How to simulate PLC program without using real hardware
PLCSIM - help to simulate I/O, without using real hardware Step 1 . Download "Siemens.SIMATIC.S7-PLCSIM.v5.4.SP8.x86" from below link: Download PLC_SIM Step 2 . Install PLCSIM file (file download on Step 1) Step 3 . Make simple hardware/ program Step 4 . Download hardware: [1] open simulation -> [2] run PLC -> [3] download hardware Step 5 . Download software: [1] still open Simulation -> [2] stop PLC -> [3] download program Step 6 . Simulate: open input/output variable at "Insert" menu. Click on input 0.0, then output 0.0 and 0.1 will be ON as in program OB1 Note : if using "RUN-P" in simulation -> don't need to stop/start PLC to download software/hardware.
