digital twin: who are you? and why?

Design phase often involves costly erring between unfinished drawings, incomplete tools and production plants under construction. The digital twin can point the way. But who or what is it and in which case is its help useful? We will tell you!

“Oh brother… ähm twin, where art thou?” sounds familiar to you. But what does the reference to Shakespeare's “Romeo & Juliet” or to the Mississippi Odyssey from the eponymous film have to do with digital twin technology? Well, because the status of the journey of the “digital twin” or “digital shadow” has not yet been fully clarified even among experts. No?

Digital twin - Who are you?

In the planning phase of a project, the schedule is often tight, and at the same time, the required data is often not complete. Virtual startup and the generation of a digital twin can make sense in this phase. The digital twin is the virtual image of a cell or an entire production plant including its tools and parts.

Digital twin - Why are you?

The digital twin can be used to simulate the relationships in the process and material flow as well as to identify and correct possible errors for virtual commissioning, deviations and problems, before the system really starts running. This prevents time-consuming and costly downtimes and material losses. At the same time, the operator can check the progress status of the supplier.

Digital twin - Where are you?

The status and location of the plant are not decisive. Commissioning does not have to take place on the construction site with real hardware, but can be carried out on the computer.

Digital twin or hardware?

In the case of complex and interlinked systems or when using non-standard equipment and new software, the digital twin is the method of choice. Since a kinematized model is used for this, which, however, reproduces sensors and actuators but not tools, the test of the control software is of primary importance.
