BootP server

The following example describes IP address assignment using a BootP server in
PC Worx Express for the ILC 151 ETH.
In an Ethernet network, BootP is used to assign an IP address to a BootP client using a
BootP server. For this example (delivery state of the ILC 151 ETH), the ILC 151 ETH (BootP
client) sends a Boot_Request as a broadcast in the network. The MAC address of the trans-
mitter is sent with the Boot_Request to provide unique identification. If the BootP server has
been activated in PC Worx Express, PC Worx Express responds with a Boot_Reply.
PC Worx Express uses this Boot_Reply to inform the ILC 151 ETH of its IP address and
subnet mask. Please ensure that:
– The BootP server knows the MAC address sent by the BootP client.
– A corresponding IP address and subnet mask have been assigned in PC Worx Express
for the MAC address.
Once the IP data has been transferred to the ILC 151 ETH successfully, PC Worx Express
sends a corresponding acknowledgment message.
