4-12 Configuring the 1756-ENBT Module
Using DHCP Software to
Configure Your Module
DHCP (Dynamic Host Configuration Protocol) software automatically
assigns IP addresses to client stations logging onto a TCP/IP network.
DHCP is based on BootP and maintains some backward compatibility.
The main difference is that BootP was designed for manual
configuration, while DHCP allows for dynamic allocation of network
addresses and configurations to newly attached devices.
Be cautious about using DHCP software to configure your module. A
BootP client, such as the 1756-ENBT module, can boot from a DHCP
server only if the DHCP server is specifically written to also handle
BootP queries. This is specific to the DHCP software package you use.
Check with your system administrator to see if your DHCP package
supports BootP commands and manual IP allocation.

The following chapter describes an example application in which you
configure remote digital I/O using a rack optimized connection.
ATTENTION
!
The 1756-ENBT module must be assigned a fixed
network address. The IP address of this module must
not be dynamically provided.
Failure to observe this precaution may result in
unintended machine motion or loss of process
control.
