In the previous lesson, we had a program that contained a comparator instruction and it properly executed our jump instruction. We then changed that instruction to a field input. When we forced that input to true in the simulator, we managed to put our program in an infinite loop, causing a Stop mode in the PLC. In this lesson, we will be working in the simulator again and viewing the diagnostics buffer. We will again make the program enter an infinite loop and while do so, we will check the diagnostics to see what is happening and what message we get with this error.
