 | 
| This Controller Parameters: | |
| 
 | 
 | 
| Communication | For the ENI configuration, this must be set to: | 
| Command | • 485CIF for MicroLogix and SLC | 
| 
 | • an unprotected write command for CompactLogix and | 
| 
 | |
| 
 | 
 | 
| Data Table Address | In this example we are using integer file 50, element 5 | 
| 
 | (instruction starts at N50:5). | 
| 
 | 
 | 
| Size in Elements | For all ENI TCP/IP data configuration, always set this to 4 (4 |

 | words). | 
| 
 |

 | 
| Target Device Parameters: | |
| 
 | 
 | 
| Message Timeout | Leave this value at the default. | 
| 
 | 
 | 
| Data Table Offset | Always 0. | 
| 
 | 
 | 
| Local Node Addr (dec). | This is the destination node address, in this example it is 101. | 
| 
 | 
 | 
| Local/Remote | Always Local. | 
| 
 | 
 | 
4.With the controller in Run, initiate the message. The new TCP/IP information is transmitted to the ENI.
