PNIO - performance data

Even in the planning phase of a plant, it is important to know the reaction time of IO

communication and the delay time for data communication in a PROFIBUS,

PROFINET IO or Industrial Ethernet network. To provide you with reliable information

on typical plants with different topologies, a large number of different configurations

have been set up and measured. Based on these measured values, you can do the

following:

● Design plants ideally in terms of their communication response and

● Compare different plant configurations with each other

You will find the measured values by following the link below:
