KUNBUS-COM EtherCAT
84 / 135
0x400f Available Ports
In this memory register you will find out which port (physical link) is
connected to the EtherCAT network.
EtherCAT allows a connection speeds of up to 100MBit Full Duplex
for the data traffic.
– Connection speeds that meet this requirement have the value 1. These
ports can be used.
– Connection speeds that do not meet this requirement have the value 0.
These ports cannot be used.
Tip!:
You can find additional information in datasheet ET1100.

Station Alias (SA2-SA0)
– 000: memory register 0x4100 determines the
station alias
– 001: SSC determines station alias (reserved)
– 010: Fieldbus determines the station alias (default
value)
– 011: Settings on the rotary coding switches
determine the station alias. You can define the
format via bit 3
