DearTagolover Yes this address has been shown in "OB121_PRG_ADDR" interface of "OB121", and this address refers to instruction whitch has generated the fault, but i mean what is the relation between this number and actual position of the nstruction whitch has generated this error? Best regards Ali. |

Hello , It is better to consult STEP7 online manual (See the attachment). OB121_PRG_ADDR : WORD --> Relative address of the MC7 command that caused the error (no valid value is entered here for an S7-300) LAD/STL/FBD editor converts your logic to MC7 codes. As far as I know,MC7 is known for the editor and this guide you to point of error in case of error. Best regards Hamid Hosseini AttachmentOB121.pdf (1014 Downloads) |
