Transferring the process data to DP slave S120
The process data of the machine axes are read by the DP master from the configured I/O
addresses and transferred to the DP slave S120 in the PROFIBUS message frame
according to the configured object sequence.
Reading the process data from DP slave S120
The process data of the machine axes are read by the DP master in the configured object
sequence from the PROFIBUS message frame and transferred to the corresponding I/O
addresses.
