• Less planning and assembly work than in the case of discrete components, thanks to the modular design
• Savings in hardware costs: Distributed I/O, 2 PROFINET connections and I/Os are combined in one device
• Keys and lamps can be labeled in IP65 using a standard printer (black and white or color)
• High flexibility due to freely configurable colors, switch/button function and integrated diagnostics function
• Any key color can be adapted dynamically to the process
• Integrated standard inputs and outputs for actuators and sensors, and each pin can be used as input or output
• Empty front designs can be used to reserve space for later system expansions and for easy mounting of standard 22.5 mm operator controls
• Functions and design are optimally matched in the SIMATIC HMI spectrum, e.g. in PRO device extension units
• SIL 2/3 safety with the "F" variants, e.g. emergency stop can be connected directly
