Configure the Module for Your EtherNet/IP Network 25
allows for dynamic allocation of network addresses and configurations to
newly attached devices.
Be aware that a DHCP server typically assigns a finite lease time to the offered
IP address. When 50 percent of the leased time has expired, the module will
attempt to renew its IP address with the DHCP server. The module could be
assigned a different IP address, which would cause communicating with the
ControlLogix controller to cease.
Chapter Summary and
What’s Next In this chapter, you learned how to configure the module to communicate on
your EtherNet/IP network by providing an IP address, gateway address, and
Subnet mask. The next chapter describes an example application in which you
configure discrete I/O.
ATTENTION
To avoid unintentional control, the module must be assigned
a fixed IP address. The IP address of this module should not
be dynamically provided. If a DHCP server is used, it must be
configured to assign a fixed IP address for your module.
Failure to observe this precaution may result in unintended
machine motion or loss of process control.
