In several of the the previous lessons we have been discussing the many diagnostic tools available within the software environment. In a continuation of instruction about the Cross Reference tool, we are going to use a practical example to show you how to employ this useful troubleshooting tool. We begin by looking at an instruction in our network and notice that the logic is solving true yet we are not seeing the output as true in the simulator or the PLC outputs. We are then going to find out why that is the case. Let’s continue to learn about the valuable cross reference tool.
