Hi to everyone, I have a problem: Area length error when writing Global DB, word access, Access adress: 286 FC number:82 Module adress:76 Requested OB: Programming error OB (OB121) Priority class: 1 Internal error, Incoming event What does this mean? That some DBx.DBW286 does not have enough length memory? And that this varuable is in FC 82? Why is this module adress 76 mentioned? Thanks a lot Splitted from Area length error when writing, OB121. |

Hello drozerce, This error is caused when trying to write in an area notdefinedin a DBX. In your case somewhere in the FC82 you arewriting in DBX.DBW286 variable (T DBX.DBW286) that is not defined in DBX. At the "Help onevent" button you can find the following informations: Causes: -The value addressed using the access address is outside or not completely within the permitted address range (the range varies depending on the particular CPU). -Due to a faulty address calculation, the value addressed is > 65535. For indirect addressing, an address value greater than 65535 can occur due to faulty calculation. This value cannot be correctly entered in the detailed information for the event. In this case, a 0 will be entered and displayed as the access address for S7-300, and for the S7-400, the calculated value modulo 65535 will be displayed and entered as the access address. To correct or avoid errors: -Select the access address so that the addressed value is completely within the permitted address range. -Check your user program. |
