Chapter 3: I Love My Bits – Lab Setup

So far, we have been mostly configuring the connectivity of the network. Now, we'll take it to the next level. In this chapter, we are going to configure a simple program and use the software installed on the Windows 7 virtual machine (VM) to physically change the I/O on the PLC. This will pass through the VM interface, through the virtual switch, to the physical adapter. Then, it will pass to a physically managed switch and out to the PLC. This chapter will expand on the lab that we started to set up earlier in Chapter 2, Routing the Hardware. We will go through a demo approach using Koyo Click PLC and Human Machine Interfaces (HMI) I and connect it to physical I/O to learn how to turn lights on and off, utilizing both the graphical user interface and scripting.

In this chapter, we're going to cover the following main topics:

• Writing and downloading our first program
• Overriding and wiring the I/O
• Testing control...
