Hello prabhu; Our friend Satchinpatke has given a few good suggestions that can apply to your project in the following thread: https://support.industry.siemens.com/tf//ww/en/posts/diagnostic-program/102763/?page=0&pageSize=10 You can get much of the information you are looking for using SFC 51, Read data record, and the correct SSL ID# identifying the module you want to read from, and the Index for the specific data you need to import. The SSL list and description is available from the System and Standard Functions manual, Chapter 34. Read up on the use of SFC 51 in the same document. https://support.industry.siemens.com/cs/ww/en/view/109751826 The screenshot below shows for example the type of data you can collect from a S7-400H CPU, with SFC 51, SSL-ID w#16#0174, and Index w#16#0001 to w#16#0080 (LED status of the redundant CPUs).. Note that w#16#.... indiactes this is a hexadecimal notation in your program. Hope this helps, Daniel Chartier |

Hello prabhu; Siemens offers Application Examples that contain examples of the use of various functions, such as SFC 51, in a realistic environment. You should look at the documentation and code for this application, to have an idea of how to use SFC 51 in your own project: Realization of a Fault-Tolerant Tunnel Lighting System With S7-400H https://support.industry.siemens.com/cs/ww/en/view/81066268 Hope this helps, Daniel Chartier |
