Trigger-based data collection allows users to set up a set of data points to be collected when a specific trigger event occurs on the machine, as detected by a change in the value of any one data point. This means a trigger-based collection job might collect data several times in a minute, or only a few times in a day. This article explains how you can get started with your own trigger-based collection setup.

Set Up Devices

From the Remote Service Platform, in the Admin > Machines page, search for the machine you want to configure, then select the Devices icon  to open that machine’s Devices page.
If you can’t access this page, reach out to your platform administrator for assistance.
You can either modify an existing device defined in ei3 for the machine to use trigger-based data collection, or create a new one. To create a new device, select the icon to open the device creation page. You will need to choose one of the two defined device types from the drop-down selection tool. Currently there are only two device types defined in ei3 which suppport trigger-based data collection. These devices are:
  1. B&R – Milacron
  2. Generic – OPC-UA
Click the Save icon  at the bottom of the page once you’re done with entering all the device information.

Define the Trigger Data Point

A single data point on the machine must be defined to use the data point Tag Type called Collection Trigger. You can designate this data point by selecting the Collection Trigger type for that point from the Tag Type selection menu on the Edit Data Points page. Remember that only a single data point per machine can be set as the Collection Trigger. Whenever the Collection Trigger data point changes its value, then all data points defined for the machine as Trigger points will be collected. To set these up, see the next step in this article. You can also apply a scale equation to Trigger data points on this page, if one is needed – the values are stored in ei3’s web-based cloud and are accessible via existing API capabilities. Select a Scale Type from the drop-down menu and then enter the values for the scale equation as needed. Keep in mind, however, that scale equations are not applied locally in Amphion Edge devices when Trigger data is obtained from the Amphion directly. (Amphions will need to connect to ei3’s web services for the scale equations to be applied).

Define Trigger Data Points

Once one device is defined as the source of the Collection Trigger data point, and a data point has been defined as the Collection Trigger, the next step is to defined the trigger data points on the machine, which are the points that will be collected each time when the trigger event occurs. You can do this from either the Remote Service Platform or the Customer Portal.

 In the Admin Tools > Data Points web page, choose the points you’d like to enable for trigger-based collection by clicking in the column Trigger Data (scroll right on the page if you don’t see it). The icon will toggle from disabled  to enabled . You can always toggle it back if needed.

If you don’t see a column for Trigger data, your machine is not properly configured to support it. Try reviewing the steps above or contacting a platform administrator for support.

View Trigger Data

If the Remote Monitoring product is not active on your machine, you won’t be able to view this information. Contact ei3 support for assistance with activating this product if you don’t see it.
For ei3 customers with this feature enabled, you can view your trigger data in the Customer Portal, under Remote Monitoring > Charts > Injection Data.
