End-User Dynamics And Use Case

PLC adoption looks different depending on who’s using it—and why. From high-volume auto plants to small food processors, each end user brings unique expectations and constraints. What unifies them is the need for reliable, repeatable control in increasingly complex environments.

1. Manufacturing (Automotive, Electronics, FMCG)

This is the core driver of global PLC demand. Automotive plants rely on PLCs to coordinate robotic arms, conveyor systems, painting booths, and engine assembly. In electronics, precision timing and motion control are key, especially in PCB assembly and packaging lines.

These environments typically favor modular PLCs with fast response times, hot-swappable I/O, and remote diagnostics. Leading OEMs now demand cyber-hardened PLCs with SCADA integration to meet strict uptime and safety thresholds.

One plant manager at an EV battery facility put it bluntly: “If the PLCs aren’t reliable, we’re losing six figures a day.”

 

2. Energy and Utilities

Here, PLCs play a different role—less about speed, more about safety and scalability. Think water treatment facilities, substation automation, wind turbine controls, and oil & gas flow systems.

Utilities prioritize redundancy, long lifecycle support, and secure remote access . In regions with smart grid rollouts, PLCs are being paired with telemetry systems to manage power loads, detect faults, and integrate renewables in real time.

 

3. Oil & Gas and Chemical Processing

These are harsh, high-risk environments. PLCs in these settings are often part of emergency shutdown (ESD) and process safety systems (PSS) , where failure is not an option.

Redundancy, SIL-rated logic modules (Safety Integrity Level), and hazardous area certifications are non-negotiable. Some installations use triple-redundant PLCs , particularly in upstream offshore rigs or refineries.

 

4. Water & Wastewater Management

Municipal and industrial water systems are rapidly digitizing, and PLCs are a key part of that. They control pumps, monitor tank levels, manage filtration cycles, and respond to SCADA signals.

These facilities often work with limited IT support , so user-friendly PLCs with remote diagnostics and long service life are in demand. Many municipalities in Asia and Latin America are skipping older control systems altogether and going straight to smart PLC setups.

 

5. Building Automation and Smart Infrastructure

In airports, hospitals, and commercial buildings, PLCs now control HVAC, elevators, fire suppression, and lighting. These systems must integrate with BMS (Building Management Systems) and often run 24/7.

Here, vendors compete on ease of integration, energy monitoring , and compact designs that can fit into space-constrained control panels.

 

Use Case Highlight

A regional airport in Southeast Asia was facing rising energy costs and unreliable HVAC performance. Their old system lacked centralized control, leading to overcooling and constant maintenance issues.

The facility deployed a network of compact PLCs from Schneider Electric across its chillers, air handlers, and lighting systems. Each PLC was connected to a cloud-enabled BMS dashboard with predictive maintenance alerts.

Within six months, the airport reduced energy consumption by 17% , cut HVAC downtime by 60% , and improved passenger comfort scores.

That one retrofit project paid for itself in under a year—and led to the same setup being rolled out at two nearby railway terminals.
