Hello DCJeong; SFC13 will work, but you have to manage the cyclical call inside your program, and you have to call it once for each slave you need to monitor. if you are only looking at one drive, it shlould work fine. If you need to diagnose a complete bus system, get information on the module failures inside the slave as well as the sklave condition itself, and use standard visualization screens in WinCC, then you might want to look at FB126: http://support.automation.siemens.com/WW/view/en/26996747 I must say I have not worked directly with FB126, but I used its predecessor, FB125, in many Profibus projects, with great success. Hope this helps, Daniel Chartier |

Hi About SFC13 use F1 help for more details. I just follow this: Profibus address : 3 (for example) Just to clear my idea: Sample program: reading out diagnostics of a PROFIBUS DP slave in the OB 82. regards |
