Hello Abul Adnan, It looks like you got some alarms on your HMI Panel. Please have a look at the following link: SIMATIC HMI WinCC flexible 2008 Communication Part 1 See Appendix (9.1) for more information about System Alarms. Best regards, Wizard |

Hello Abul Adnan, I guess it worked for a long time? Could it be, someone did try to change a value. And the value that was entered was too high? So it is discarded by PLC. Best regards, Wizard |

Hello, So, these messages are coming back everytime? Since when does this happen? Did something change in plc or hmi? Best regards, Wizard |

Nothing has been changed except the re-commissioning of OP-277 with the old backup program which was done in January 2016 and since then it was running perfectly. These errors recurred during the previous week. Regards. |

Hello, Do you use any scripting in your project? Perhaps you can check in your project where the tag DB11DW22 is used. Best regards, Wizard |
