Are you tired of relying on guesswork to manage your machine cabling? Digital twin technology enables you to precisely determine cable lengths early in the process and order preassembled cables confidently. With crystal-clear instructions, your assembly technicians can now easily install machine cables with plug-and-play ease. Thanks to advanced 3D CAD systems, Eplan can fully support the cabling of your machines.
Still Guessing Cable Lengths?
Planning the cables between machines and control cabinets can be a daunting task. Questions such as what cables to use, how to plan them, and how long they should be can make the process tedious. Unfortunately, it is not uncommon for the planning to be carried out without precise specifications, leading to unreliable results and material waste.
Additionally, surprises such as cut outs or drilled holes that are too small can slow down the assembly process if they are not considered during the planning phase. Without accurate 3D prototypes, achieving a uniform appearance for the cabling is nearly impossible.
3D Model of the Machine, Control Cabinet, and Complete Cabling
All this is much easier with the right software! Electrotechnical 3D CAD systems such as Eplan Cable proD make it possible to depict 3D components of machines, the cabling and the associated control cabinets. And it can be accomplished without any training in complex MCAD software. Once the electrical designs are complete, the 3D representation of the cabling can be transferred to a 3D MCAD system.
This allows, for instance, collision checks to be run, and the electrical design team can quickly clear up any issues as needed. The 3D model can also be used as a virtual prototype during ongoing assembly processes.
Digital Twin of Machine Cabling: Advantages for Planning
- Plan and visualize cable routing, drill holes and cut outs
- Determine cable lengths during the planning process
- Order prefabricated cables from the manufacturer long before they will be installed
- Define clear specifications for assembly and clearly depict them
Digital Twin of Machine Cabling: Advantages for Assembly
- 3D model available as a digital prototype for standardized cabling
- Prefabricated cables can easily be connected
- Trouble-free assembly and customer approval
- Reduced material consumption reduces production costs
Increased Productivity via Prefabricated Cables
Designing components and cabling on a 3D model with clear specifications and preassembled cables makes installation simple, even for those with less experience. The digital depiction of your cabling allows for precise material requirements to be determined early on, making it easy to place orders for everything you need.
Additionally, Eplan offers an HTML export feature that allows assembly technicians to see exactly how engineers planned the cables to be installed, ensuring a trouble-free installation process with early problem recognition and avoidance. This results in increased efficiency and higher quality throughout the entire process. According to Eplan Product Manager Germany Lukas Menzel, “Eplan Cable proD fundamentally changes the process of machine cabling and enables the efficient use and installation of prefabricated cables.”
End The Guesswork
One cost driver in machine engineering is field cabling, where cabling often ends up being either too short or too long. Why is that? Because working by trial and error is still too often used these days. Eplan Harness proD software, which was previously used for designing wire harnesses, has now expanded to also include machine field cabling. The digital twin can be used as a 3D module in mechanical construction or be transferred into the electrotechnical project with added cabling information.
Finding the right cables, planning, designing and plotting their routing for assembly? Until now, this has been a very laborious process for electrical design engineers in machine building. Solutions provider EPLAN has now expanded its 3D software Eplan Harness proD to cover the practical requirements for machine field cabling. What’s long been standard in the mechanical environment is now moving into electrical engineering – the digital twin of cabling.
Depicted in EPLAN Harness proD, this unique product data source is usable in manufacturing, assembly, service and maintenance – by combining electrical and mechanical engineering. The common device database for the EPLAN systems ensures an unambiguous source for all the data. One clear advantage in practice is that every designer can work in their own way, each with their own view of the machine in question: mechanical engineering continues working with assemblies and electrical engineering with functions.
Final Thoughts
Machine cabling no longer needs to rely on trial and error. With Eplan Harness proD, manufacturers and design engineers gain an intuitive tool that bridges the gap between mechanical and electrical engineering. By integrating digital twin technology early in the planning process, teams can reduce material waste, avoid costly errors, and significantly accelerate installation and commissioning. From precise cable length calculations to prefabricated assemblies and seamless communication between departments, our software transforms cabling from a bottleneck into a streamlined, strategic advantage. It’s time to move away from guesswork and towards a smarter, more efficient future.
