When working with PLCs (Siemens TIA Portal/STEP 7), I noticed that some DBs display their name in green text at the top (e.g., "DB_1" in green), while others don’t. - What does this green text mean? - Is it related to addressing, optimization, or something else? - Which type is preferred in practice? If you have experience or tips about this, I’d love to hear them!
