Simulation toolbar and status window

The toolbar

When you open simulation mode, LOGO!Soft Comfort displays the simulation toolbar, which contains the following icons.

Click "<<" to hide a partial area of the toolbar. To show this area again, click ">>".

Simulation control icons

Start simulation

Stop simulation

Hold simulation (pause)

Simulate network. If no IP address is configured for a circuit program in LOGO!Soft Comfort, the network simulation icon is inactive (grey-colored).

Show message window

Time control icons

If you have programmed a time-sensitive circuit, you can use the time control to monitor the reaction of your circuit program.

Start simulation for a specific time or number of cycles.

Set the period and the number of cycles using the following icons.

Set the period and the time base for a time-limited simulation or set a specific number of cycles

Display the current time in LOGO!Soft Comfort

Modify the current time in LOGO!Soft Comfort

Data Table icon

You can view VM (Variable Memory) values in a data table. For simulation, the values are updated each cycle. For online test, the values are updated after each communication.

Status display

Prerequisite: You can enable the display of signal states and process variables with the Tools → Options: Simulation command.

The colored indication identifies the "1" or "0" status of a connecting line. By default, connection lines carrying a "1" signal are red while the lines carrying a "0" signal are blue.

Example for the FBD Editor:

PI controller trend view

If your circuit program includes one or more PI controller function blocks, the simulation displays a trend view window of the analog output that shows the change in the AQ and PV values relative to the SP parameter over time. The trend view is continually updated while the simulation is in progress, at the frequency of the sample period that you configure. You can enable or disable the individual displays of the AQ, PV, and SP trend graphs as you choose.

If your circuit program has more than one PI controller function block, the trend view has a separate tab for each PI controller.
