, multiple sites can be created under a project and each project managed separately as a combination of sites.
Assets – These can be complex assets that will have multiple sensors or production lines, portions of a production line.
Sensor Positions – Multiple sensors can be paired to multiple different positions of an asset or production line.
Creative use of names can greatly expand sensors per site. B
Monitron is only supported in two regions [ref]:
Using the above name quotas, craft a hierarchy spreadsheet with column headers that correspond to the above layers (except Account). Add names to create the hierarchy. This will speed the building of the hierarchy and help names to be defined in a more intutive way. The spreadsheet will speed that process of sensor pairing described in Step 2 below.

STEP 2: Pair sensors to the cloud
Sensor pairing to the cloud is done with a smartphone that connects each sensor to the AWS cloud through a gateway that is connected to the internet [reference].
There are two ways to perform the sensor pairing:
Monitron documentation suggests it be done at the asset location, the time of installation. This works great except for noise, safety and delays operating in a production environment.
Our approach is more productive – do the pairing of all sensors in a conference room or at a workbench.
Using the hierarcy spreadsheet, add a column that assigns a unique number to each sensor, eg, 1 to 50, and its asset name description.
Unbox all Monitron sensors and using a black marker, write a unique number on the top case of each sensor, eg, 1 to 50.
Then pair each sensor and assign it the name hierarchy matching it's number.
Must have a gateway operating in proximity of the sensor.
Confirm sensor name and operation in the Monitron dashboard.
STEP 3: Physically attach sensors to assets and positions
Check that gateway(s) are installed within 20-30 yards of sensors [ref].
It is not necessary for the same gateway used in pairing to be used for final connection.
At each asset, locate the sensor that matches number on hierarchy spreadsheet.
Install (Mount) sensors on assets that have matching numbers [ref].
Confirm sensor operation in dashboard [ref].
