There may come a time in your career that you are looking at your program and see that some transmitter that should be reading a value is currently showing nothing. After troubleshooting you may have determined that the channel that the transmitter is connected to is fried. When that occurs, whether it is an analog or discrete, input or output, you will need to take care of the problem with two steps.
