Hi, You seem to have a hardware interrupt enabled in your HW config, but your code do not have the associated HW interrupt OB. Further info about HW interrupt in What is a hardware interrupt and how do they work in the S7-400 system? You could consider two options: implementing code into OB40, or disable the hardware interrupt on the card. See the highlighted text below. Event 1 of 120: Event ID 16# 35A1 |

Hi, I did not get the chance to look at buffer anyways... EXTF means that An external error was detected, that is, the cause of error is not on the About OBs.. Have a look at the Which organization blocks do you need for error handling in STEP 7 V5.5? FAQ for overview. Make sure the fault OBs are downloaded to prevent further Stop events. I hope I could help! |
