Adding/Editing a Multihost Entry

When you click the Add or Edit button, the Host Entry window appears. The hosts in the multihost list must already be defined (see Host Table on page 88 to learn how to create a host). If you add a host that was defined with its fully qualified domain name (FQDN), it must be resolvable by your configured DNS server.

Configure the following parameters:

Host Name	Specify the preconfigured host that will be in the multihost list.
	Default: None
TCP Port	Specify the TCP port that the I/O channel or serial signal pin will use to
	communicate to the Host.
	Default: 0
