System information

If a configuration script is used, it is not possible to add the
unit IP address to the exceptions list. In this case, see the sec-
tion Java Application Configuration below.
If the response to the “ping” command is negative, verify
the IP address of the PC and the IP address of the unit. They
must have the system network and sub-system in common.
The last part of the IP address is the host number and must be
unique on the sub-system; for example: Unit address —
172.30.101.11 and PC address — 172.30.101.182. In this
example, 172.30 corresponds to the system network, and
101 corresponds to the sub-system. The host numbers are 11
and 182 respectively.
ETHERNET CONNECTION ON THE PC — Open the
network configuration window of the PC and double-click
Network Connections. Find the system interface board and
check that no red “X” appears on the icon.
The connection to the local network must be authorized and
in the connected status. If this is not the case, check the connec-
tions and authorize/repair the network connection.
JAVA APPLICATION CONFIGURATION — Open the In-
ternet configuration window of the PC and double-click the
Java application icon. If Java is not installed, a free download is
available at http://www.java.com.
If Java has already been installed, check if it is used by other
applications. If so, check that these are compatible with the fol-
lowing settings in the Java control panel. See Fig. 66.
