Omron binary format program

[Guest Ekkho]

Hi, I need to remake a system which was built around 1988 with Omron PLCs, which is no longer supported and don't have documentation on its program. The only information I have is in binary format. I wonder if the experts here has any suggestion on how I can I read this binary format into a program that can be understood. Thanks in advance

Can you send the binary file to the forum? May be exploring it by an Hex editer helps, may be we can find some hints for PLC type, software version etc.
