Extrusion International USA 3-2020

9 Extrusion International 3/2020 On 6th April 2020, the State Council of China issued the circular of “The Further Control and Preventive Mea- sures of the Novel Coronavirus at Key Venues, Units and Groups”. According to “Preventive Suggestions” in the circular, it has clearly mentioned that all kinds of exhibi- tions have to be stopped for the time being. Under such circumstances, the 34th CHINAPLAS cannot be held as scheduled and will be further postponed from 3-6 August 2020 to 13-16 April 2021, and the show venue will be changed from National Exhibition and Convention Center in Shanghai to Shenzhen World Exhibition and Convention Center in Shenzhen. As an important manufacturing and R&D center for inno- vative technology in China, Shenzhen has been chosen by the Chinese government as one of the driving engines in the future development of the Greater Bay Area. In shift- ing the 34th CHINAPLAS to Shenzhen, it will enable glob- al plastics and rubber suppliers to tap into the emerging business opportunities in tandem with the further open- ing up of the China market. Postponement and Venue Change of the 34th Chinaplas Adsale Exhibition Services Limited www.ChinaplasOnline.com https://opcfoundation.org/developer-tools/specifications- opc-ua-information-models/opc-ua-for-plastics-and- rubber-machinery/ http://www.euromap.org/i40/euromap-interfaces/ https://opcua.vdma.org/companion-specifications In 2019, EUROMAP and the OPC Foundation have estab- lished the Joint Working Group “OPC UA Plastics and Rub- ber Machinery”. The aim of the international group is to develop worldwide standardized interfaces for plastics and rubber machines based on OPC UA. The existing EUROMAP recommendations EUROMAP 77 (data exchange between injection moulding machines and MES), 82.1 (temperature control devices) and 83 (general definitions) have now been published under the neutral umbrella of the OPC Founda- tion as OPC 40077, 40082-1 and 40083. The most important change is that the so-called namespace, which defines the globally unique identification of an interface standard, has been transferred from euromap.org to opcfoundation. org. This paves the way for the adoption of the standard in other regions such as Asia and America. Even if the stan- dard is translated into national adoptions and, if necessary, assigned a different local number, the uniform namespace ensures that the data to be exchanged is uniform and is rec- ognized by the connected devices. In addition, a new series for extrusion, OPC 40084, has been published. It considers the extrusion line as a whole with its production status and order management as well as the individual components with status and process values. Cur- rently the different parts cover extruders, haul-offs, melt pumps, filters, dies, pelletizing, cutter, calibration and cor- rugators. Further parts for components such as calenders, splitting and winding will follow. The use of standardized digital data exchange facilitates the commissioning and op- eration of the extrusion line.
