Event Registration

This section provides an overview of the event registration functionality. The development of this feature was driven by user feedback received during the use of the OEE product. Initially, our implementation only supported start and stop events, limiting the ability to categorize events in finer detail.

To address this limitation, we introduced a more versatile system that enables organizations to establish multiple groups of event categories. Operators can utilize these groups to register various events occurring on machines. These groups have the flexibility to encompass numerous event category types, accommodating potentially hundreds of categories. Additionally, organizations have the capability to create multiple event category groups. This includes support for defining organization-wide application of event category groups, as well as the ability to assign different event category groups to specific machines.

Moreover, the event categories offer customization options such as custom icons, colors, and titles. They also support up to three levels of nesting, allowing for detailed categorization of events. This extensive customization capability ensures that the event registration process can capture a wide range of details.

Components

The various components in the event registration feature is introduced below.

Event Category Groups

An event category group is a container for event categories. The event category group can be applied organization-wide, or specific to one or more machines.

Event Categories

An event category is a simply a block describing an event. An event category has a title that makes it identifiable. It can also be customized with icons (FontAwesome icon selection) and coloring for easier identification among a set of other event categories.

Event categories support having a set of nested event categories, which again also supports having another set of nested event categories. This nesting behavior is currently allowed until 3 levels deep.

The top level event category also has parameters to define whether event logs created from it should count as operational or non-operational time, and if non-operational, if it should count as unscheduled downtime.

Note

Event category groups and event categories works as a live configuration that is used to register new logs/events from. The configuration can be modified at any time, supporting migration of existing logs into the new configuration, or resetting to start from scratch.

Event Logs

Event logs is the term for any logged/registered event of an event category. An event log is always created from an event category. Each time a new event is registered, it is stored with a timestamp, which user registered the event, and details of the event category that it was created from.

Tools

The event registration comes with tools to work with the already generated data, or to customize the configuration of event registration.

Template Center (Q4 2024)

The template center is a modal in the Hexastate app where users can easily re-use customized components in the system. In relation to event registration, it is possible to mark event category groups and event categories as templates for quick re-use or duplication to create a slightly modified configuration from.

Timeline

The timeline is a widget providing an overview of the events that has occurred on a machine. The timeline is a chart with zoom, time range filtering, and dragging functionality to allow users gaining insights in which events occurs on a machine in a visualization that is easy to understand.

Note

In unlocked mode, it is possible to modify the timeline of a machine retrospectively.

Analytics

For analyzing data generated with the event registration module, multiple widgets are developed being available in the "Dashboards" section found in the sidebar in the app.

Pareto

The pareto widget shows a column-like chart with the distribution between event categories measured in duration (seconds). Therefore, by analyzing data in the pareto chart, we can identify which event categories our machines is often spending time in and how many occurrences these are distributed into.

OEE

Based on the event registration data, detailed calculations of the OEE (Overall Equipment Effectiveness) of the machines. The OEE comes in 4 metrics: availability, performance, quality, and the 3 combined are used to calculate the 4th metric called "OEE".

Note

For highest quality data, Hexastate recommends installing sensors measuring the output and scrap of production lines and machines, which are included in the OEE calculations. This validates data quality and reduces risk of human error polluting the data.

When analyzing your OEE, we have integrated support for customizing your calculations to achieve finer granularity. For instance, you can specify which event categories should be included in the calculation, enabling you to focus on specific areas of performance. Additionally, we have implemented functionality that allows you to adjust the criteria for categorizing non-operational events, determining whether they contribute to degraded performance or reduced availability.

AI

Behind the scenes, Hexastate AI analyzes incoming sensor data to automatically determine the operational status of machines (provided sensors are installed on the machine). This process ensures high data quality, even in situations where users forget to log events or lack the ability to do so.

Note

All AI-registered events on a machine will be marked as "auto-detected". Use the "Timeline" tool to retrospectively edit the events into more detailed event categories.
