X20IF1061-1 Data Refresh Speed

The customer added some sensors to the project for algorithmic calculations. The communication is PROFIBUS DP. The project originally used X20IF1061-1. The customer asked if the communication speed has been tested: how many milliseconds does it take for the variable to be refreshed?different baud rates, different communication bytes, different number of slaves, different data exchange time

Hello,

that’s not so easy to answer. It depends on where the interface card is plugged in. If it is plugged directly into an X20CPU, then it depends on the set baud rate of the Profibus interface and the set data exchange time of the interface card and the clock time of the CPU. If the interface card is plugged into an expandable bus coupler, then the Powerlink cycle time also plays a role.
