# Glossary

## A

#### Active variable

A machine variable that is being recorded and accessible by all ENLYZE platform services.

#### Computed variables

Variables that are not read directly from the controller but are derived from raw data through calculations (e.g. rates from counter values, sums, status mapping). See [Computed variables](https://docs.enlyze.com/en/understanding-machine-data/variables-and-time-series#computed-variables) for details.

## B

#### Batch record

Documentation of a production run. Based on the SOP/setup sheet, it compares actual values against defined bounds for each production run.

## C

#### Co-Pilot

Operator assistant in the ENLYZE App. Displays the variables defined in the SOP/setup sheet with configured bounds compared to live machine data. Highlights deviations for the operator.

#### Contextualization

Has two meanings depending on context:

1. **For downtimes:** Assigning reasons to downtime events.
2. **For variables:** Selecting a parameter and adding a display name, unit, and scaling factor.

## E

#### Edge Device

The ENLYZE edge device (formerly known as SPARK). Connects to data sources, reads selected data points, and streams them to the ENLYZE Manufacturing Data Platform. See [Edge Device](https://docs.enlyze.com/en/connect/edge-device) for details.

## D

#### Data source

A physical or virtual OT device connected to the ENLYZE Manufacturing Data Platform via a connector to collect process data. Examples: PLCs (Siemens S7-1200), Modbus energy meters, OPC-UA servers.

#### Display name

A human-readable name assigned to a variable within the ENLYZE Manufacturing Data Platform. Not present on the data source itself but added during contextualization.

#### Downtime

A period where a machine is not producing. Automatically detected when a defined parameter falls below a configured threshold. See [Downtimes](https://docs.enlyze.com/en/concepts/downtimes) for details.

## G

#### Golden Run

The production run for a product that achieved the best combination of performance and quality. Marked with a trophy icon in the ENLYZE App. Downtimes are not considered when determining the Golden Run.

## L

#### Lead variable

A variable that serves as the basis for automatic downtime detection. Typically a speed, throughput, or cycle rate. When its value falls below a configured threshold, a downtime is detected. See [Detection](https://docs.enlyze.com/en/concepts/downtimes/detection) for details.

## M

#### Machine data

Data extracted from a data source in time series form and associated with a specific machine.

#### Maximum Demonstrated Speed (MDS)

The highest stable production speed achieved for a specific product on a specific machine. Automatically calculated from production history and used as the product-specific performance reference for OEE. See [Maximum Demonstrated Speed](https://docs.enlyze.com/en/concepts/performance/maximum-demonstrated-speed) for details.

## O

#### OEE (Overall Equipment Effectiveness)

Metric for equipment effectiveness. Calculated as availability x performance x quality. An OEE of 100% means: no downtime, maximum speed, no scrap. See [Understanding OEE](https://docs.enlyze.com/en/concepts/understanding-oee/the-oee-concept) for details.

#### OT (Operational Technology)

Technologies for controlling physical processes, devices, and infrastructure in manufacturing. Examples: PLCs (programmable logic controllers) and sensors.

## P

#### Platform Grafana

The ENLYZE-hosted Grafana instance where production data can be visualized as dashboards.

#### Production context

The connection of machine data with order data. Machine data shows how production happened. Order data shows what was produced. Together, they enable analyses such as OEE, target-actual comparisons, and product analysis. See [Production context](https://docs.enlyze.com/en/concepts/production-context) for details.

#### Production order

The overarching instruction to produce a specific quantity of a product. Typically comes from your ERP or planning system.

#### Production run

A slice of time that reflects the actual execution of a product on a machine. Production runs are the basic unit for calculating and tracking OEE. Each run is assigned to one machine, produces one product, and has a clearly defined start and end time.

## S

#### Setup sheet / SOP

Machine settings for a specific product. Defines target values, bounds, and limits for variables per product. Basis for Co-Pilot and batch record.

## T

#### Time series

A sequence of measurement values with timestamps that documents the progression of a variable over time. ENLYZE records variables as time series by querying the current value from the data source every 10 seconds. See [Variables & time series](https://docs.enlyze.com/en/concepts/understanding-machine-data/variables-and-time-series) for details.

## V

#### Variable

A measurement or control value that changes over time and is provided by a data source. Variables are centrally managed within the ENLYZE Manufacturing Data Platform and can be recorded.

#### Variable Discovery

An automated process where an Edge Device queries the variables available on a data source and registers them in the ENLYZE Manufacturing Data Platform. Supported by protocols such as S7+, OPC-UA, OPC-DA, PVI, and Beckhoff ADS.
