Installing and Configuring the Module
16 840 USE 115 00 Version 1.0
Consult your network administrator to see if any of these conditions apply. If they
do, follow the directions on page 20 for changing the default configuration.
Note: If you will be changing the default configuration, you should stop the
controller, then install the module, then change the configuration before starting the
controller again.
The Ethernet web embedded server module only reads its configuration data at
power-up and when it is reset. Whenever the configuration data is changed, the
module must be reset, either by hot swapping or through a reset command in the
MSTR block (see page 37). Once the module is installed, stopping and restarting
the controller will not reset it.
2.1.2 Verifying that the Network Has Been Constructed Properly
You should not connect an Ethernet web embedded server module directly to
another device with a length of cable. For the network to operate properly, you
must route the cable for each device through an Ethernet hub. Hubs are widely
available and can be purchased from many suppliers.
