Hi, The only waycommunication via Modbus for Siemens S7-series is Modbus RTU. The S7-300 can act as Modbus RTU slave or as Modbus RTU master, therefore you need an extra driver (which is also a plugin module) for the CP341. See for more information and downloads: http://support.automation.siemens.com/WW/view/en/18248289 http://support.automation.siemens.com/WW/view/en/22637279 |

It is not difficult, when you place the example in the CPU it will works. The only thing you have to search for are the FUNCTION CODES that are used from the RTU Kingfisher, those FC are programmed in the Hardware Projecting of STEP7 after you have installed the Modbus Slave driver and of course the serial cards programming. So you have to determine which FC are to programmed into the CP341. |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
