Need to learn AB as much as possible before Monday.

If you can get access to programs from your new company, sit and study them. See how things are done.

At my first job out of school, I was used to the way logic was done in their programs. I was pretty proficient at troubleshooting and adding new logic following the same structure. When I started my current job, things were totally different. I felt new again.
 
I downloaded that and it needs a comm program called RSLinx. I hunded around for it a bit and will continue in the morning. I have found it in a pay version only so far.

Thank you,

Ron
 
Thank you for the great info.

I'll head over to Ron's site pronto. I reviewed it briefly and it looks like great training spot.

Thanks again,

Ron
 
Did you not get linx with your logix lite

oops I have never got a free anything from AB. Guess linx would not come with it.

What was your previous software that you are proficient in. I/we might be able to share the difference

Yes, I'm a former programmer who worked on a great machine, the AS400 (and several of it's predecessors).

I once programmed in a language called RPG. It had a 14 step "logic cycle" that seems very similar to PLC's. It automatically looped and conditionally processed lines of code dependent on indicators which were set on and off or by the type of line coded.

There were lines known "Input Specifications", or I specs, for reading files or data structures, Output Specs for outputting to screen or printers, C specs for coding logic lines and so on.

You could write very tight code and get a whole lot done with very few commands. The times were changing and I never fully mastered it, but I believe I understand the concepts of plc's the better for it. If you are interested google RPG logic cycle. Seems to be related to PLC programming for sure. Input, Calculate, Output...

Thank you for the tips,

Ron
 
I'm not sure if the RSlinx installed with the lite. The lite and the simulators installed in different locations, but that usually doesn't matter. I'll have to debug further in the morning.

Thank you,

I programmed in RPG mainly. ILE RPG 400 is what it morphed into over the years. PL1 a bit, Basic a bit, Dbase3 & 4, Paradox. 4GL language SYNON. Fortran in school. Lots of different PC apps and their macro or programming languages. Cool stuff that mostly exists in peoples memory anymore...

Thanks for the interest,
Ron
 
OMG my daughter uses that. AAAAAAAAAAAAAA great machine. We were looking to help you with AB ladder we don't necessarily care about google RPG logic cycle. I think your dicked.

You perhaps are very smart, but you got yourself way over your head.

Have you ever programmed a PLC, have you any electromechanical knowledge or have programmed a single moving machine before? :eek:

Do you have electrical skills?

What will you be doing with these Allen-Bradleys exactly?

What environment, and are you familiar with it?

Welcome to the world of PLC programming.It sounds like you are coming from the computer science world so forgive me if that is not the case but this still may be useful.When I first started with PLCs I had done BASIC and C and FORTRAN and the biggest thing that took me a while to get was that you have to forget about going into a loop to wait for something to happen on a PLC. While there are some ways to do conditional exeution, in general when starting out it helpped me when I began to think of the PLC program as one loop that executes continuously. This is what we mean by the program scan. Every rung gets executed every scan. If you need to wait for a limit switch to close before turning on an output to close a gripper, you don't try to keep the program looping doing nothing until the switch closes, you just do not close the gripper and then let the flow of execution continue to the bottom of the program and start all over again.The Boot Camp stuff is great. Get the new employeer to send you to Rons class if you can. No matter how much you know about programming, learning about industrial programming from such a specialist will greatly increase your productivity. I would think your employeers payback would start immediately and for your while career there you will be more efficient so it would be time & money well spent.Embrace the cycle of the PLC.- Scan the inputs- Solve the logic rungs- Set the outputs- Repeat(thus might be slightly simplyfied but what you need to start)Anyway, good luck with the new job and just take thing one step at a time and you should do fine.
Yes, that is sound advice for anyone coming from computer programming. I'm still struggling with reworking my ideas when I think of a loop. I know they are technically possible to more or less do, but coming from a computer programming background as well, I can definitely say that the biggest difference is in dealing with loops.
 
I am just getting a head start. I don't have to learn the entire PLC world.

I have an associated degree in electronics, many years of programming experience on computers, many years of experience as an electromechanical technician for small computerized electronic machines that do not use PLC's, and am very mechanically inclined.

I have never programmed PLC's before and I just need to make a start. I would like it to be as good a start as possible. I realize it will take years to master this skill, and appreciate all your help getting me going.

I will be working in a small factory with AB PLC's.

Thanks for any ideas you can give me,

Ron
 
The AS400 was a great machine. Shops went from 40 people down to 5 or 6...

I think you misunderstand my goals. I just need a start. With your help and the others here I have already begun to learn PLC's and ladder logic.

Thank you,

Ron
 
RSLinx Lite is free it comes with the free ver of RSLogix at the link below. See picture for the one with RSLinx

http://www.ab.com/programmablecontrol/plc/micrologix/downloads.html

And a "Getting Started Guide" for RSEmulate. See link

http://literature.rockwellautomation.com/idc/groups/literature/documents/gr/emulat-gr002_-en-p.pdf

And you are going to do all this before Monday?

Hi Mickey,

I just need a start. If I could get the environment going and do some very basic work by Monday that would be great. Am I asking too much of myself?

Thank you,

Ron
