Run Two 3D Machines at Once — Multi-Scene PLC Simulator

Run two 3D machines from one program in the ACC PLC Simulator. Learn how address offsets keep each scene in its own block of PLC memory. ⚡ QUICK ANSWER From version 121, the ACC PLC Simulator can run several 3D scenes against a single program. Because every scene ships thinking it owns X1, the simulator hands each connected scene an address offset — a number added to its discrete addresses before your program ever sees them — so the whole rule is one addition: PLC address = scene address + that scene's offset, applied to X and Y separately. Connect a second scene and the allocation is chosen for you and shown in three places, and the scene even relabels its own inputs to match. The worked remote-start example, the contention rules and the exceptions are in the full write-up. 📖 FULL STEP-BY-STEP + DOWNLOADS (project file, wiring diagrams, screenshots) https://accautomation.ca/run-two-3d-machines-at-once-multi-scene-plc-simulator/ 🕹️ TRY IT FREE — THE ACC PLC SIMULATOR https://accautomation.ca/simulator/ ⏱️ TIMESTAMPS 0:00 - Introduction 0:43 - Every Scene Thinks It Is X1 1:06 - Connect Both and They Collide 1:50 - The Fix Is an Address Offset 2:32 - A Worked Allocation: Starter at 0, Panel at 3 3:15 - The Simulator Picks the Offset for You 4:01 - Three Places You See the Offsets 5:02 - Build a Remote Start Station 5:42 - The Program, Rung by Rung — and Running It 7:03 - Contention, Shared Outputs, Analog and Modbus 9:09 - Limits, Performance and Why This Matters 10:35 - Try It Yourself 📚 WHAT YOU'LL LEARN ✅ Give each connected 3D scene its own block of PLC memory using address offsets ✅ Work out any address with one rule: PLC address = scene address + that scene's offset ✅ Let the simulator allocate offsets automatically, or type your own X and Y values per scene card ✅ Read the memory strip to see which scene owns each of the 16 X and 16 Y addresses ✅ Build a remote start station — a motor starter plus a remote control panel — from one program ❓ FREQUENTLY ASKED Q: How do I work out the address for a scene that has been offset? A: Add that scene's offset to the scene address. Apply it to the X addresses and the Y addresses separately, because the two axes are allocated independently. Q: Do analog addresses and Modbus addresses get offset too? A: No. Analog addresses stay exactly where the scene reference lists them, and a scene driven over Modbus from a real PLC is never offset. Q: How many 3D scenes can I run at once? A: The ceiling is 16 X addresses and 16 Y addresses. The palletizer alone takes 10 inputs and 5 outputs, so that plus one small scene is about the practical limit. 👉 Full step-by-step, code & wiring diagrams: https://accautomation.ca/run-two-3d-machines-at-once-multi-scene-plc-simulator/ 🔗 MORE RESOURCES ▶ Series: https://accautomation.ca/series/ ▶ PLC Beginners Guide: https://accautomation.ca/programming/plc-beginners-guide/ ▶ Free eBooks: https://accautomation.ca (subscribe for download) 🛒 RECOMMENDED HARDWARE ▶ Shop: https://www.automationdirect.com/ ▶ Parts Guide: https://www.accautomation.ca/purchase-find-parts/ 💬 Questions?
