2.7.2 Simulate runtime

Introduction

If you are not using an HMI device, you can simulate all used PLC tags with the

Runtime Simulator.

Note

Start the runtime simulation with the tag simulator

If you start the simulation without the tag simulator, the buttons and control elements will not

be active.

Runtime Simulator

Use the Runtime Simulator to simulate the process values of the connected PLC tags

independently of the program. Use the table of the Runtime Simulator to select the PLC tags

and to modify their values. The objects in the HMI screen react as though the tags were set

by the program of the PLC in runtime.

Procedure

To start the simulation of the HMI screen, follow these steps:

1. Start the runtime simulation via the menu bar. The HMI window must be active. If the

menu is inactive, first click on a free area within the HMI screen.
