Continental sought an update to their process analysis and control systems for their passenger car, light truck, bus and truck tire production sites, within 18 separate locations worldwide. The company’s initial aim was to develop a system that could handle near real-time data collection from production equipment for process and product analysis and optimization. Thus, “DOPAC” was born.
DOPAC was the internal project name initiated by Continental, standing for its planned “Database for Online Process Analysis and Control”. A pilot project began in 2016 in the company’s Puchov, Slovakia plant, with a year spent on prototype development. Continental decided early in the process to move on from installed legacy systems and, after considering multiple vendor solutions, decided upon GENESIS64 HMI/SCADA and Hyper Historian data historian to comprise the heart of DOPAC.
Continental’s new system was intended to steer and continuously improve the company’s production processes based on statistical process control (SPC) measurement of product performance-relevant data. A taskforce was put together to clearly define the company’s IT requirements, as the right pertinent performance data was deemed necessary for continuous improvement. On top actual product and process data were for intended advanced analytics.
During the pilot phase, Continental prioritized its expected core functionalities for their new system. High on the list was real-time data collection. Another necessity was a redundant architecture, including data buffering at sources. The company also highly valued integrating specification systems, high-rate data compression and data mapping.
Next on the company’s list of priorities was process analysis. Their selected system needed to include a mechanism for decision and escalation workflow, as well as for SPC online. Rounding out Continental’s core functionality priorities were dashboarding and archiving abilities. At the end of Continental’s pilot project, DOPAC will be installed in two locations on more than ten pilot machines in each facility. The company continues to validate DOPAC’s business use case through the performance of defined technical test cases. When finalized, the system will be expected to work with multiple brands of PLCs, handle initial groups of sensors/tags defined by central functions, and an interface with the company’s current MES systems.
