Hey All,
We have an older machine, built in 2001, using a Mitsubishi PLC,(MELSEC FX1N-60MR), something is not working correctly and I'm trying to figure out why.
I unfortunately do not have the software or cable needed to access this plc.
A little research shows the current software would be GX-DEVELOPER-FX, and it looks like the cabling will consist of a F2-232CAB-1 (9pin to 25 pin), a FX-232AW (232 to 422 converter), and a FX-422CABO (25 pin to small round connector).
Can anyone verify this?
I've also seen reference to a free "Demo" version that Mitsubishi once offered, but they dont anymore? Seems it was fully functional but limited to 1000 lines (my program is about 700 lines).
Does anyone have info on this or know where I can find it?
I do have a print-out of the ladder logic, and I think I have it narrowed down to about a half dozen lines of logic, I can see the real world inputs I need but have no way to see the internal bits or a timer associated with this chunk of logic.
If I cant access what I have, my next thought is to transcibe the logic into something new, and replace this old PLC. the logic looks pretty straight forward and should be easy enough to replicate, but I see one instruction that I am not sure of (I did find a list of the Instruction Set, but have not yet found this).
Can anyone tell me what a ZRST is?
