When you start ModMultiSim the main dialog is displayed - this has display areas available for slaves and their registers and the environment.

At the bottom of the window is a status bar, which is used to display error and information messages.

To obtain a demonstration of a Modbus device simulation in operation, go to the File menu and choose a simulation from Simulation Examples... (see Running Example Simulations).

A quick guide to setting up ModMultiSim is given in the section Setting up ModMultiSim.

To exit from ModMultiSim, select the File → Exit menu item or type Ctrl-Q.
