Manufacturing terms defined plainly
The vocabulary you'll hear on a cosmetics packaging line — from PackML to micro-stops — explained without consultant-speak. Useful for plant managers briefing finance, IT teams onboarding to OT, and anyone evaluating production AI
PackML
Packaging Machine Language. An OMAC standard that defines a common state model — Stopped, Idle, Suspended, Held, Execute, Aborted — and TagName conventions for packaging machinery. PackML lets a monitoring platform read state and counters from machines built by different OEMs (Sidel, Cermex, Fujiseal) without custom integration. PackGuru's PackML integration →
OEE — Overall Equipment Effectiveness
Availability × Performance × Quality. The headline manufacturing KPI. World-class lines run above 85%. Many cosmetics filling and capping lines run between 45–65%, with the gap hidden in micro-stops, speed loss, and changeover slowdowns. How PackGuru measures OEE →
OPC-UA
Open Platform Communications Unified Architecture. The modern industrial protocol for secure, vendor-neutral data exchange between PLCs, SCADA, and analytics. Replaces the older OPC Classic (DCOM-based) with a TCP-based, encrypted, cross-platform standard.
MES — Manufacturing Execution System
The software layer between ERP and the shop floor. Tracks work orders, materials, labour, and quality in real time. Traditional MES is heavy and slow to deploy; AI-native platforms like PackGuru deliver MES-grade visibility without 18-month implementations.
4M — Root-cause framework
Man, Machine, Method, Material. A lean classification used to bucket production losses by root cause. PackGuru tags every detected loss against 4M automatically and surfaces the dominant category each shift. PackGuru's 4M analytics →
MTBF & MTTR
Mean Time Between Failures — average uptime between unplanned stops. Mean Time To Repair — average recovery time after a stop. Both are reliability metrics; predictive maintenance aims to extend MTBF and shorten MTTR.
OMAC
Organization for Machine Automation and Control. Industry working group that publishes packaging machinery standards, including PackML and PackTags. Most modern packaging OEMs ship machines with PackML support out of the box.
Sparkplug B
An MQTT specification for industrial IoT. Adds stateful messaging, birth/death certificates, and a defined payload format. Common in modern Industry 4.0 stacks where MQTT brokers aggregate edge data.
MQTT
Message Queuing Telemetry Transport. Lightweight publish/subscribe protocol designed for low-bandwidth, high-latency networks. The default messaging layer for industrial IoT and edge-to-cloud telemetry.
Modbus
A serial protocol (RTU) and TCP variant. One of the most common legacy protocols on packaging lines — older PLCs, drives, and weighing systems still speak Modbus. PackGuru's edge gateway handles Modbus alongside OPC-UA and MQTT.
Golden Recipe
The reference parameters that produced your best-known performance for a given SKU. When today's run underperforms, the golden recipe is the diff target — every parameter difference between now and the last high-performance configuration is a candidate root cause.
Changeover
Switching a line from one SKU to another. Includes format changes, recipe loads, cleaning, and re-validation. SMED (Single-Minute Exchange of Die) targets sub-10-minute changeovers. Changeover time is one of the highest-leverage areas for OEE improvement on multi-SKU cosmetics lines.
Speed Loss
The difference between nominal design speed and actual running speed. Often invisible without high-resolution monitoring. A line rated at 12,000 b/hr running at 9,500 b/hr without any logged downtime is bleeding 17 minutes of speed loss per hour.
Micro-stop
An unplanned stoppage under 5 minutes. Doesn't trigger formal downtime logging in most systems. A line with 30 micro-stops per shift loses more than a single 90-minute breakdown — but it's invisible in the daily report unless something is monitoring at second-level resolution.
ISA/IEC 62443
The international standard for industrial cybersecurity. Defines security requirements across components, systems, and network zones in OT environments. Required by most enterprise procurement teams for any platform that touches the production network. PackGuru's ISA/IEC 62443 architecture →
EU AI Act
European Union regulation on artificial intelligence. High-risk system requirements come into force August 2026. AI systems used in regulated production environments fall under high-risk obligations: audit trails, data lineage, human oversight, traceability. PackGuru is engineered against these requirements from the architecture up. PackGuru EU AI Act readiness →
