Worlds of Industrial Automation and Process Control Begin to Merge 

By November 18, 2017Product News

One huge potential benefit of the current push to new industrial communication standards, driven by the Industrial Internet of Things and Industry 4.0’s smart manufacturing initiatives, is open, secure, interoperable architectures that integrate solutions that address both discrete and process automation. These worlds of industrial automation and process control have largely been apart in the past but now, with the need to achieve much tighter integration with business systems and the supply chain, there is a new push for solutions that will enable a gradual merging of these two worlds based on common standards.

Process vs. Discrete Automation

For process automation companies, there are emerging possibilities for controls optimization by implementing a universal platform that covers both industrial automation and process automation using PC-based control.

New offerings from Beckhoff, for example, move in this direction by integrating process-specific protocols and interfaces, and by offering an extended range of products for hazardous areas including full implementation of HART functionality. By providing connectivity using process technology protocols such as HART, NAMUR, and FDT/DTM, and integrating these protocols and programming standards into its TwinCAT software development environment, this approach provides a familiar experience for users who previously worked with other software environments. The TwinCAT FDT (Field Device Tool) container can enable implementation of any field device drivers (Device Type Manager, DTM), so an entire HART configuration can be implemented efficiently using a single tool.

The system also provides a CommDTM for communicating with existing process control systems, as the DTMs can be implemented in any FDT container. This applies to all field devices connected to HART-capable EtherCAT Terminals. Devices can also be configured and parameterized remotely in known containers without requiring direct PLC access. OPC UA server and client functionality creates a method for secure global distribution of process data, as well as system control and remote maintenance capabilities.
