3.1.1 Connecting the Hardware
The flow of ladder program development that is described in this chapter is based on the following system configura-
tion.
∗ In this chapter, M registers in the Machine Controller are used to simulate virtual I/O devices in the example system.
In practice, the input and output signals would be connected to I/O Modules on the Machine Controller, and the ladder program
would be created using I and O registers.
