BhaPraJ Posts: 519 Rating: (83)	[quote user="KIRAN_DABHI"]MESSAGE IS REMOVED BUT LED STILL SHOWING INTF ON PLC. Both are different issue, there is no connection between INTF LED & Project Structure Error. As Project structure error is solved. So for INTF LED, check diagnostic Buffer. . You may find the absolute reason for INTF LED. Most probably "Area Length Error" or calling of FC or FB whuch are not available in Online Program of CPU. .

Hassan Raza Posts: 102 Rating: (2)	Hi Kiran, Well internal fault LED is normally lit up due to error in coding or usage of undefined DB address. Please follow this PLC>diagnostic/setting>hardware diagnostics and check which function is causing the fault. Please remember you can only open hardware diagnostics when cpu is in running condition. Also the error would be like " Area length error".
