While many acronyms have become part of our common language, with their meanings well known to people in the industry, it can be entertaining to review the origin or decoded version of an acronym. The following list includes common acronyms found in the product documentation.
Acronym
Decoded
Description
ACL
Access Control List
Lists the users and permissions for system access.
AES
Advanced Encryption Standard
This security algorithm encrypts and decrypts data using the same encryption key. Software uses this standard to enforce privacy controls on each device and connection.
AMQP
Advanced Message Queuing Protocol
Open standard for business application messaging.
BPM
Business Process Management
This business solution focuses on optimization of business processes and workflows.
CDN
Content Delivery Network
Network nodes and content are located closer to the end user than with typical network configurations.
CIDR
Classless Inter-Domain Routing
The standard for creating unique identifiers for networks and individual devices.
CNC
Computer Numerical Control
This pre-programmed sequence of commands enables automation of machine tools.
CoAP
Constrained Application Protocol
Web-transfer protocol for IoT constrained nodes and networks; designed for machine-to-machine (M2M) applications.
CRM
Customer Relationship Management
This software manages a database of interactions with customers and potential customers.
CSR
Certificate Signing Request
Send this encoded file to a certificate authority for creation of an SSL certificate.
DCS
Distributed Control System
A computerized control system for a process in which autonomous controllers are present in the system without a central operator supervisory control.
DTC
Diagnostic Trouble Code
Engine control systems in vehicles issue DTCs for problems and failures. For example, a DTC triggers the check engine light in an automobile.
DTLS
Datagram Transport Layer Security
Protocol for secure communications for datagram-based applications (UDP transport protocol).
ERP
Enterprise Resource Planning
This software integrates and manages core business functions/units in a shared database.
ETL
Extract, Transform, and Load
This data warehousing term refers to a process of extracting data from one source, transforming the data, and then storing it in another database.
FTP
File Transfer Protocol
A network protocol that is used to transfer files between a client and a server.
HID
Human Interface Device
USB-connected devices, such as barcode scanners. In Litmus Edge, an HID remains disconnected because HIDs send data only when there is data to send.
IoT and IIoT
Internet of Things and Industrial Internet of Things
Communication among a large variety of devices and protocols, along with the collection of data from those devices, enables data analysis and efficient management and planning.
IPC
Industrial PC
PC-based computing platform for industrial applications.
MES

Manufacturing Execution System
This system tracks the processes, data, and outcomes–from raw materials to finished goods–of a manufacturing process. This includes such things as materials tracking, management of overall equipment effectiveness (OEE), and resource scheduling.
MQTT

Message Queuing Telemetry Transport
This lightweight messaging protocol uses a publish-subscribe method for connecting to sensors and devices.
NATS

Neural Autonomic Transport System

This messaging platform provides a text-based publish-subscribe protocol. This NATS name compares its functions with a central nervous system.

NTP

Network Time Protocol

Devices, including Litmus Edge devices, use NTP for time synchronization.
OAuth

Open Authorization

OAuth 2.0, an open standard for authorization and authentication, can be configured in Litmus Edge Manager. Other authorization methods supported in Litmus Edge Manager, include:
Query Auth (a method of signing API requests with a key)
Header Auth (HTTP authorization header)
OEE

Overall Equipment Effectiveness
The standard for improving manufacturing productivity.

OPC
Open Platform Communications
Standard interface used to communicate with industrial devices. Legacy solutions used this standard for accessing devices. As manufacturing systems evolved, a new interoperability standard, OPC UA, was developed by the OPC Foundation.
OPC DA
Open Platform Communications Data Access
An OPC Foundation specification that defines how real-time data can be transferred between a data source and a data sink (for example: a PLC and an HMI) without either of them having to know each other's native protocol.
OPC UA
Open Platform Communications Unified Architecture
This machine-to-machine protocol for industrial automation supports a Service-Oriented Architecture (SOA).
OTA
Over-the-Air
Over-the-Air updates facilitate device software updates. OTA refers to the methods for distributing software, configuration settings, and even updating encryption keys.
PaaS
Platform as a Service
Litmus offers Litmus Edge Manager, a cloud platform (PaaS) that provides connectivity with IoT systems to collect data that enables device monitoring and management.
PLC
Programmable Logic Controller
A specialized small computer with a built-in optimized operating system used in industrial machines and sensors.
RBAC
Role-Based Access Control
Enables customization of access control lists, which define who can access data, based on their assigned roles.
REST
Representational State Transfer
REST provides a web service for exchanging messages between devices. Application programming interfaces (APIs) can be used to glean essential information from JSON over HTTP (refer to REST API with JSON). Users can use REST APIs to develop their own interfaces.
SCADA
Supervisory Control and Data Acquisition
An architecture for industrial control systems that includes sensors, control relays, PLCs, computers, and applications that directly interface with managed systems. The SCADA HMI (Human-Machine Interface) enables interactivity with devices.
SOA
Service-Oriented Architecture
This approach to building systems focuses on business processes for which services need to be developed and supported. This is a departure from the development of systems that focus on hardware, software, and networking resources.
SOAP
Simple Object Access Protocol
SOAP provides a web service that defines a standard communication protocol for exchanging messages between devices.
SSH
Secure Shell
Protocol for secure communication over a network.
SSL
Secure Socket Layer
Protocol for secure communication over a network.
TFA
Two Factor Authentication
Adds an extra layer of security for user logins.
TLS
Transport Layer Security
Protocol for secure communication over a network.
