BootP Server
Overview ProWORX 32 supports the configuration of the IP Address of a Quantum NOE
Ethernet adapter, an ENT module or a Momentum controller via an Ethernet
network. The BootP server lets you record and configure a device’s IP Address and,
optionally, the Gateway IP Address and Sub network mask.
Using the BootP
Server
In the navigation panel, utilities tab:
BootP Listening When a BOOTP client such as a PLC requires an IP address, it broadcasts a request
for an address across its Ethernet connection and through the TCP/IP network. It
continues broadcasting these requests periodically until a reply is received or a set
amount of time has passed. In the case where a PLC has a TCP/IP configuration
extension active, the information in the extension may be used to configure an IP
address if a BootP response is not received. The BOOTP Server listens for these
IP address requests and responds accordingly. The response includes an IP
address for the client. When the response is received, the client uses this new IP
as its own and may then be accessed normally through the TCP/IP network.
Using BootP
Listening
In the BootP Server utility:
Step Action
1 Select Boot P to open the BootP Server utility.
2 To enable active pinging of devices in the list, select the Enable Active Device
Ping check box.
3 To check if there is a device at the specified IP address, click Ping. If successful,
the status field displays ‘Device found at specified IP Address’.
4 To exit the BootP Server utility, click Close.
Step Action
1 Click Start Listening to make the BOOTP Server listen for incoming IP
requests. The BOOTP Server now responds to any BOOTP IP address requests
coming from Modicon devices.
2 Click Stop Listening and the BOOTP server ignores any incoming requests.
