PLC Training

12/27/2008 2:18 AM

I wish study PLC programming. Is there any one who can advice on how to go about this or who knows any firm providing this kind of training a as home training course??

To hear from you.

Regards

Aje Thomas

I bought LogixPro A/B SLC 500 simulator here on line for $20.

It is a good resource.

It is Same as On line PLC course for $1000+ US and you still have to register with the Logix web site aka The Learning Pit .com , Hidden in the learning pit web site is a Siemens S7 training course that is also excellent.

The textbook for the Logix Pro course is Programmable Logic Controllers by Frank D Petruzella it runs about $150 Can. The Learning Pit .com was developed in a college in Ontario Canada.

There are several very good sites that are dedicated to PLC topics. One of the best is this one: http://www.plcs.net/

Register with the site and dig around. There is very good basic beginner to advanced information available and some good links. Our open forum has some of the very brightest programmers there that are involved with a wide variety of PLCs.

I've never messed around with some of the available simulators but I've heard there are some good ones that help learning.

Also...something very important to understand and focus on... a PLC is just another machine control device. In order to apply it properly and safely you must have a very solid understanding of general control methods. I've been dealing with PLCs for a long time and have seen some seriously stupid things...dangerous things. So please take the time required and truly study and apply safe control methods.

Good luck.

There is some information that has been posted on other threads that may be of help to you.

http://cr4.globalspec.com/thread/22370/Books-About-Ladder-Logic

You also might try doing a site search, I'm sure there is a wealth of information on the type of training you are seeking.

Hello!

I am a teacher, student and business dedicated to the art of the PLC! Please tell me for what purpose you would like to use your PLC control system and I may be able to get you started. The curriculum would follow this path:

1. Hardware: Controllers, devices, wiring, communication

2. Ladder Logic: Sequences, simple and complex logic

3. Commissioning and Validation

4. Maintenance and Troubleshooting

Let me know your intentions?

Please review my website for further details: www.innovativelogicalcontrols.com

For the last number of years,I ve been looking into the possibility of learning another skill.I first learned of plcs was when I worked for a contractor in a automotive plant in ontario. I was sold on the technology I read a number of articles on automation,which included robotics and programmable logic controls at the present time I am involved with learning about computers and their relationship with the programming of a plc. Could you list for me the proper priorities or methods of learning this field successfully. THANK YOU mike baldry

Mike- Are you the Mike Baldry that I sent the info package to from Innovative Logical Controls?

Here is my curriculum. I hope to begin teaching it at adult oriented vocational schools in NJ beginning in September 2009.

Curriculum:

Programmable Logic Controls – History & Application
PLC Functionality – The inner workings of the PLC
Peripheral Devices – What the PLC will control through device monitoring and actuation
System Design – Designing a simple system for the classroom lab
Ladder Logic – The written instructions that drive the PLC
PLC Panel Construction – Putting it all together safely and conforming to the code (classroom lab & lecture)
PLC Programming – Powering up the panel, sequences of operation, loading the project ladder logic (classroom lab & lecture)
PLC System Start-Up and Commissioning – Device Check-Out and Operation
PLC & System Troubleshooting – Creating errors & faults and subsequent repair

Dear jcchiefeng

I am a NJ resident.

I would appreciate it if you would post when and where your training sessions are being held.

Yes, I will send you the update. Look for an announcement in August 2009 on my web site, www.innovativelogicalcontrols.com

Re: PLC Training

Friend,

As Switchman has said, there are many dangerous and stupid things which can be done with PLC's. Let me suggest just a very few overall guidelines:

1. Do not use the PLC for emergency stop or safety circuits, unless it has been specifically designed and tested for this type of use and you are a very skilled programmer.

2. As with all other computer systems, "garbage in, garbage out". Spend a lot of time at the beginning of a project with defining exactly what the project is supposed to do, and describing in exhaustive detail what each control point or device will do, along with when and why.

3. Document your program extensively. When you have problems, and if you come back to it even a week later, this will help you immensely.

4. A fundamental difference between PLC and hard-wired control is that the PLC logic is solved in sequential order while wiring is fully parallel. This means that the order of "rungs" or instructions can be VERY important in a PLC program while it is innocent in a wired control panel.

5. Timing can be everything. Processor speeds are different from one to another, and program execution times can be very different. Many processes in the real world can be quite sensitive to timing problems. Certain instructions can take a surprisingly large amount of time to execute, particularly those involving communication.

6. As you distribute the intelligence and control to PLC's and embedded controllers, you increase the number of places to look for the solution to a problem. This can lead to "premature baldness" as you "pull your hair out" while trying to find the problem and then solve it.

7. Wired controls have problems with the number of contacts you can put on a relay and with keeping track of changes which have occurred since the equipment was first installed. PLC controls have a problem with failure to document them and obsolescence of equipment or failure to keep a backup of the program.

8. Just because you can do something does not mean it is going to be helpful to the users or even be used. Just because you have a PLC and can program it doesn't mean that every problem is a PLC type of problem.

9. Human factors. You can automate something or solve a control problem with a PLC, but if it doesn't act the way people expect or appears to be doing nothing, try to provide enough cues to the workers and operators so they don't see the PLC as an enemy and are encouraged to work with it in the way it is programmed instead of bypassing it or worse.

You will make mistakes, but be safe and learn.

--JMM

The above link is to a free online book that covers some general PLC topics and gets specific with Omron's CPM1A PLC and SYSWIN programming software. You can PM me for more details if you want.

At Automation Direct's website you can download many of thier software's on a trial basis and they have some good tutorials available as well.

Many years ago, Allen Bradley ran some training courses from their premises in Sutton Coldfield. One received a pretty little certificate to nail on the wall....
