Open your largest completed S7-1200 project. Select the entire PLC schematic in EPLAN. Go to Page > Macro > Save . Name it Base_S7-1200_16DI_16DO . Test it on your next small project.
But what if you could generate your EPLAN schematic directly from your TIA Portal configuration? Or, at the very least, cut your design time by 70%? The answer lies in . macros eplan siemens s7-1200
When you build your macro, assign the symbolic names in the EPLAN macro properties. When you insert the macro into a new project, EPLAN will ask for a "Structural identifier" (e.g., =Conveyor1). Type it once. EPLAN automatically renames all tags inside the macro to "Conveyor1_Motor_1_Run". Open your largest completed S7-1200 project
This means your TIA Portal tag table and your EPLAN schematic are now mirror images without manual typing. Name it Base_S7-1200_16DI_16DO
It feels repetitive because it is repetitive.
If you’ve ever built a machine using a Siemens S7-1200, you know the drill. You map out the I/O in TIA Portal, then jump over to EPLAN to draw the schematic. You add the power supply, the PLC, the digital input card, and the relay outputs. Then you do it again for the next project. And the next.
