o Computer Automation in Manufacturing provide instruction in computer architecture, interfacing to mechanical systems, and software development for continuous control and discrete event systems. This is accomplished by presenting theoretical material and hands-on laboratory experiments.Rung 7: Enabling CR3 turns on the +Z motor control if CR1 is deenergized. ... 6.5 SEQUENTIAL CONTROL USING PLCs As described in section 6.3, a programmable logic controller can be used to replace the internal control logic of a relay control circuit. The example of Fig. ... Symbols have been simplified and they differ somewhat among PLC manufacturers; however, the differences are not very great.
