4-12ENI Configuration (Node 248 to 254)

Node 250 - TCP/IP Configuration

This procedure describes configuration for the TCP/IP parameters. The TCP/IP parameters are configured by sending a message instruction to the ENI (or by using the ENI Configuration Utility).

1.Configure a 485CIF write message in the Allen-Bradley controller.

	Only PLC2 type or 485CIF read/write messages
IMPORTANT
	can be used to configure the ENI.

2.Set the destination (target) node to 250. Using node address 250 directs this message to the TCP/IP configuration function.

3.The local integer file must be set up for at least 4 integer locations. The first 4 words define the IP address and are required. All remaining variables are optional.

The table below describes the TCP/IP functions that can be configured. The sections following the table describe the functions in more detail.

Table 4.3 TCP/IP Configuration Parameters

Function(1)	Data Type	Length	Notes
IP Address	Integer	4 words	Format aaa.bbb.ccc.ddd. The ENI verifies
			the first/highest octet of any IP as follows:
			• The first octet is between 1 and
			223 and not equal to 127 or 169
			• The first octet is 0, and the entire IP
			is 0.0.0.0
			• otherwise the IP address is treated
			as an error
			For example, 0.168.0.75 is an error, or
			127.0.0.0 is an error.
Subnet Mask	Integer	4 words	If not sent, the default mask is derived
			from the class of the IP address as shown
			in Table 4-13.
Gateway	Integer	4 words	Only needed if a Gateway is present on the
			Subnet. The default is 000.000.000.000.
Security Mask 1	Integer	4 words	If not present, the default is no security
			mask 000.000.000.000.
Security Mask 2

(1) The IP address must be configured. All other functions are optional.
