Solution
The Configurator
cannot
communicate with
the controller using
a direct connection.
The Ethernet crossover cable is not connected
securely to the controller and/or PC Ethernet
ports.
Check all connecti ons and replace the
cable if damaged.
A standard network cable is being used instead
of a crossover network cable.
Replace the network cable wi th a
crossover network cable.
The PC network adapter (Local Area
Connection adapter) is not configured properly.
The default network settings for the
controller direct connection are IP
Address 169.254.1.2 Subnet
255.255.0.0, and Gateway 169.254.14.
Your PC Ethernet adapter should be
configured with the values IP Address
169.254.1.***, Subnet 255.255.0.0, and
Gateway 169.254.14, where ***= any
number between 3 and 255. This can
be changed in Start/Network and Dialup
Connections/Local Area
Connection/Properties/Internet
Protocol/Properties (see manual).
The IP Address being used by the Configurator
is incorrect.
The default IP address for the controller
direct connection is 169.254.1.2. In the
Configurator's Connection Window,
click on Advanced and make sure this
is the IP address being used in the
connection attempt.
The proxy server settings are incorrect.
Open Internet Explorer. Go to
Tools/Internet Options and click on the
Connections tab. Click the LAN
