Interview Questions for EPLAN

In EPLAN, a project is the overarching container for your entire engineering design. Think of it as the blueprint for a complete system – it holds all the schematics, reports, PLC I/O assignments, and other related data for a specific project, such as a control panel for a factory machine. A macro, on the other hand, is a reusable component. It’s like a pre-fabricated module – a collection of already-designed parts and connections that you can insert multiple times into your project. For example, you might create a macro for a standard motor starter circuit, which you can then easily add to different locations within your project instead of repeatedly drawing the same components and connections.

Consider building a house: the project is the entire house plan encompassing all rooms, electrical, plumbing etc. A macro would be a pre-designed kitchen module that you insert into the project. You don’t redraw the kitchen every time; you simply reuse the module.

EPLAN doesn’t have built-in version control like Git. However, we can effectively manage versions using external version control systems (VCS) or by leveraging EPLAN’s project management features and file-saving practices.

• External VCS (Recommended): I prefer integrating EPLAN with a system like Git, SVN, or similar. This allows me to track changes, revert to previous versions, and collaborate with team members seamlessly. The entire project folder, including all EPLAN files, can be managed within the VCS.
• EPLAN’s Project Management: EPLAN allows for creating project backups and creating different project copies with specific naming conventions (e.g., ProjectName_v1.0, ProjectName_v2.0). This offers a simpler approach for smaller teams or projects but lacks the sophisticated branching and merging capabilities of a dedicated VCS.
• Regular Backups: Regardless of the chosen method, regular backups are crucial. I recommend daily backups to a separate location to prevent data loss due to hardware failure or accidental deletion.

I’m highly proficient in utilizing EPLAN’s schematic creation tools. My experience encompasses creating complex schematics for various industrial automation projects. I’m comfortable using functions like:
