E – Communication with SIMATIC S7
In this module, the reader is acquainted with the application options and use of web technologies in automation systems. The necessary steps for this are represented on the basis of a "CP343-1 IT" module. As an example, the visualization of a tank is used, in which the current process values can not only be displayed, but also modified. In addition, the specified tank applet is extended with further functions in order to obtain an insight into the development of user-defined applets.
The reader learns networked how two stations can be generated as CBA components, in order to be networked with IMap into an overall project. The two stations CPU 315F-2 PN/DP are used as PLCs. They are interconnected by means of PROFINET. Module E10 shows the method in principle, using a brief example.
