Due to increasing competition, innovative automation solutions which optimize efficiency while taking production quality and safety into account are increasingly in demand in the process industry. The development of new technologies opens up possibilities for optimizing production processes, both for modern new plants and for the retrofitting of existing plants.
Beckhoff offers open automation solutions for the process industry that precisely meet these requirements: PC-based control provides a universal control system that can be used to automate all plants and processes. By consistently bundling control intelligence in the software and using established standard technologies from the IT and automation world, PC-based control combines all functions in a single system. For those working in the process industry, Beckhoff offers a wide range of products to support the implementation of comprehensive solutions for unimpeded communication from zone 0 to the cloud. These include scalable industrial PCs and control panels, I/O modules with intrinsically safe interfaces, TwinCAT automation software featuring specific process technology interfaces along with the relevant hardware and software modules for simple IoT communication, the use of cloud-based services, plant networking, and much more besides. What’s more, current industry standards are covered by embedding process technology-specific interfaces such as NAMUR, HART, and FDT/DTM. System-integrated controller and cable redundancy ensures reliable operation without downtime to increase plant availability.

Explosion protection: Zones and factors
To create an explosion, a combustible mix of oxygen and fuel must get in contact with an ignition source. Explosion protection involves taking measures that prevent explosions by excluding one of these three risk factors. Since many processes use materials that are flammable and create an explosive atmosphere in combination with air, preventing the atmosphere from becoming potentially explosive is often not feasible. This is why hazardous areas must be marked as such in order to ensure that no electrical equipment will be used that can cause an ignition as a result of factors such as sparks or high surface temperatures, for example.
In compliance with European explosion protection regulations, such areas are divided into zones that reflect the degree of the explosion hazard. For gases, the zones are 0, 1, and 2. For dust, they are zones 20, 21, and 22. Zone 0/20 (gas, dust) describes areas in which an explosive atmosphere exists permanently or frequently or for long periods of time. Areas that are occasionally subject to explosion hazards are marked as zone 1/21. Zone 2/22 describes areas in which an explosive atmosphere exists never or only for short periods of time.
With its broad portfolio of components, Beckhoff makes it possible to build integrated explosion protection solutions through to zone 0/20 with EtherCAT Terminals, high-quality control panels and panel PCs, as well as embedded PCs and bus couplers for easy integration with all common fieldbus systems. With Beckhoff, users can implement any explosion protection application involving explosion hazards, including the retrofitting of existing systems.
For use worldwide: the explosion protection portfolio
For systems and equipment in areas exposed to explosion hazards, different standards apply all over the world:
- International explosion protection (IECEx)
- European explosion protection (ATEX)
- North American explosion protection (NEC/CEC)
Country-specific approvals such as IA for South Africa may also be required. Users must make sure that their installations meet applicable guidelines and standards. The Ex component portfolio from Beckhoff meets all listed standards and is certified for the intended use in hazardous areas in compliance with applicable regulations.
As a result, PC-based control makes globally uniform solution concepts possible for barrier-free system integration up to zone 0/20.
Elimination of separate safety barriers: Savings with ELX terminals
The conventional implementation of standard compliant explosion protection involves connecting field devices from zone 0/20 via separate safety barriers. Installing such barriers in the control cabinet, however, requires a relatively high cabling effort and takes up a lot of space. Using highly compact ELX series EtherCAT Terminals eliminates the need for such separate safety barriers, because these I/O modules can be connected directly to intrinsically safe sensors and actuators that are installed in hazardous areas up to zone 0/20. In contrast, the cost and space savings made possible by ELX terminals allow users to build machines and systems that are as compact as they are efficient. The bottom line: the control cabinet space requirements along with costs and effort involved can be reduced significantly.
