Where do you find information on transmission times on the PROFIBUS or Industrial Ethernet?

Part number:

Description:
The transmission time on the PROFIBUS and Industrial Ethernet depends on the cycle times of the implemented blocks (S7-300 or S7-400 CPU, PROFIBUS CP, Industrial Ethernet CP) and the volume of data to be transferred.

The following entry gives you a tool for determining transmission time for typical configurations on PROFIBUS 22180794.

The following entry gives you a tool for determining transmission time for typical configurations on the Industrial Ethernet: 22180793.
