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. The first step is to determine if there is a spare point within the PLC, and if so, relocate the transmitter to a spare point. The second step is to change that points address within the PLC. Open up this lesson and we will guide you on how to take care of this problem.
In some previous lessons, we have discussed the many tools used within the TIA Portal programming environment. In this lesson, we are going to discuss the Cross Reference tool again but using the previous programming environment of Step 7. Cross-reference is a very useful function that works to f...
In this lesson, we continue discussing the Cross Reference tool in the programming environment of Step 7. We will open up the same project in both Step 7 and TIA Portal and compare the results of the Cross Reference tool search. We find that one environment is not only more advanced, in results, ...
In the continuation of our discussion regarding using some of the tools in the previous programming environment of Step 7, we are going to talk about the Assignment List tool. This lesson discusses some of the differences between the TIA Portal and Step 7 environments when using the Assignment Li...
