Use DHCP Software to
Configure Your Module
Dynamic Host Configuration Protocol (DHCP) software automatically assigns
IP addresses to client stations logging on to 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.
A DHCP server typically assigns a finite lease time to the offered IP address.
When 50% of the leased time has expired, the module attempts to renew its IP
address with the DHCP server. The module could be assigned another IP
address, which would cause communicating with the ControlLogix controller to
cease.
ATTENTION: To avoid unintentional control, the device must be assigned a
fixed IP address. The IP address of this device must not be dynamically
provided. If a DHCP server is used, it must be configured to assign a fixed IP
address for your device.
Failure to observe this precaution can result in unintended machine motion or
loss of process control.
