Configuration
There are two methods of configuring a system:
z Configuring each device separately
Configure each device through the Global Data Configuration Web page (see
Global Data (Publish/Subscribe) Utility Configuration, p. 284). Repeat for each
device in the system. Entry errors may occur because the same information must
be reentered on each and every device, possibly as many as 64 times.
z Copying the configuration (preferred)
Configure all variable IDs, symbols (descriptions), and lengths on one NOE,
upload to your PC, download the same configuration to all devices and finish with
a small customization to each node.
When your planning is complete, follow the Configuring Your NOE steps below. We
present these steps both as a picture and as instructions.
Note: The Copy Configuration method reduces entry errors, allows for verifying
the configuration, and permits you to determine if the system is satisfactory for your
needs before implementing the configuration system wide.
You enter the variable ID, symbol (description), and length only once, thus
maintaining consistency.
