Dear all,
I am facing a problem ...system fault LED on in CPU314c-2DP .
I diagnosis the CPU and found error 'Illegal command in block(Detect by compiler)'
then I realize we tried PIW754 move to IW754 for forcing analog input and download.But it does not download. After that I deleted that move. In the mean time System fault glow. I compared offline and online there is no difference. Even I downloaded original FC block....no changed
System running...
Please help...
