The Factory Acceptance Test: An Integral Part of the Engineering Process<\/h2>\n

In automation technology, the Factory Acceptance Test (FAT) is a fixed component of the engineering process. Manufacturers of machines set them up in their own workshops and commission the control technology components. Before the machine is finally delivered to the customer, the customer visits the manufacturer and in a joint meeting the functionality of the machine is approved by the customer. In this Factory Acceptance Test (FAT) the entire range of functions of the machine is examined. Modification requests of the customer are documented and subsequently implemented by the machine manufacturer. Only then is the machine delivered to the customer, assembled and commissioned.[\/vc_column_text]

The Limitations of the Factory Acceptance Test<\/h2>\n

The factory acceptance test is an important milestone for both the machine manufacturer and the customer. After the Factory Acceptance Test has been passed – if you like to put it that way – the machine can be delivered to the customer. It would therefore make sense to test the entire functionality of the machine during the acceptance test. To understand that this requirement cannot always be met, imagine for example a large conveyor system: To completely assemble this in the workshops of the machine manufacturer is usually simply not possible due to a lack of space. Another example would be a machine that processes heavy or expensive components: Handling them during the Factory Acceptance Test would be very time-consuming. So in practice, only individual sub-functions are assessed during an FAT. The functionality of the entire machine can only be tested after commissioning at the end customer’s premises. Subsequent modifications to functions or even defects must then be added and repaired at the end customer’s facility. I am convinced that every machine manufacturer can confirm that efficiency, quality and ultimately costs are affected by this.[\/vc_column_text]

The Digitalization of the Factory Acceptance Test<\/h2>\n

So what can we do to improve this important milestone? The aim would be to examine the entire functionality of the machine together with the customer. Maybe even before expensive mechanics are built – who knows, maybe there will be changes later? It would be desirable if, for example, products could be manipulated as required during the factory acceptance test or scenarios such as operator access or malfunctions could be tested.<\/p>\n

This is where the digital twin enters the stage. The digital twin in 3D is the digital counterpart of the real machine. The digital twin has already been used for virtual commissioning – this word should actually be banned, but that’s another matter. The technicians develop and test control software, robot programs, control systems and HMIs on the digital twin. As if the real machine were standing on their desk. This means that the entire functionality of the machine is developed and tested on the digital twin. And this is exactly what the customer wants to see in the Factory Acceptance Test. Usually very difficult to achieve in reality. And digitally? No problem![\/vc_column_text]

There’s No Such Thing as Digital Pain<\/h2>\n

The digitalization of the Factory Acceptance Test brings enormous advantages. Since the digital machine behaves exactly like the real machine and is not only controlled by the real controller but is also operated by the real control system or HMI, the customer can explore the machine and inspect its functionality. All in a secure, virtual environment. The real machine is not needed for this. There are no space constraints, no risk of damage, products can be manipulated freely, and cycle times, access, and disruptions can be tested without concern. The digital machine is operated with the real HMI or control system. This means that the function as well as the usability of the latter are also approved at the same time. Modification requests that arise during the Factory Acceptance Test can be better planned and implemented early on.[\/vc_column_text]

The control system of the machine can be seen on the screen at the rear right. The digital twin of the machine, the machine itself, is located in the middle. During the virtual FAT, we were able to run through situations with the customer that would never have been possible in a real factory acceptance test. We proved cycle times, were able to show that the machine can make up for production backlogs after malfunctions and were able to go through various work processes with the system operators.[\/vc_column_text][\/vc_column][\/vc_row][vc_row heading_color=”light” bg_type=”color” padding_top_multiplier=”4x” padding_bottom_multiplier=”4x” font_color=”#ffffff” margin_bottom=”0″ bg_color=”#0a3b61″][vc_column css=”.vc_custom_1588863781753{padding-top: 0px !important;padding-bottom: 0px !important;}”][vc_row_inner css=”.vc_custom_1588162622076{padding-top: 0px !important;padding-bottom: 0px !important;}”][vc_column_inner width=”1\/2″ tablet_sm_width=”11-12″]
