The different IP address classes are defined in this table: The distribution of these bytes between the network address and the device address may vary.This distribution is defined by the address classes. O to the network to which the device is connectedĪn IP address is always coded using 4 bytes. Convert the MAC address to decimal format.Įxample: If the MAC address is 00.80.F4.01. NOTE: A MAC address is written in hexadecimal format and an IP address in decimal format. The default subnet mask is Default Class A Subnet Mask of 255.0.0.0. The MAC address of the port can be retrieved on the label placed on the front side of the controller. The last two fields in the default IP address are composed of the decimal equivalent of the last two hexadecimal bytes of the MAC address of the port.
NOTE: The two IP addresses must not be in the same IP network.
for Ethernet_2 (only available on TM251MESE) For example, with a MAC address of 00:80:F4:4E:02:5D, the IP address will be 10.12.2.93 X and y 5th and 6th bytes of interface MAC address. Speed and Duplex are in auto-negotiation mode. NOTE: If you change the Ethernet Protocol, a power cycle is required before it will be recognized by the controller.
Protocol type used (Ethernet 2 or IEEE 802.3) IP address, Subnet Mask, and Gateway Address are defined by the user. Used as device name to retrieve IP address through DHCP, maximum 15 characters.
