1.5.3 Lease-Time
The lease time determined and sent by the DHCP server
specifies the term of the assigned IP address. After half the lea-
se time has expired the W&T Web-IO Analog-In/Out attempts to
extend or update the address. If this is not possible before the
lease time expires, for example because the DHCP server can
no longer be reached, the W&T Web-IO Analog-In/Out deletes
the IP address and begins a cyclical search for alternate DHCP
servers for assigning a new IP address.
The lease time associated with the current IP address is no
longer available after a reset. After restarting, therefore, a
corresponding update request is made by the original DHCP
server. If the server cannot be reached at this time the W&T Web-
IO Analog-In/Out deletes the IP address and begins a cyclical
search for alternate DHCP servers.
If DHCP is enabled, the remaining lease time together with the
current IP address is displaced in seconds in the menu path

If the DHCP server is no longer accessible after expiration
of the lease time, the W&T Web-IO Analog-In/Out deletes its
IP address. All existing TCP/UDP connections between the W&T
Web-IO Analog-In/Out and other network clients are thereby
closed. To prevent such situations, we recommend configuring the
assigned lease time in the DHCP server to infinite whenever
possible.
