Using a DHCP Server To
Configure Your Processor A DHCP server 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.
ATTENTION: The processor must be assigned a fixed network
address. The IP address of the processor must not be dynamically
provided. Failure to observe this precaution may result in
unintended machine motion or loss of process control.
