Troubleshooting an OR Industrial Computer PC

You don't give us much to go on.........so until you give us more conditions heres a basic.

Is it plugged in?

Thanks for the fast answer.

This was the CPU of an AUTOMATA PC in a Grecon Cutting Machine. The Automata's rack (VME Bus), power source plate, and I/O plate are working fine (I have a 2nd Grecon Machine, so I exchanged CPUs and everything worked fine with the other CPU). Of course, this faulty CPU didn't work in any of the PCs. The CPU's POWER LED turns ON, but I don't get anything on screen, not even the startup process of the OS.

I already tried changing the HD, processor and RAM, unpluging the floppy disk, and still have no response.

I hope this helps you

these are quick responses

are any pins bend or missing on the connection slots/cable's?

Is it a separate screen or is the screen intergrated into the CPU? Check the cabling of the screen if you can, and also the power.

I'll try to come up with a longer list

Hi,

I work with abellora, I will be following this issue.

Answers:

Fisrt of all... yes. I plugged it in :)

No, no pins missing or bend.

Sorry, what I meant with "screen" was a regular 14" PC monitor, as this runs a DOS application. And yes, the monitor works fine, as I tried it with the other CPU.

Sadly, I dont have any wiring diagram or manual of this plate

Thanks,

Fala

Yes questions are very basic,

but to trouble shoot without documentations one starts from the beginning

I know what your experiencing having been there

No problem!!

Ask me whatever comes to your mind.... Maybe you solve my problem with a basic question!

What you are talking about here is a cheap old system unit. All you need to know is what your input and output requirements are and you should be able to substitute an old laptop that is functional and can run DOS programs. When you say CPU are you talking about the actual CPU chip on the mother board or are you talking about the mother board itself. If you are talking about the CPU chip on the mother board this would be a simple fix if it is the type you can plug in. Unfortunately, some of the old mother boards had CPU chips that were soldered into place. If that is the case, you need a new mother board (which may no longer be available). What you probably need is a computer service guy that can analyze and solve your problems on site.

Very good, I have'nt thought of that, Check your operating system, to make sure the it is a compatible dos system. I had software that ran on DOS, but in later verisions that software did not run, it basically lock up the system......Software that did this was an early version of MathCAD and another that I don't remember.

Would make it easier, even to bring it in.

It's not so easy, because besides the motherboard the are some other boards on the PC Rack, and the comm bus is VME. I can't replace the original PC with a regular PC. It's not only a software problem....

Yes, I need some guy experienced in electronics/computation, to check the board and find the error in it. Or, what I'm also trying to do, is to find someone who is familiar with OR Tech PCs who could give me hand.

Have you tried contacting Grecon?

When we designed and built machines that used a program for stepping motors and solenoids we used a vendor to make custom mother boards and motor driver boards. You could not buy these boards from our vendor, just from us. Likewise the programming was on an EEPROM which you could only get from us. Check with your equipment manufacturer.

Is it possible for you to send a picture with peripherals removed from the board?

If it is possible to remove the peripherals and work with only the board you may be able to rule out peripherals by swapping with known good board. If you need a board there may be no way around this but it is possible to trouble shoot a board if you know what to look for and have the right test equipment. Would be best done by someone who specializes in this or the original manufacturer.

Hello

I have been looking all over for information on the Grecon PC you posted about in 2009. The hard drive went bad and do not have the installation disk.

Do you still have these machines? I have tried contacting the manufacturer with no luck.

Thanks!
