This manual describes the application interface of the Profibus-DP Slave Stack, with the aim to support and lead you during the integration process of the given stack into your own application.

Base of the development of the stack itself is the Hilscher’s Task Layer Reference Programming Model. It is a description of how to program a task in general, which is defined as a combination of appropriate functions belonging to the same type of protocol layer. It furthermore defines of how different tasks have to communicate with each other in order to exchange their layer information in between. The Reference Model is commonly used by all programmers at Hilscher and shall be used by you as well when writing your application task on top of the stack.
