Programmable Logic Controllers
PLCs (Programmable Logic Controllers) are digital industrial computers. They are widely used by electrical…
What is the role of a PLC?
Schneider Electric and Siemens PLCs are designed to run complex computer programmes that manage the synchronisation of the inputs/outputs required for machines to operate correctly. PLCs process input data from a variety of sensors, and control outputs to actuators.
What is a PLC in industry?
The integration of Schneider Electric or Siemens PLCs in industrial installations offers many advantages in the automated management of control systems. PLCs will improve operational efficiency and reduce production costs by minimising human error, while optimising the use of all resources. In industry, for example, PLCs will be programmed to establish perfect synchronisation of the various production stages, reducing downtime and increasing productivity. Another example of automation is the integration of PLCs in transport systems; always at the service of performance, they are a real asset in guaranteeing the reliable and consistent movement of materials.
SCADA: a technology at the service of programmable logic controllers
Modern PLCs from Schneider Electric and Siemens integrate with wider systems, such as SCADA (Supervisory Control and Data Acquisition) systems. A SCADA system is a software platform for large-scale monitoring, control and data processing. In complex industrial processes, it acts as an interface between field equipment (machines) and human operators. In industrial environments, these systems, which are integrated with programmable logic controllers, enable optimum management of resources and rapid decision-making. SCADA systems therefore help to improve production performance while reducing maintenance costs and extending the life of industrial equipment.
Current trends in PLCs
Current trends in programmable logic controllers (PLCs) are heavily influenced by Industry 4.0 and the Industrial Internet of Things (IIoT). Over time, modern PLCs are integrating more and more sensors and IIoT devices to enable them to make autonomous decisions and continuously improve processes (Schneider Electric's EcoStruxure Machine Expert range, Siemens' SIMATIC solutions). These developments are helping manufacturers to collect and process quality data in real time, right up to the implementation of predictive maintenance models. However, there is one point to bear in mind: the increase in Ethernet-based network connections in industrial environments means that high levels of security are required. Manufacturers are increasingly investing in cybersecurity solutions to protect systems against cyber attacks.
Programmable logic controllers: what impact on industrial production?
Programmable logic controllers from Schneider Electric and Siemens have a major impact on industrial production. They are essential for transforming industries into modern, efficient and competitive entities. Increased productivity is made possible by automating repetitive tasks and reducing potential errors that can occur during production. They offer advanced automation solutions that adapt to the changing needs of businesses. By keeping abreast of the latest trends and technologies, electrical professionals can make the most of PLC capabilities to optimise operations and stay at the forefront of industrial automation.
