Application Server architecture

Application Server relies on ArchestrA technology to provide services for distributed InTouch HMI applications. Application Server services are distributed across a set of nodes with the InTouch HMI installed on the Visualization Node to provide the application interface.

An Application Server Galaxy represents the system’s configuration based on a single logical namespace that incorporates a variety of components that are distributed across multiple nodes.

Application Server can store production data similar to InTouch tags, but it supports more data types and arrays. It can provide alarm capabilities that are compatible with the InTouch alarm system. Application Server provides an InTouch HMI compatible scripting language with significant enhancements for .NET function support. To be able to read and write Galaxy data, you need to install the Application Server Bootstrap component on the InTouch node. To be able to browse the Galaxy, you need to install the Application Server IDE component.
