[indra 0]

Hi, We have CPU MITSUBISHI type FX1N-24MR. We have it for our new roofing forming machine from vietnam. At the moment we have problem but I can not ONLINE the PLC because looks like protected by PASSWORD. Does anyone knows how to open / by pass this PASSWORD then I can go trhough the LADDER program ? This machine we bought without drawing and ladder plc printout, just installed then running. only simple electrical diagram but also in Vietname language. we tried to contact this suplier but never get any reply yet. indra

If you have read any previous posts here about circumventing passwords you probably already know that you are barking up the wrong tree. If you cannot get the password than you can clear the plc memory and re-write the code. -plcdp

Indra, as plcdp said, you cannot ask about hacking of passwords in these forums. Your only choices are to get the manufacturer to fix it, or to erase the PLC and rewrite the program.

There is another choice. Why don't you google "Mitsubishi Keyword" instead of asking questions nobody will answer here? Edited 21 Aug 2011 by Sergei Troizky
