Excuse me, If the SF/DIAG of S7-200 CN CPU 226 CN show red light, what should we do ? Thanks

Dear sir, The SF it mean that System Fault. So if you have backup file of program you can clear the PLC and then you try download program again.

But make sure you have the back up file of program otherwise the program will lost after you cleared.
