Automatic identification of the transmission rate and operating mode
Make sure there are no inconsistencies in Ethernet CPs, switches and network adapters in
terms of their settings/properties for data transmission rate and bus access procedure.
We recommend using the default Autonegotiation setting (procedure for the automatic
negotiation of the best transmission mode between two network interfaces which are directly
connected to one another).
The term autonegotiation denotes the automatic identification and negotiation of transmission
rate and operating mode (full duplex/half duplex).
● Full duplex is an operating mode with bidirectional data communication, where the
communication partners can send data on the transmission link independently of one
another.
● Half duplex is an operating mode with bidirectional data exchange, in which only one
communication partner at a time can send data on the transmission link.
Requirement
The "Autonegotiation" setting needs to be changed if nodes which do not have access to this
setting must be communicated with in the network.
