If you're interested in the field of industrial automation or looking to enhance your skills in the industry, PLC programming is a crucial skill to possess. Programmable Logic Controllers (PLCs) are widely used in manufacturing and process control systems, and understanding how to program them is essential for ensuring efficient and reliable operation.

In this comprehensive guide, we will explore the basics of PLC programming, covering key concepts and providing valuable insights for beginners in the field.

1. What is PLC Programming?

PLC programming involves creating a set of instructions that control the behavior of a programmable logic controller. PLCs are used to monitor inputs from various sensors, process that data, and execute specific actions based on pre-defined logic. By programming a PLC, you can automate complex industrial processes, making them more efficient and reliable.

2. Why Learn PLC Programming?

PLC programming offers numerous benefits in the industrial automation realm. By acquiring this skill, you can:

Improve productivity: PLCs enable automation, reducing manual labor and increasing overall productivity.

Enhance efficiency: Automation minimizes human error and optimizes processes, resulting in higher efficiency levels.

Facilitate troubleshooting: Understanding PLC programming allows you to diagnose and fix issues efficiently, minimizing downtime.

Expand career opportunities: PLC programming expertise is in high demand, with many industries seeking professionals with these skills.

3. PLC Programming Training Courses:

To learn PLC programming effectively, it's essential to enroll in specialized training courses. These courses provide a structured curriculum, hands-on exercises, and expert guidance. Here are a few key aspects to consider when choosing a PLC programming training institute or center:

Comprehensive curriculum: Look for a training program that covers both theoretical concepts and practical implementation.

Experienced instructors: Ensure that the training institute has qualified instructors with industry experience to guide you effectively.

Hands-on practice: Practical exercises and projects are crucial for gaining proficiency in PLC programming.

Industry relevance: Verify that the training course aligns with current industry standards and practices.

Certification: Opt for courses that offer certifications upon completion, as they enhance your credibility in the job market.

4. Key Concepts in PLC Programming:

Ladder Logic: Ladder Logic is the most commonly used programming language for PLCs. It employs graphical symbols to represent logic functions and control sequences, making it easy to understand and implement.

Inputs and Outputs: PLCs interact with the physical world through inputs (sensors) and outputs (actuators). Understanding how to read inputs and control outputs is fundamental in PLC programming.

Programming Instructions: PLCs execute a set of instructions to perform desired operations. These instructions can include timers, counters, mathematical operations, logic gates, and more.

Program Execution: PLC programs are executed in a cyclical manner. The PLC scans inputs, processes logic, updates outputs, and repeats the cycle continuously.

5. Programming Tools and Software:

PLC programming software provides an interface to create, edit, and debug programs. Familiarize yourself with popular software tools such as Siemens TIA Portal, Allen-Bradley RSLogix, or Schneider Electric Unity Pro, as they are widely used in the industry.

Updated | Judi Dench, the Academy Award–winning actor who has credited much of her Hollywood success to Harvey Weinstein, says she is horrified by the allegations of sexual harassment against the movie mogul and offers “my sympathy to those who have suffered.”

In a statement to Newsweek, Dench said: “Whilst there is no doubt that Harvey Weinstein has helped and championed my film career for the past 20 years, I was completely unaware of these offenses which are, of course, horrifying, and I offer my sympathy to those who have suffered, and wholehearted support to those who have spoken out.”

Dench, 82, has had a strong collaborative relationship with Weinstein since his former studio, Miramax, distributed the 1997 movie Mrs. Brown, Dench’s first starring role in a movie. Prior to that she was better known as a stage and television actor in her native Britain. Dench’s portrayal of Queen Victoria earned the star her first nomination for outstanding lead actress at the Oscars.

Dench earned her first Academy Award, for best supporting actress, for her role in Shakespeare in Love, another Miramax release. Their most recent collaborations include 2013’s Philomena and the delayed Tulip Fever.

In 2011, Dench joked that she had a tattoo dedicated to Weinstein on her buttocks to commemorate him making her a Hollywood star. “It was thanks to Harvey, whose name I have had tattooed on my bum ever since,” Dench quipped while accepting an award from the British Film Institute in London. In a 2014 interview with The Hollywood Reporter, the actor said the tattoo was an elaborate joke and was, in fact, applied with makeup.

Weinstein told the story of how Dench showed him a tattoo on her posterior, reading “JD loves HW,” in a 2013 interview on U.K. talk show The Graham Norton Show.

"She took me to the Four Seasons restaurant. She said: 'I've got a surprise. You're a guy who has everything. I don't know what to get you,’” Weinstein recalled.

Weinstein said that in front of fellow diners, including Carly Simon and the late directors Nora Ephron and Mike Nichols, Dench "unbuckles her pants, and on her bum was 'JD loves HW'...a tattoo. She said, 'I put your name on my ass.'”

Dench recounted her version of events to Hollywood Reporter in 2014, saying: "I once said to him: 'I have your named tattooed on my bum.' He laughed and was, well, quite embarrassed, actually. It’s quite difficult to embarrass Harvey, but I did.

"I got my makeup lady to actually write Harvey’s name. Then I brought it up at lunch and said: 'You know, I do have it on my bum,' and then I actually got up and showed him. I’ve never seen a man more embarrassed and I’ve never let him forget it. Perhaps I should have it done and really shock him."
