Programmable PLC / HMI controllers

PLC/HMI Programmable Logic Controllers - the heart of modern automation

PLC/HMI programmable logic controllers are key elements of modern industrial automation systems.   At Onninen we offer a wide selection of these advanced devices. Our portfolio includes solutions from leading manufacturers. These are the Eaton, Elcon and Schneider Electric brands. Each of them has unique features and applications.

PLCs (Programmable Logic Controllers) are the brains of automation systems. They manage production processes in factories. They control assembly lines and industrial machines. In turn, HMIs (Human-Machine Interfaces) are operator interfaces. They enable communication between humans and machines.

In our daily practice, we see a growing demand for these devices. Customers are looking for flexible and scalable solutions.   PLC/HMI controllers perfectly meet these requirements.   They enable easy expansion and modification of automation systems.

Types of PLC/HMI controllers available at Onninen

Our offer includes various types of PLC/HMI controllers. Here are the most popular types:

• Compact PLCs - ideal for small applications
• Modular PLC controllers - flexible and scalable
• HMI operator panels - with touch screens or buttons
• Integrated PLC+HMI systems - all in one device

Each type has its advantages and optimal applications. Compact PLCs work well in simpler systems. Modular ones offer greater expansion possibilities. HMI panels vary in size and functionality. Integrated systems save space and cabling.

When selecting a PLC/HMI controller, the specific requirements of the application are crucial.   We analyze the number of inputs/outputs, type of signals, required computing power. We take into account the work environment and communication needs. We also advise on the user interface and process visualization.

Key Features of PLC/HMI Programmable Logic Controllers

Modern PLC/HMI controllers offer a number of advanced features. Here are the most important ones:

• Modular design for easy expansion
• Support for various communication protocols
• Advanced Math and Analytical Functions
• Possibility of programming in multiple languages (LAD, FBD, ST)
• Built-in security and diagnostics

These controllers often have built-in web servers. This allows remote access and monitoring. Increasingly, they also offer cloud and data analytics functions.   These are key elements in the context of Industry 4.0 and IIoT.

In the case of HMI, the following are important: screen resolution, number of colors, brightness. Resistance to harsh industrial conditions is also important. Some models offer a degree of protection of IP65 or higher. This allows work in dusty or humid environments.

Our experience shows that customers value intuitive operation. That is why we recommend solutions with user-friendly graphical interfaces. They facilitate the configuration and programming of automation systems.

Practical applications of PLC/HMI programmable logic controllers

PLC/HMI controllers are used in almost every industry.   Here are some examples from our practice:

In the food industry, PLCs control production lines. They manage temperature, pressure, flows. HMIs allow operators to view and control processes. Recently, we used the Schneider Electric system in a project for a large beverage manufacturer. This allowed us to optimize processes and increase efficiency.

In the automotive industry, PLC/HMI controllers are the heart of assembly lines. They coordinate the work of robots, vision systems, and conveyors. One of our clients automated the production of car seats in this way. The effect was an increase in quality and a reduction in costs.

These controllers also work well in building systems. They manage lighting, air conditioning, and access control. In the case of office reorganization, it is usually enough to reprogram the system. This saves time and money compared to traditional installation.

Many customers ask us about the possibilities of integrating older machines with new systems.   This is where PLC controllers with a wide range of interfaces come in handy. They allow communication between devices of different generations. This is an ideal solution for the gradual modernization of the machine park.

We often come across the question of redundant systems. In critical applications, such as sewage treatment plants or power plants, we use duplicated PLC controllers. They ensure continuity of operation even in the event of a failure of one of the devices.

In the context of Industry 4.0, PLC/HMI controllers act as IoT gateways. They collect data from sensors and transmit it to analytical systems. This enables predictive maintenance and process optimization. We implemented such a system for one of our clients from the packaging industry. This allowed for a 30% reduction in unplanned downtime.

Onninen recommends the use of PLC/HMI controllers in fire protection systems.   Our solutions include special boards for these applications. They provide the highest level of safety and reliability. In combination with the appropriate I/O modules, they create a complete protection system.

In agriculture and horticulture, PLCs control irrigation systems. They manage drip lines, adjusting irrigation to conditions. HMIs allow easy programming of schedules and monitoring of soil moisture.

Our customers in the energy industry use PLCs to manage Smart Grid networks. They coordinate the work of distributed energy sources and optimize distribution. This is a key element in the energy transformation.

In logistics, PLC/HMI controllers are the heart of automated warehouses. They control sorting systems, conveyors, palletizing robots. For one of our clients, we implemented a PLC-controlled labeling system. This increased the accuracy and speed of order picking.

Our experience shows that the investment in PLC/HMI programmable logic controllers pays off quickly.   It translates into increased efficiency, reduced errors and energy savings. These are the foundations of modern, competitive production.

At Onninen we offer not only the devices themselves, but also comprehensive support. Our engineers advise on the selection of optimal solutions. We provide training in programming and operation of PLC/HMI controllers. We also offer system integration services and after-sales support.
