Dear all, I found this "Area length error when writing" message in the PLC diagnostics buffer. Attached is the diagnostic events and PLC hardware configuration. Please explain why this error triggered and how to clear this error. My PLC is running normally at the moment but I do not know the impact of this error. Thanks a lot.

Hi Piotr.M, Thanks for your answer. This PLC is configured as software redundant. Please see the PLC program attached. Could you please help recitify the instance DB with error? Thanks again for your help. Best regards, Eddie AttachmentPlant20161207.zip (100 Downloads) |

Hi I did compile and 1. in one of OB100 you have ---||--- twice for first scan. one should be ---|\|---! 2. it has updated some UDTs usage. did you change some UDTs in your program? 3. Compiled project attached - please compare with PLC to check which DBs are to be downloaded. I checked code in CPU-->BLOCKS. I did not touch code in separate project folders as they are not used in runtime. to compile project: Attached: Compiled project (you should have compile it yourself so a case of wine would be welcome ;-) ) //---compilation report
