Fig. 41 Tcp/Ip Setting For The Ethernet Port - Beckhoff EL6751 Documentation

IP address of the port used
IP address/DHCP
In most cases an Ethernet port that is configured as an EtherCAT device will not transport general
IP packets. For this reason and in cases where an EL6601 or similar devices are used it is useful to
specify a fixed IP address for this port via the "Internet Protocol TCP/IP" driver setting and to disable
DHCP. In this way the delay associated with the DHCP client for the Ethernet port assigning itself a
default IP address in the absence of a DHCP server is avoided. A suitable address space is
192.168.x.x, for example.
