4.1
The IP Interface Secure in the network
The IP Interface Secure is designed for use in 10/100 BaseT networks compliant to IEEE 802.3.
The device features an autosensing function and sets the baud rate (10 or 100 Mbit) automatically.
4.1.1
Assignment of IP address
DHCP/AutoIP
The IP address of the device can be received from a DHCP server. This requires setting automatic IP
address assignment in ETS, see parameter window
setting, the device starts an AutoIP procedure and autonomously assigns itself an IP address from the
range 169.254.xxx.yyy.
The IP address that the device receives (via DHCP or AutoIP) during startup will be retained until
•
the next reboot (switching off/on or reprogramming).
a DHCP server is available
•
the DHCP lease expires
•
No DHCP server is available during startup
If no DHCP server is available during startup of the IP Interface Secure, the device will assign itself an
AutoIP address. The Interface then cyclically (three telegrams at intervals of 3 seconds, followed by a
pause of 20 seconds) searches for a DHCP server. As soon as a server is available again, the address
assigned by the DHCP server is used.
DHCP server fails (device has already received IP address from DHCP)
Each IP address assigned by a DHCP has a validity time for use (lease time). This validity time is
extended prior to expiry by means of a request from the device to the DHCP server. If the device's validity
time for use is not extended, the device searches for an AutoIP address after expiry of the validity time.
Static IP address
If the IP address of the IPS/S is to have a fixed assignment, a static IP address (as well as a subnet mask
and a default gateway) can be set in ETS, see parameter window
If no default gateway is available, the value must be set to 0.0.0.0.
4.1.2
Monitoring an IPS/S 3.5.1
If the device is to be monitored by a Visualisation that maintains a tunneling connection to the device,
the active tunneling connection should be used for monitoring.
If the device is to be monitored by a Monitoring Unit, monitoring should take place for the device address
and not for one of the tunneling connections.
