Old machine

Hello Folks,

I've been here in this forum in the past getting some help from people in this forum about PLC. I'm intermidiate student without that much experience as most of the people in this forum.
I have a machine that has been down for a year already. When I was asked to turn it on, I found it without responding, I checked the PLC status light and found the error indicator flashing. PLC is dead or no more program stored.
I would like to try to make it work, but I need to get an Allen Bradley PLC because the one it has is an LG and I dont have software and cable for it.
I do have for AB.
Can I feel free to ask any question to any body if I get stuck with this?

Thanks.

Jose

Of course.

Do you have a copy of the original LG program? That will be a huge help. Also, which LG model?

Thank you Alaric,

I don't know what AB model to get if the micrologix 1200 or the 1500.
I'll let you know.

Thanks

Jose.

Before we jump the gun, take a look at this thread: http://www.plctalk.net/qanda/showthread.php?t=7311
It has links to cable diagrams and the software. It appears that you can download the software free.

Thanks for the information Alaric.

Do you think the KGLWIN programming software supports the LG K7M-DR305?
I see alot of K... series that the KGLWIN supports but I don't see the K7M.

Thanks,

Sincerely, Jose.

Sorry Jose, I'm not an LG expert so I can't answer that question. There are members here and at the MrPlc.com forums who do know LG PLCs, maybe a thread asking that question with LG in the title will get their attention.

Thank you again Alaric.

I will research that myself. I will let you know about my progress.

Regards.
Jose.
