Note 1: If Net DDE is enabled, the Alias Map entries will be registered as DDE shares for use by remote applications.
The names given to each Alias Map entry must not conflict with any existing DDE shares already defined on the server

How To... Use an Alias to Optimize a Project
In order to get the best performance out of a project, it is recommended that each device be placed on its own channel.
If a project needs to be optimized for communication after it has been created, it can be difficult to change the client
application to reference the new item names. By using an alias map, however, users can allow the client to make the
legacy request to the new Configuration. To start, follow the instructions below.
Unoptimized: Channel with multiple devices.
Optimized: Channel with each device under a different channel.
1. To start, create a new channel for each device. Place the device under the new channel and then delete the original
channel.
2. Next, create a New Alias for each device in the Alias Map. The Alias Name will be the original channel and device
name separated by a period. For example, 'Channel1.Device1.'
