This function obtains the status of the CPU LED indicators, for visualization on an HMI, for example. In this function block, we only output the status for system fault and a combined bus fault (for any interface), but you can easily change that.
When writing a function / function block, you need to determine what parameter types you will expect. Sometimes, it would be nice to be able to determine that depending on the application.
For example, in the post Step 7: analog signal normalization the output parameter could be a pseudo percentage of type INT or a motor current of type REAL.

I have just canceled my Pro subscription. It was scheduled to renew in two days from now. I also deleted almost all of my thousands of photos from the service, most of which were set to friends and/or family.
