Hello, in thefollowingarticle you can find information aboutthe protocols which are supportes by the CPUsvia PROFIBUS. http://support.automation.siemens.com/WW/view/en/37950374 In you case I think S7 communication or FDL is possible. But youwill need minimum one CP342-5 because theS7-300 CPUsupports S7 communicationonly as server. In this casethe S7-300 CPU with CP342-5establishs activethe connectionto the other S7-300 CPUsand you use the function blocks FB14 "GET" and FB15 "PUT" to exchange data. When you use FDL you will needa CP342-5 for each S7-300 CPU and you use the function blocks FC5 "AG_SEND" and FC6 "AG_RECV" to exchange data. BestRegards Little Holmes |
