Definition, Types and Structure
Templates are xml files which contain all the sensor configuration for all the sensors. This includes sensors, actions, rules and everything the azeti SiteController is programmed to do. This file will later be deployed to each site.
Here is an example of a simple template:
The templates are divided into the following:
- Components: This are the basic building blocks. They represent a certain physical sensors, and include all the data points, connection information, etc. necessary to make it work. They have to be created manually with a text editor and uploaded to the server. azeti already posses a library of ready to use components. For example, a component would be the template for the Comet Temperature Sensor. The components can be shared across organizations, but cannot be edited.
- Component Instances: This are copies of the compoments. They are local to each organization, and can be edited using the built in editor of the cloud. Most common reason for editing would be to adapat the connection info of the sensor (for example, the IP address). Several component instances can be created from the same component, and they will share the same configuration. For example if there are several temperature sensors on the same site, several temperature sensors component instances have to be created from the same temperature sensor component.
- Site Templates: The site template includes all the sensors that a site has. This means it has all the component instances for all the sensors of that site or type of site. The same site template can be assigned to several site, so that if all the sites have all the same sensor any change has to be done only to the site template in order to all the sites to get it.
- Location Templates: The location templates are site template customized for an specific site or location. They can only be assigned to one location, so they are use for only specific changes (for example to change the size of a fuel tank).
Hierarchy and inheritance
The logical structure to build the templates is:
All the changes done to a template are inherited to the templates below them. So if a sensor inside component instance is edited, all the site templates and locations templates that use it will be edited as well automatically. The exception being those changes that were done directly on the lower template. So if, for example, sensor X state threshold is changed on a site template, and then on a component instance, the change done directly on the site template will take precedence, and the change done on the component instance will not be applied.
Using Components and Components instances
The first step to create a template would be to upload one:
- Go to Management→ Templates → Components
- Click the +Add button
- Choose the file and click upload
Once uploaded the component will show in the list. It can be found using the search box and the top left of the page, or using some of the filters. The options then are:
- View: Will show the xml content of the template
- Validate: This will validate the xml content against the xsd to check that the file is syntactically correct. Being incorrect will not invalidate the upload, as it can be fixed later on the component instances of site templates.
- Upload Image: And image file can be uploaded to be shown on the page, beside the component name. Can be, for example, a sensor picture or a vendor logo.
- Share: To share the component with another organization.
- Delete: Permanently deletes the template. It is now allowed it the template is in use.
After the component template is uploaded, a component instance that uses is it can be created:
- Go to Management→ Templates → Instances
- Click +Add to create a new instance
- Select the component which will be the base for the component instance. Change the name of the instance if needed and click Add to create it, or Add and Edit to create it an go directly to the edit page.
Once the instance is created it can be edited at any time by click on the edit button of the same page (see Editing Templates and Components). Other options are:
- Validate, against the xsd, to check that is syntactically correct.
- Clone, to make a exact copy of the template.
- Delete, to permanently delete the instance. Will only work if is not being used.
Creating and Editing Site Templates
The site templates are the ones that will be assigned directly to a site. Typically they will exist as many site templates as types of site, meaning types of sites as those that have the same sensors and configuration.
To edit or create a site template go to Management → Templates → Site Templates
Each templates shows:
- If is the default template
- The name of the template (as set when created)
- The version (as set when created)
- The revision (set automatically by the system with each editing)
- The used instances (the component instances the make this site template). Click over it to show the list and click on a name to go directly to the component instance.
- The creation date
- The last update date
- The number of locations that have assigned this template. Click on the number (Admin & Live table. ) to see the complete list. Clicking on a name will take the user to the site
- The actions available for the each template, which are:
- Edit To edit the template content (see Editing Templates and Components)
- Set Default To set the template as the default to be deployed to the sites that have the auto deployment enabled.
- Delete To delete the template permanently. This cannot be undone, and is only available when the template is not in use by any site.
To create a new site template click +Add. Choose a name and version and click Create.
Once create the new template can be edited in the normal way.
