[Incorrect work plc online]

I could click on the button on the PLC screen. Changing the signal was displayed in the program. But the algorism itself was not fulfilled. I understand that some processes in the work are violated. I can not understand what's the matter.  

In addition to this, the error "CPU error detected"

[Incorrect work plc online]

Hi, all!

I stated to learn PLC UniStream. My program works correctly until recently. But today in online mode, the values of the coils did not change from the incoming signal. It was possible to manually replace the value, but then the algorithm was not executed. Although yesterday everything worked out normally
What is the problem? Help me please
