• Continuous communication between sensors/actuators and the CPU
– Access to all process data, diagnostic data and device information
– Access to device-specific data, such as energy data
– Remote diagnostics can be performed
• Continuous diagnostic information down to sensor/actuator level
– Reduction in troubleshooting effort
– Minimizing risk of failure
– Preventive maintenance and optimization of service and maintenance planning
• Dynamic change of sensor/actuators parameters by the controller or the operator at the
HMI
– Reduction in downtimes during product change
– Increased variability of the machine
• Automatic reassignment of parameters when devices are replaced during operation
– Minimization of downtimes
– Device replacement by untrained personnel without additional aids
– Avoidance of incorrect settings
• Integrated device identification
– Identification of the installed devices
– Ensure quality of result in production and manufacturing when replacing the device
