Part 3: The Workflow – From PLC4ME Ladder Logic to EPLAN Schematics

Let’s walk through a practical example. Assume you found a classic PLC4ME tutorial: "Start-Stop Station with a Latching Relay (Siemens S7-1200)."

The PLC4ME logic is simple:

• I0.0 – Start (Normally Open)
• I0.1 – Stop (Normally Closed)
• Q0.0 – Motor Contactor

Step 1: Create the PLC System in EPLAN

• Insert a PLC box (representing the Siemens S7-1200 CPU).
• Add digital input cards (e.g., 6ES7221-1BF32-0XB0).
• Add a digital output card.

Step 2: Define Addressing Exactly as PLC4ME Teaches

• In EPLAN’s PLC navigation pad, assign:
  • I0.0 → Physical terminal X1:2
  • I0.1 → Physical terminal X1:3
  • Q0.0 → Physical terminal X2:1
• Pro tip: Use EPLAN’s “PLC address” field – do not just type it as text. This enables the export of I/O lists for the PLC programmer.

Step 3: Draw the External Wiring (Per PLC4ME’s Sensor Diagrams) eplan electric p8 plc4me

• Connect a 24V DC push button to I0.0. Add a surge suppression diode (EPLAN’s part database will give you a manufacturer part number).
• Connect the emergency stop relay contact to I0.1.
• Connect the motor contactor coil (K1) to Q0.0.

Step 4: Generate the PLC I/O List

• EPLAN can export a CSV or Excel file. This is your contract between the electrical designer (you) and the software programmer (who might be reading PLC4ME at 2 AM).
• The list includes: Tag name, Address, Signal type, Cable label, and Terminal number.

Step 5: Handoff to the PLC Programmer

• The programmer opens the I/O list and creates the tags in TIA Portal or Studio 5000 exactly matching I0.0 = "Start_PB".
• They write the latching logic exactly as the PLC4ME tutorial shows.
• Result: Zero “pin mismatches” during commissioning.

Part 6: Building Your Own PLC4me-Style Macro Library

To truly master Eplan, you must build a macro library. Here is how to curate a library akin to the best PLC4me resources: Part 3: The Workflow – From PLC4ME Ladder

1. Create a Master Project: Build one project containing all your standard PLC racks (Siemens S7-1500, Allen-Bradley ControlLogix, etc.).
2. Define 20% Buffer: Always add 20% spare I/O points in your macro. Field modifications happen.
3. Save as Window Macro (.ema): Select the entire rack, right click > Save window macro. Save it to a shared network folder.
4. Add to Favorites: In Eplan, go to Utilities > Master data > Macros > Favorites and link the folder.

Now, every new project begins by dragging your "Standard 16DI/16DO Rack" from your favorites—saving hours of repetitive clicking.

2. Using EDZ Files for Siemens TIA Portal Integration

The holy grail of modern automation is Eplan <-> TIA Portal integration. TIA Portal integration.

• Eplan can export an AML (Automation Markup Language) file.
• TIA Portal imports it to automatically create the hardware configuration and PLC tags.
• Warning: This requires the "Eplan Pro Panel" and specific add-ins. Resources shared on PLC4me often show workarounds for standard licenses.
