VDMA 40740 interface for process air extraction and filtration systems published

In the digital production world, machines from different manufacturers must be able to communicate with each other. This requires uniform standards - so-called OPC UA Companion Specifications - in the development of which the VDMA is significantly involved. VDMA 40740 is currently published in the series of Companion Specifications and depicts universal, manufacturer-independent interfaces based on OPC UA. The UA Information Model for Process Air Extraction and Filtration Systems (PAEFS) was developed by the VDMA working group "OPC UA Air Pollution Control" together with the OPC Foundation working group "Process Air Extraction and Filtration Systems - PAEFS". "The aim of the model is to map a standardized interface for exchanging data between process air extraction and filtration systems. Furthermore, also to upstream machines and to supporting systems, such as technical ventilation and conveying systems," reports Christine Montigny, VDMA General Air Technology.

"The aim is also to present a standardized interface in higher-level production systems, such as Manufacturing Execution System (MES), in a manufacturer- and platform-independent communication network," adds Montigny, who provided internal support for the VDMA project. MES describes a system in operational production management that supports production planning and control. It provides a digital image of production and enables real-time monitoring of production processes. PAEFS are significant systems that can be used in the process industry and the manufacturing industry. An elementary task of PAEFS in operational process air technology is the fulfillment of basic functions. This includes supplying a process with the required air, creating an air condition necessary for operation, and detecting substances released in the process. The VDMA Specification 40740 "OPC UA for Process Air Extraction and Filtration Systems (PAEFS)" is now available for download.
