Chapter 7: Simulating Signals in the PLC
In this chapter, we'll look at different methods we can use to simulate devices and logic.
Siemens TIA Portal has a built-in simulation package that lets you simulate a variety of different CPUs and the logic within them.
In this chapter, we're going to cover the following topics:
- Running PLC/HMI in simulate mode
- Managing simulated inputs
- Creating a simulation interface
- Safeguarding outputs when in simulation mode
Running PLC/HMI in simulate mode
In TIA Portal, both PLCs and HMIs can be run in soft simulate mode. When this occurs, the hardware runtime is run from TIA Portal, instead of the hardware. This runtime then behaves in the same way it would as if it were running in the hardware.
