micrologics 1000 eeprom program extract

[professor_jonny 1]

Hi I have a micrologics 1761 plc and it is faulty it has an embedded eeprom that contains the user program is there some way to extract the user program from this dead plc?

 

Am I able to read out the program with an eeprom reader or is it in some way encrypted on the eeprom or converted in to machine code or something like that?

 

the plc was on a machine that was imported and we have no access to the original program we would like to transfer it to a new plc or at least figure out how it works so we can write a new program if possible.

The Micro 1000 also had the optional handheld programmer  http://fr.rs-online.com/webdocs/0027/0900766b800270f4.pdf

Will the processor power up, albeit faulted?  If so, you may be able to upload the EEPROM contents.  http://www.lehigh.edu/~inconsy/lab/css/ME389/manuals/MicroLogix_Manual.pdf

What would you do with the contents of the EEPROM?  You could obtain a working Micro 1000 (yes they are obsolete Silver Series, but are still available as NOS [new old stock]), pop in the EEPROM, power up and go to town.
