From Schematic to Success: Mastering the Siemens LOGO! EPLAN P8 Macro

If you’ve ever built a control panel, you know the drill. You spend hours drawing the same basic 8/12/24V supply rails, painstakingly placing terminals, and wiring up that little smart relay. Then, you do it again on the next project. And the next.

If you are using EPLAN P8, there is a faster way to handle the ubiquitous Siemens LOGO! series: Macros.

Let’s talk about why using a pre-built EPLAN macro for the Siemens LOGO! isn’t just a nice-to-have—it’s a productivity game-changer. Siemens Logo Eplan P8 Macro

What is a Macro in the EPLAN Ecosystem?

For the uninitiated, a macro in EPLAN P8 is not a shortcut script. It is a pre-engineered, reusable graphical symbol that contains not just the visual footprint of a device, but its logical wiring, part number, connection point designations, and even technical parameters.

When we talk about a Siemens LOGO! Macro, we are referring to a digital "stamp" of the physical LOGO! module (e.g., LOGO! 8.3 12/24RCE or 230RCE). Dragging this macro onto an EPLAN page does more than drop a rectangle with pin labels. It imports: From Schematic to Success: Mastering the Siemens LOGO

  • All digital and analog I/O (I1 to I8, Q1 to Q4, plus expansion modules).
  • Integrated web server and Ethernet port configurations (for LOGO! 8).
  • Pre-assigned device tags consistent with Siemens nomenclature.
  • Part data for automatic BOM (Bill of Materials) generation.

Step 2: Draw the Symbol

Use EPLAN’s symbol library (IEC_symbols). For a LOGO!, you need:

  • A rectangular frame (using the Device frame tool)
  • Insert device: Select PLC/IO card or Generic component
  • Manually draw connection points (black boxes for inputs, circles for outputs)

Alternatively, download the Siemens LOGO! EPLAN macro from the official EPLAN Data Portal. All digital and analog I/O (I1 to I8,

You should build different macro types for different engineering views.

2. Use Macros for Typical Circuits

Don't just macro the LOGO! alone. Macro common assemblies:

  • LOGO! + 24V power supply + Isolator. Insert one macro for the entire power section.
  • LOGO! + DM8 + AM2. Create a vertical rack macro.
