Bus fault problem in 417 5H PN DP

Hello Chintan;

Your BFx LED is active? I suggest you open the diagnostic buffer of the CPU and see what messages are logged there that are linked to your problem. The diagnostic buffer is a tool used by the OS of your CPU to register every error or status message generated during CPU activity, so it can be of great help when you need to locate the source of an error.

Sometimes the messages can be hard to decipher, specially for a new user. So you could save the contents of the buffer (there is a SAVE AS.. button), that will send all messages to a exyt file that you can attach here for help.

Hope this helps,

Daniel Chartier
