In this example, the S7-215 DP is interfaced with the S7-315 DP by means of the Profibus. The S7-315 DP is the master, and the S7-215 DP is used exclusively as a slave device. To ensure faultless communication between the DP master and the CPU215 DP, certain settings have to be made on the participating devices.
The settings / initialization of the master with the program software STEP7 (starting with Version 3.1) will be explained in detail below. The sample program for the S7-200 demonstrates how you can apply the S7-300 inputs to the outputs of the S7-200. In addition, it makes it possible to represent the S7-200 inputs on the output module of the S7-300.
