Testing control

In the previous section, we learned how to override the inputs and simulate a signal on contact X001, which allowed us to trigger an output on the Y001 coil. We then proceeded to wire up the input side of the PLC to a switch and reproduce the same results, but this time with a physical input. Finally, we wired up our four-light Signal Tower. In this section, we are going to test the Signal Tower both from the DataView and from our SCADA VM by utilizing the MBtget tool that we installed in Chapter 2, Route the Hardware.

You will need to perform the following steps:

1. Open DataView1, as we did in the previous section; as a refresher, check the following screenshot, where you will find it in the Monitor | Data View section:

   Figure 3.44 – Data View

2. This will bring up the window for Data View. As we did previously, add the new contacts you created in the previous section. These contacts are X002, X003, and X004 in the address space. Make sure to enable...
