ENI/ENIW Configuration (Nodes 241 to 254) 4-23

2. Create your message logic using whatever conditional

instructions you may need. In this MicroLogix example, bit

B3:0/8 is used to condition the message instruction and message

file 10, element 1 is used to manage the message session.

3. Open the message instruction and enter the appropriate

variables. The variables are described in Table 4.9.

Parameters

Variable Setting

This Controller Parameters:

Communication

Command

For the ENI/ENIW configuration, this must be set to:

• 485CIF for MicroLogix and SLC

• a PLC2 Unprotected Write command for CompactLogix

and PLC-5

Data Table Address In this example we are using integer file 50, element 5

(instruction starts at N50:5) to set the ENI/ENIW’s IP address to

195.100.100.1.

Size in Elements For all ENI/ENIW TCP/IP data configuration, always set this to

4 (4 words).

Channel The RS-232 communication channel that is connected to the

ENI/ENIW, typically 0 or 1.
