8 Ethernet PLC-5 Programmable Controllers

Similarly, if you have a dynamic network configuration, DHCP or BOOTP

assigns the controller’s hostname. With a static configuration, you assign the

hostname.

When you create a hostname, consider these naming conventions.

• The hostname can be a text string up to 24 characters.

• The hostname can contain alpha (A to Z) numeric (0 to 9) and may

contain a period and minus sign.

• The first character must be an alpha character.

• The last character must not be a minus sign.

• You cannot use blank spaces or space characters.

• The hostname is not case-sensitive.

Auto Negotiate Speed Selection

In the Edit Channel 2 properties box, you can either leave the Auto Negotiate

box unchecked, which forces the port setting to a particular speed and duplex

port setting, or you may check the Auto Negotiate box, which lets the

controller negotiate a speed and duplex port setting.

If you check Auto Negotiate, the port setting lets you select the range of speed

and duplex settings that the controller negotiates. The default port setting with

Auto Negotiate checked is 10/100 Mbps Full Duplex/Half Duplex, which lets

the controller negotiate any of it’s four available settings. The following table

lists the order of negotiation for each setting.
