  3. Hi colleagues, I have an old Melsec A0J2 on my desk. I have doubts about the correct operation of inputs and outputs. Is Melsec Medoc v2.41 the last software to use this PLC? In the program, I am looking for how to view the Online status of inputs, and how to force the outputs. I'm looking for these options and can't find it anywhere. How to possibly check if the inputs and outputs work properly?    
  4. Any old timers out there that can dust off the memories and help me program an old A0J2 processor? I can access the processor through Virtual Box DOS and MELSEC MEDOC.  I can upload the program and data registers and print everything.  The problem is that I want to change the program and having issues with the software & PLC.  The PLC has a ROM in it (ROM not an EPROM or EEPROM).  I can remove the ROM and set the jumper to RAM instead of ROM.  When I try to download the program I get "Param different" and the download stops.  I can reinstall the ROM and the PLC reloads OK and runs the program.  Where can I view/download/change the "Parameters" that the message is referring?  Do I need to clear the PLC somehow and reload everything? Any help is greatly appreciated.  Thanks in advance.
