XPress™ DR Industrial Device Server User Guide 71
Problem/Message Reason Solution
The device server appears to be
set up correctly, but you are not
communicating with your device
attached to the device server
across the network.
If you are sure that the serial port
setting is correct, then you may
not be connecting to the correct
socket of the device server.
Check the cables and wiring.
You can check to see whether
there is a socket connection to or
from the device server by looking
at the Ready LED.
If the Ready LED is blinking
consistently then there is a good
socket connection.
If the Ready LED is solid green,
then the socket connection does
not exist. Use the Connect Mode
option C0 for making a connection
to the device server from the
network. Use Connect Mode
option C1 or C5 for a connection
to the network from the device
server. See the full list of Connect
Mode Options in the Binary to
Hexadecimal chapter.
When connecting to the Web-
Manager within the device server,
the message “No Connection With
CoBox” displays.
Your computer is not able to
connect to port 30718 (77FEh) on
the device server.
Make sure that port 30718
(77FEh) is not blocked with any
router that you are using on the
network. Also make sure that port
77FEh is not disabled within the
Security settings of the device
server.
