Client-based architecture

In a client-based architecture, there is a unique copy of one InTouch application for each computer running WindowViewer (View node) or in a unique location on a network server. In the following example, an application is developed and tested on the development node and then copied to each View node.

There is inherent redundancy because each node can be self-sufficient, and there is no limit to the number of View nodes you can use.

Each View node must have an identical copy of the application and identical access to any network data sources, such as I/O Servers or the IndustrialSQL Server. However, each View node maintains a separate conversation with the shared server, which can result in increased network loading.

You can modify and test the application on the development node without affecting the running process. However, you must distribute the modified application to the View nodes. You must shut down each View node locally, copy the new application to it, and then restart.
