Hi, Probably the reason of the behavior is the improper setup of the CPU. The Local data is not enough for the priority class.OB88 manage to get your processor going but the error still there. In some processor you can change the local data size. See Step7 programming manual(ID: A5E02789666-01) under chapter "27.2.3.3 Local Data Stack" for overall description. Along other things it is written there: "Assigning Local Data to Priority Classes If you need further help, please upload your diag buffer, and information like you CPU type etc... |

Check this program, When error occured i programmed to prevent the error by using OBb88 but my question is how to reset the SF led on the plc using programming. i.e, for example if any bus fault is their plc will show BF fault led when it is rectified BF led automatically went off, the same functionality i require for SF fault led.

Do not call FC1 in FC2! Then there is no system fault! |
