Hello Bilal; You could look at the following diagnostic FB126, both for Profibus-DP and Profinet. It reads the error messages in OB86 and provides information on rack and station failures; plus, it gives you pre-programmed HMI screens that you can use to inform the operator of the status of your network. http://support.automation.siemens.com/WW/view/en/26996747 Hope this helps, Daniel Chartier |

Hello Bilal; Here is the information you requested: -No of the DP station: the Profibus address of the node -Logical base address: the Diagnostic address of the node, attributed by the Profibus configurator (in HWConfig editor) NOTE: this logical base address is often refered to a LADDR when used as a parameter in a library function (FC, FB, SFC, SFB). Your idea of using OB86 will work, with a little dediaction. You couls also look at this sample program for reading a DP slave's diagnostics from OB82 (Diagnostic OB): masybe you can study it for use in your program. http://support.automation.siemens.com/WW/view/en/2190197 Hope this helps, Daniel Chartier |
