Automation commonly refers to the use of hardware, software, and control logic to perform tasks with reduced or no continuous human intervention. In industrial and manufacturing environments, this includes using control systems, sensors, and software to execute repeatable operations, enforce process rules, and coordinate equipment.
Automation in manufacturing and regulated operations
In manufacturing, automation typically involves:
- Physical equipment control, such as programmable logic controllers (PLCs), distributed control systems (DCS), and robotics that run machines, valves, drives, and conveyors.
- Procedural or batch control, where systems execute ordered sequences of operations, often modeled using standards such as ISA‑88 for batch processes.
- Information and workflow automation, such as MES or ERP-driven workflows that generate work orders, collect data, enforce checklists, and trigger quality or maintenance actions.
- Data collection and monitoring, including automated capture of process parameters, alarms, events, and electronic records for analysis and compliance.
Automation can be applied at multiple levels, from a single machine or unit operation, to a production line, plant, or enterprise-wide processes. It can support production, quality, maintenance, supply chain, and regulatory recordkeeping activities.
What automation is not
- It is not inherently a guarantee of product quality, safety, or regulatory compliance. These depend on how automation is designed, validated, and operated.
- It is not limited to robotics or physical equipment; business rules, approvals, and data flows can also be automated.
- It is not the same as full autonomy. Human operators, engineers, and quality personnel typically retain responsibility for oversight, setpoints, recipes, and deviation handling.
Operational usage
In day-to-day operations, automation appears as:
- Automatic execution of recipes or procedures, with control systems stepping through phases and operations.
- Automatic enforcement of interlocks, limits, and preconditions before equipment can start or change state.
- Automated triggering of electronic records, electronic signatures, or quality checks based on process events.
- Scheduled or event-based jobs, such as automatic data exports, report generation, or system-to-system integration tasks.
In regulated environments, the design and modification of automation are typically subject to change control, documented requirements, testing, and periodic review.
Common confusion
- Automation vs. control: “Control” often refers to the real-time regulation of process variables (such as temperature or flow). “Automation” usually includes control but also covers higher-level sequencing, interlocks, and information workflows.
- Automation vs. digitalization: Digitalization involves converting information and processes into digital form. Automation specifically focuses on executing tasks and decisions with reduced human intervention, whether or not the broader process is fully digitalized.
- Automation vs. autonomy: Automated systems follow defined logic and rules. Autonomous systems are designed to make higher-level decisions and adapt behavior with less predefined logic, often using advanced analytics or AI.
Relation to ISA-88 and batch control
Within the context of batch manufacturing and standards such as ISA‑88, automation commonly refers to implementing the standard’s procedural and equipment models in control systems and MES. This can include automated execution of unit procedures and operations, recipe management, coordination between equipment modules, and integration of batch records with higher-level IT systems.
