gama Posts: 15 Rating: (0)	Hi, i have to use two CP341 RS232c modules per one 315-2DP CPU. I have no hardware here and i must do the programming!!! any one can tell me, what should i do , to make sure that every thing is fine? Is there any chance of interferences between SEND and RECV IDB , also SEND and RCV WORK DB of the two modules? I have used FCs, FBs and DBs of Siemens' sample project ( zXX21-01-PtP-Com-CP34x// protokol RK512) for my project, but i have made some changes. will it be problematic?

Here are some article about the data transfer with RK512 protocol. Perhaps it helps you. 1. http://support.automation.siemens.com/WW/view/en/36748649 2. http://support.automation.siemens.com/WW/view/en/24416027 3. http://support.automation.siemens.com/WW/view/en/24414928 Good Luck Little Holmes
