Simulation of a circuit program
3.3.1
Starting the simulation
Use the Tools → Simulation (Page 95) menu command or the simulation icon in the
programming toolbar to place your circuit program in simulation mode.
At the start of simulation, LOGO!Soft Comfort verifies the circuit program and shows any
At the start of simulation, LOGO!Soft Comfort verifies the circuit program and shows any
existing errors in the Info Window, which you can view by calling the View → Info Window
the function key [F2] in the Info Window to display the LOGO! modules capable of running
your program.
In simulation mode, you have the simulation toolbar and status window (Page 35) available
In simulation mode, you have the simulation toolbar and status window (Page 35) available
for performing the simulation and for observing and controlling the behavior of your circuit
program.
Note
You can simultaneously simulate only three of your circuit programs. A warning dialog
You can simultaneously simulate only three of your circuit programs. A warning dialog
reminds you when you try to simulate the fourth one.

Layout of inputs
LOGO!Soft Comfort displays inputs as key or switch icons, with the name below the icon. An
open input represents an inactive switch. When you click the icon, LOGO!Soft Comfort
switch it on and indicates that with red.

Layout of analog and frequency inputs
You can set the analog voltage or frequency values for analog and frequency inputs by
means of a slide resistor. Click the relevant block to display and operate this slider directly in
the diagram. If you want to specify a more precise value, enter it directly or set it directly via
the up/down keys beside the input window.
