How to Change the Transmission Rate and Operating Mode in the PC Network

Introduction
For communication in a network, ensure the following parameters are set consistently for all
network nodes:
● Transmission rate
● Operating mode
Note
The factory settings for Siemens devices are set so that parameters for the transmission
rate and operating mode are identified automatically (autonegotiation).
This setting only needs to be changed if nodes which do not have access to the
"Autonegotiation" setting must be communicated with in the network.
