This module covers all aspects of the Input/Output system for PLCs including discrete, analog, and data I/O. In addition, the module also presents an overview of I/O addressing and an introduction to Allen-Bradley I/O parameters. Module topics also include the principles of remote I/O and an introduction to scaling and resolution of analog devices and signals.
