Nestfield developed an AAS-based pilot plant with the support of the Korean Ministry of SMEs and Startups and KOSMO (Korea Smart Manufacturing Office).
During the 1st stage of the Pilot Plant Project (PPP) in 2020 an AAS-based data acquisition and storage system was developed and successfully installed in two pilot plants, i.e., Shinwoo Costec and Huons.
In the 2nd stage of the PPP we plan to expand the development of AAS-based standard technologies to the entire life cycle of the production process, including commissioning, operation, management, prediction, decision-marking, control, etc.
We have held an online forum to share the current status and future cooperation between Korea and Germany on the development, testing and utilization of AAS standard technologies.
A joint Korea-Germany live stream session was held at the Hannover Online Exhibition in April 2021. AAS experts from Korea and Germany came together in the Nestfield live stream session and they introduced AAS technology-related activities and AAS technologies being carried out in Korea and Germany.
An AAS-based Tenderiong Testbed was located in both Nestfield and LNI booths at the Hannover Exhibition in June 2022, representing the technology exchange between Korea & Germany.
Visitors were able to freely configure the preferred text (Korean / German / English) on the souvenir (i.e., pen) according to the “Tendering” guideline.
5G is an emerging technology in the industry. Nestfield focuses on industrial private 5G technology especially in MEC (Multi-access Edge Computing).
As part of the Private 5G (e-Um 5G), a 5G test bed was built on CTR's ball joint line.
Out of around 60 production lines, the Ball Joint line which consists of 13 sub-processes and the AMR are connected through a Private 5G.
In order to easily manage Private 5G, we implemented and demonstrated a USE CASE by modeling Private 5G as AAS digital twins.
The opening ceremony was arranged to celebrate the first factory in Korea that demonstrated manufacturing services based on Private 5G in the real manufacturing process.
Nestfield has developed an AAS-based PnP testbed (with three robots and one turntable) to implement an I4.0 scenario of Plug-and-Produce (i.e., a representative use case of adaptable factories).
OPC UA/TSN technologies were implemented to realize the interoperability between different assets.
Orienting for the Industry 4.0-based smart manufacturing system, we have developed a refined TSN-integrated architecture referencing the network model of IEEE Std Qcc.
We have also developed a scheduling algorithm which was applied to the Centralized Network Configurator (CNC), and also configured High-Load and Low-Load scenarios to compare the QoS of scheduled traffic (robot control) and unscheduled traffic (video display).
The two operation scenarios verified that the developed TSN system can satisfy the real-time requirements and is robust enough even under the high-load traffic scenario.
