Industrial closed-loop control technology

Closed-loop control technology

A flexible learning platform that brings the factory system directly to the laboratory

The numerous and varied process automation requirements that industry has to master need highly qualified, specialised personnel who need to be trained far beyond the mere basics. Since it is prohibitively expensive to switch off an industrial system or to build a real, functional system exclusively for teaching purposes, there is a need for learning platforms that represent the industry as realistically as possible.

Precisely tailored to industrial requirements

Very few learning systems for process automation are truly industry-oriented yet also flexible enough to be suitable for educational, training and research purposes. Our learning solutions for industrial closed-loop control technology are one of these rare industry-oriented AND flexible offers.

The learning concept for this system series is based on a combination of detailed courseware covering the entire area and industry-class equipment in accordance with industry standards.

Fully modular for maximum versatility

The solutions are modular so specialists can adapt them precisely to the learning requirements in a wide range of contexts, without the need for too much equipment. This will enable them to train young employees in process automation and to update or expand the skills of experienced employees, and even to support research and development activities.

There are a number of configurations available for the systems. Optional equipment further expands the range of options. Thanks to this flexibility, the learning systems can be gradually expanded to cover the further development of technologies and processes.

Tailored to the needs of a wide range of learners

Our closed-loop control training program is suitable for operators, mechanics, control, electronics and process technicians, mechanical engineers, chemical engineers, electrical engineers and electronics engineers as well as other professionals, such as software developers who need sound knowledge of the main processes and equipment used in the industry. The hardware can also be used, for example, in research projects on cyber security or in new, modern control algorithms (control of artificial neural networks).

The benefits to you

Modular hardware set-up

Our learning systems are equipped with two double-sided mobile workstations that are linked together with a hitch mechanism:

  • The process workstationis the central point for the processes that the students examine, and contains pumps, lines, valves, boilers and all other components belonging to the circuits.
  • A control workstationcontains the electric and pneumatic units and other electric devices, including adjustable drives, controllers, PLCs, colour paperless recorders and touchscreen graphic terminals.

This recreates the widespread industrial practice of separating the process environment from the instruments and controllers and limiting the risk of these devices coming into contact with water.

Turnkey complete-Courseware

The learning solutions are part of the closed-loop control technology program, which uses modern equipment and a comprehensive syllabus to provide students with the necessary theoretical and practical knowledge to work in closed-loop control technology.

During the course, the students first familiarise themselves with the learning system and then continue with the measurement followed by basic and advanced closed-loop control technology. Specific instructions or manuals are also available for a large number of components, so that all devices are well documented.

The theory is explained clearly and simply. The practical tests are described in detail and illustrated in order to facilitate independent learning.

This complete learning program provides comprehensive training and thus an increased return on investment and better preparation for the workplace.

Intelligent: HART/FOUNDATION fieldbus

Many system components are equipped with a transmitter that communicates via the HART or FOUNDATION fieldbus protocol.

  • With the HART protocol, the devices communicate with digital signals that are superimposed on the existing 4 to 20 mA outputs.
  • The fieldbus protocol works like a local area network (LAN) for intelligent devices.

Most of these devices can usually be configured manually via an alphanumeric display and/or keys or via a remote computer. Calibration kits are available for each protocol.

Well-known brands

The systems are equipped with a wide range of sensors, transmitters and controllers from well-known brands such as Honeywell, Endress+Hauser, Rockwell Automation, Fisher and Foxboro. This means that learning is based on industry standards, and the actual processes can be easily replicated for teaching purposes.

Software support

The following software programs are available for successful laboratory tests and an accurate understanding of the processes:

  • The SCADA software programs, Wonderware Development Studio (including InTouch) and FactoryTalk View Studio (from Rockwell Software) are equipped with an interface specifically designed for learning systems for pressure, flow rate, level and temperature processes. An OPC server for the Foxboro controller is also available.
  • With the free LVProSim simulation software, various process control schemes can be simulated and data acquisition and PID control of a real process can be managed.

Development of troubleshooting skills

Troubleshooting for industrial process devices should be an integral part of training. Our learning systems include a wide range of tools that experts can use to easily plan troubleshooting tasks for students. Errors can be inserted into most devices such as controllers, PLCs, transmitters, etc. using various methods.

Pressure, flow rate, level and temperature processes

The learning systems for pressure, flow rate, level and temperature processes introduce students to a wide range of industrial processes with the appropriate instruments, controllers and troubleshooting procedures.

The system also provides knowledge on complex control strategies, for example for controlling a boiler level. The students can apply various advanced control strategies to the boiler simulation, including split-range, ratio and feedforward control.
