The toolbar

A toolbar pops up when you open the simulation mode. It contains the following icons:

• Icons (for example, switches) for operator control of the inputs

• An icon for the simulation of a power failure , for testing the switching response with reference to retentivity characteristics after power failure

• Icons (for example, bulbs) for monitoring outputs

• Simulation control icons

• Time control icons

• Data Table icon

Arranging the toolbar

You can move this I/O toolbar to the left, right, top or bottom of the programming interface by drag and drop, same as the other toolbars. If your program is exceptionally large and contains many I/Os, you can also drag and drop the I/O icons out of LOGO!Soft Comfort individually to open them in a separate window. This ensures a clear layout for your simulation.

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).

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 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: The display of signal states and process variables is enabled under Tools → Options: Simulation.

The colored indication lets you identify the "1" or "0" status of a connecting line. The default color of connecting lines carrying a "1" signal is red. The default color of connecting lines carrying a "0" signal is 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.
