error in OB1

Hello Realmahmood;

The message is a warning (indicated as such by the yellow triangle), not an error. There is a big difference between the two. A warning is a signal that your programming procedure is not complete, and is suggesting how to correct that. An error message indiates a fault that cannot be directly or easily corrected by the programmer and requires immediate attention; often it leads to a CPU stop.

The message is telling you that if you do not downlaod the changes to OB1 (made by you since the last download) these will be lost. It suggests that you proceed to a download of OB1 before you close it. Nothing major.

Hope this helps,

Daniel Chartier
