Hello, the CPU 313C-2DP supports S7-communication via PROFIBUS but only as server. The consequence is, that "PUT/GET" is not possible, because these blocks are based on der Client-Server principle. The following compendium shows you in chapter 22.4.2, which constellations are possible http://support.automation.siemens.com/WW/view/en/20982954 Perhaps the S7-Basic-Communication is an alternative? Hope, it will help you. Pittiplatsch |

Hello s.p. das; With the integrated Profibus-DP ports on the CPU, you can only use master/slave exchanges. One of your CPUs must be configured as DP-master; the other as DP-slave. Here are a few examples of master/slave configurations using S7-300 and S7-400 CPUs, simply select the correct CPU 313Cto match your application when you follow the sample programs: DP link between CPU 315-2DP (slave) and S7-400 (master) with STEP 7 V5.3 What master/slave communication options are available on PROFIBUS DP?
1) DP master and DP slave are configured together in a STEP 7 project. Hope this helps, Daniel Chartier |
