As discussed in the previous course, discrete I/O (input/output) interfaces are the physical connection between the CPU and the physical field equipment. Analog modules translate continuous analog signals into discrete values. The rack enclosures contain the PLC (programmable logic controller) I/O modules. Each modules is identified by a unique address specifying its rack location.

The Inputs and Outputs training course builds on the understanding of I/O operations equipment and PLC program operation from the previous course. It describes the design and function of I/O interfaces. It also discusses the equipment used to produce and communicate I/O data. This online course includes:

• Discrete I/O
• Analog I/O
• Special I/O and serial communication interfaces
• Signal conditioning

Inputs and Outputs is part of the Programmable Logic Controllers training series.
