hi SD0011, for Master-Slave communication you need Profibus-Communication modules. One CPU need the Master-Module CM1243-5 6GK7243-5DX30-0XE0 The other one needs the Slave-module CM1242-5 6GK7242-5DX30-0XE0 the CPUs do also have a Profinet-interface which can be used for the communication between them. therefore one CPU needs to be projected as intellegent IO-device(I-device) for the other. the following application example shows how it works: Configuration and application of PROFINET I-Device function hope this helps, regards, |
