The Siemens LOGO! series (LOGO! 8.3, LOGO! 7, etc.) is a compact, versatile logic module. However, manually drafting a LOGO! in EPLAN is tedious. A typical LOGO! 8.3 (12/24RCE) has 8 digital inputs, 4 relay outputs, an Ethernet port, and a power supply connection. Drawing this manually across multiple pages invites errors.
Using a dedicated macro delivers three core benefits: Siemens Logo Eplan P8 Macro
Nothing looks worse than a panel drawing where the LOGO! 8.3 is represented differently on page 5 than it was on page 2. A macro forces uniformity. Every engineer in your firm uses the exact same graphical layout and naming convention. The Siemens LOGO
The worst part of EPLAN is manually linking your schematic symbols to the PLC addresses (e.g., "I1" to "LOGO! Input 1"). When you build a macro correctly, the addressing schema is baked in. You drop the macro, and EPLAN already knows that the top left contact is address I1. 7, etc
When using macros for multiple LOGO! units in a single cabinet (e.g., a conveyor system with 5 separate LOGO! controllers):
EPLAN P8 typically handles Siemens LOGO! in two primary macro formats:
