Sub-Network - Walchem WebMaster ONE Instruction Manual

Note: Control is suspended during a software upgrade. If the controller being updated is a slave on
a network of WebMasterONEs, both the master controller and the slave being updated will have
control suspended during the upgrade process. Depending upon the extent of the changes and
Internet traffic, the upgrade can take anywhere from 15 minutes to 2 hours to complete.

Sub-Network

Once you have created a network of two or more WebMasterONE controllers using Ethernet cards
(see Figure 7 for wiring), purchased the Master Capability software for the master controller,
defined the master unit as the master and slave units as slaves (see section 6.46) in the
Communications page, and given each controller unique Ethernet IP addresses in the
Communications page, then the links under Sub-Network will be active.
To navigate between controllers on the sub-network, start by logging onto the master controller.
This may be via USB, Ethernet or modem. Once connected to the master, click on a link to the
slave. The link will be given the custom name of the controller from the Startup page. The first
time you connect to the slave in a given session, you will need to log on with that controller's user
name and password. After that, you will be able to bounce from one controller to another without
logging on again.
If the links available do not accurately match the controllers on the network, go to the
Communications page and click the 'Detect Network ' button. If the sub-network frame is still
inaccurate, right click in the frame and click 'Refresh.' If still inaccurate, try rebooting the
controller.
