Due to the large variety of communication processors protocols and user interfaces in the SIMATIC homogenous system world . only SIMATIC systems communicate with each other and particularly in the heterogeneous system world . SIMATIC systems communicate with third party automation systems this topic is extremely complex. Basic knowledge of the principles behind protocol mechanisms protocols utilizable with the bus systems as well as their properties are just as important as the concrete implementation of a solution approach on the basis of proven application samples. Specific problems with the communication tasks From the user s or planner s viewpoint the following questions may often arise when planning the communication solutions 1. Which Bus System is available as platform for the planned automation solutions 2. Which Protocol can be efficiently employed for the planned task on this bus system and will be supported by the systems to be connected 3. How will these Protocols be used to achieve effectively the desired automation solution 4. Which further mechanisms are required to solve the given task effi- ciently Objective of this document The reader is enabled to face the concrete problems within the planning and configuration phase in two steps 1. The main document which prepares and clearly displays the basic information about possible bus systems and protocols being essential for the user. 2. A collection of the applications which are complete within themselves which takes up typical communication problems and offers .
