Industrial automation technologies have made manufacturing processes increasingly more efficient. Programmable logic controllers (PLCs) are commonly used in industrial automation, and many of these ...

When a PLC is used primarily to replace relays, timers, and counters, it's hard to beat the simplicity and usefulness of ladder diagram programming. Their ability to accept programming in ladder ...

In part one of this series, we looked at the PLC’s internal architecture, briefly discussed Ladder Logic programming, Human-Machine Interfaces, advantages of the PLC’s ability to react consistently ...

If you are used to conventional programming, you may find ladder logic a little frustrating. Originally, it was a documentation tool for relay logic but has grown to handle modern cases.

The debate between programming languages revolves around the necessity of sticking to ladder logic for ease of troubleshooting versus adopting higher-level languages for enhanced functionality and ...

Basics of Ladder Logic provides an overview of the basic principles, structure, and symbols of ladder logic programming. This class introduces the components of ladder logic programming language used ...

The interesting challenge early on in its development was to design a programming language that would allow the industrial electrician a familiar way to communicate with the electronics of the PLC.

THE use of function blocks for programming of programmable logic controllers (PLCs) is gaining wider acceptance. Rather than the classic “contact and coil” representation of ladder diagram or relay ...

THE HUMAN-MACHINE INTERFACE Among the ways to interface and program the PLC, you may use a PC running the programming software and “hard-code” the program parameters such as set points, timer delays, ...

As the title suggests, I'm looking for something to help me learn the basics of PLC programming. We're looking to develop the ability to do it in-house rather than wait for a contractor to come in ...
