Input-Output Section

The I/O (Input/Output) section of the PLC is the part of the unit that all external devices are connected.

The I/O section communicates between the I/O sections and the CPU to carry out programmed functions.

A typical PLC has several I/O sections that allow for a variety of functions to be controlled.

We will distinguish between the input and output sections later in this module.
