We have an old piece of equipment that utilizes (2) Modicon Micro 110 CPU 612 03 PLCs that control it.

Can anyone recommend the most cost effective way to gain access to this PC, i.e. software, version, cable, etc.?

Thanks.

 

My favorite software for this purpose is PLC WorkShop from http://www.fast-soft.com/ A local engineer may do the job for you less than the cost of the software.

The absolute low cost method would be to find a copy of Modsoft Lite and install it on a laptop with its date set back to 1999.

The big problem with losing the original PLC docs is the the program will have no naming of the contact and register functions, and no network comments.
The 612 is a great PLC, I use a number of them.

Good luck.
