Server-based architecture

A server-based architecture distributes a common InTouch application to several View nodes. In the following figure, two View nodes access the same application from the development node.

For each View node:

• A logical drive must be mapped to the shared network drive of the development node.

• The shared application must be registered with the InTouch program.

• The computer must have identical access to any data sources referred to by the application. There are also ways to define the data source locations by using a combination of scripts to identify the node name and change each data location based on that name.

In this architecture, there is a single application to maintain. View nodes are automatically updated when the application changes and WindowViewer restarts.

Disadvantages of this architecture are:

• Development of application is restricted

• No redundancy if the development node goes down

• All nodes must have the same screen resolution
