network – such as pipe lengths – can be overlaid on a map. Molecor components can be added and geolocated automatically by scanning a QR code; other components can be entered manually. Images and information can also be added
about each component. Incidents can be reported directly from the app, to pinpoint its location. The app, which was introduced at K2022, is available in multiple languages.
Keep talking Thorsten Kühmann, managing director of VDMA Plastics and Rubber Machinery, told delegates at K2022 that machines must increasingly communi- cate with one another – using a ‘global language’ such as OPC UA. At the show, around 40 companies from eight countries were running an OPC UA demonstration project, involving 85 machines. Each had an OPC UA logo and a QR code that visitors could scan with their smartphones. From here, they were taken to the UMATI internet platform, where they could see live data from each machine. “For greater clarity, we installed a large dash-
board in the VDMA Dome – where visitors could navigate each individual machine to see defined data,” said Kühmann. The most important factor, he said, is for “all machines to speak the same language and use the same system”. OPC UA implementation has already happened
for core machinery such as extruders – and is now being extended to areas such as particle foaming and ancillaries, he said. “This includes temperature control units and hot runner units, or liquid silicone metering,” he said. “This is the horizontal level. Machines next to each other in a production hall can communicate with each other.” However, Kühmann said that many processors are still cautious about OPC UA applications.
“They are worried that their data will not be handled carefully – and even that their competitors may gain access to it.” Part of the problem is that these data platforms have only been offered by individual companies or small consortia – which users do not trust. For this reason, VDMA is trying to establish a trustworthy, neutral platform that anybody can use.
Higher functionality Davis-Standard has introduced its DS-XEL control system. The system, which replaces mature discrete
controls, implements high-performance HMI features to meet the data and process information needs of modern manufacturing, says the company. It focuses on active functions for a better operator
experience and improved connectivity, according to the company. The DS-XEL will be the new standard control for Davis-Standard’s Super Blue and HPE extruder lines and is compatible with the DS Activ-Check cloud-based platform. It is also avail- able as an upgrade to existing extruder controls. “This controller merges the latest PLC and HMI
offerings to enable an operator-friendly package with greater attention to detail,” said John Clem- ens, director of extrusion controls at Davis-Stand- ard. “It also incorporates key features only available
