COMMUNICATION PROBLEMS

Hardware Problems —
communication issues caused by hardware problems.
Web Interface Problems —
tial communication issues caused by web interface issues.
SYMPTOMS
The unit does not respond to the
instructions sent by the supervi-
sion PC on the CCN bus.
Communication problem when
connecting two buses (primary bus
and secondary bus).
SYMPTOMS
Start-up page loads, then goes to
fault state.
While accessing the unit via the
web browser, the Java platform
launches, but remains blocked. No
file is loaded.
The application has been
launched, but the screens are not
shown in the web browser.
NOTES:
1. The unit cannot automatically obtain the network parameters
via a DHCP (Dynamic Host Configuration Protocol) server.
2. The intranet site address of the unit is the IP address.
See Table 20 for potential
See Table 21 for poten-
Table 20 — Hardware Problems
POSSIBLE CAUSES
Problem at the RS485 converter
level of the PC or connection prob-
lem on the primary CCN bus.
Electrical problem between 0 v
CCN of the primary bus and 0 v
CCN of the secondary bus.
Table 21 — Web Interface Problems
POSSIBLE CAUSES
Network property details are not
valid.
Ethernet network is not available.
Proxy server problem in the local
network.
A proxy server is used to access
the unit and this supplies the old
screens to the browser. Incorrect
configuration of the Java applica-
tion.
The intranet site of the unit is the IP address (see Unit IP
Address on page 49).
NOTE: The unit cannot automatically obtain the network
parameters via a DHCP server.
CHECKS
Check the CCN cable connec-
tions. The unit CCN address is 0.1
and the communication speed is
9600 baud by default.
Check the connection of the metal
part of the interface casing to
earth.
CHECKS
Check the network parameters
(see the section Ethernet/IP Con-
nection Problems on page 53).
Check to see if the orange LED on
the unit is flashing.
Contact your system administra-
tor.
Check that the web browser does
not go via a proxy server to access
the unit. Check that the Java appli-
cation does not store the internet
files on the PC.

SOLUTIONS
Replace the RS485 connector.
Connect the metal part of the inter-
face casing to earth.
SOLUTIONS
Contact your system administra-
tor.
Check the Ethernet connection to
the local network if the orange
LED does not flash.
In agreement with the system
administrator, open the Runtime
Java control panel and select
Direct Connection in the system
parameters and/or request in the
web browser (ToolsOptions
Connection System parameters)
that no proxy server is used to go
to the local addresses. If possible,
uncheck "use of an automatic con-
figuration script." Restart the web
browser.
Open the browser and in the sys-
tem connection parameters add
the IP address of the unit in the
proxy exceptions. (ToolsOptions
ConnectionSystem parame-
ters"No proxy for"). See the sec-
tion Java Application Configuration
on page 54.