Editing Templates and Components Instances
Both the Site Templates and the Component instances can be edited in the same way. The editor page they both use is the same, and can be reached click on the Edit button on both the Component Instances page and the Site Templates page.
Once into the editor the whole xml template is shown as a tree. To expand each tree node click the +.
Expanding the tree lets the user select a sensor, device, action or rule. Once selected the complete tree and configuration for that node is shown:
To actually make any change, click the Toggle SU/Normal mode button . This will change the template into the Edit mode.
Once in edit mode all changes can be done:
- Add new sensors/devices/actions/rules from a component
- Add empty new sensors/devices/actions/rules
- Edit the existing elements
The system configs are the system Site Controller configurations. This can be created and deployed from the cloud. Once installed on the Site Controller they become the SiteController.cfg (stored under $SiteControllerPath$/config/SiteController.cfg).
To manage the system configurations go to Management→ Configurations
To create a new one:
- click +Add
- Select the base component for the config. This are the Site Controller packages that are uploaded to the cloud (see Controller Software section). They have to be upload before creating the system config.
- Click + Next
- Edit the system config name and click + Create Template
Once the template is created it can be edited with the button Edit. This takes the user to the edition page.
This will show all the sections of the configuration file as a tree, with the values on the left side. To change this values click
For the deployments, jobs, updates and validations to be done correctly, the correct version of the site controller has to be uploaded to the server. To see which ones are already uploaded go to Management→ Software → Software Packages.
The list shows all the site controller packages that have been uploaded, with the all the details and the possibility to download it.
To upload a new version click +Add and upload the new package.
To send the Site Template to the site, upgrade the software, or update the SiteController configuration, go to Management → Provisioning → Deploy
The list of online sites will be shown. The following filters can be used to filter down the sites:
- Sites: pressing the button will show the location tree that allows to filter the alarms by location or region (as defined on the location tree).
- Online: If left checked, it will only show the alarms from online sites. Uncheck to show the alarms of all sites (both online and offline).
- Site Template: Select only the sites with an specific Site Template.
- Site Configuration: Select only the sites with an specific Site Configuration.
- Controller Software: Select only the sites with an specific Site Controller software version.
The information shown for each site will be:
- Site Name
- Site Template assigned. This is the sensors configuration. In green will show the current running version. In red or orange it will show the latest configured version, waiting to be deployed. In this case a deployment is needed to be have the latest version running.
- Site controller configuration filed. In green will show the current running version. In red or orange it will show the latest configured version, waiting to be deployed. In this case a deployment is needed to be have the latest version running.
- Controller Software Version
Single Site Deployment
To deploy to a single site click on the deploy button next to the site. A new window will appear:
There select the kind of deployment to be done: Site Template, Site Configuration or Controller Software. By default Site Template is selected. If the template is valid, then a green check mark will appear next to the site name: Schedule to trigger the update. If the template is not valid the Schedule button will be shaded and cannot be pressed.
If a red mark ( ) appears that means the site template is not valid, and the deployment will not be done. In that case please check the site template. If valid, press
After the deployment is done, if successfully sent, a green check will appear next to the site config (
). If not it will show a red cross ( ). On the bottom of the screen the reply messages from the Site Controller will appear:
Multiple Site Deployment
To deploy to multiple sites at the same time, select the sites using the check boxes at the left. Selecting the checkbox on the top will select all visible sites.
Use this in combination with the filters at the top of the page to deploy only to specific sites. The Sites Tree filters can also be used to deploy only to sites in certain location group (open the tree on the top left, click on the icon to the left of the group name)
Once the sites are selected, click the Deploy button on the top left.
The number displayed there is the number of sites that will be updated. After pressing the Deploy the same page as for the single deployment will appear:
In this case it will show all the sites to be deployed, with a mark indicating that the template is valid and ready to deploy (green check If any of the sites templates is not valid the Schedule button will be shaded and cannot be pressed. If all the templates are valid press Schedule for the deployment.
) or no (red cross ).
