The CPU provides dedicated HMI connections to support up to 3 HMI devices. (You can have up to 2 SIMATIC Comfort
panels.) The total number of HMI is affected by the types of HMI panels in your configuration. For example, you could
have up to three SIMATIC Basic panels connected to your CPU, or you could have up to two SIMATIC Comfort panels
with one additional Basic panel.
