Mitsubishi PLC's & ActiveX


Thread Starter

Paul Miller

Ive got the control logic for a program in c++ now I need to get it to operate some I/O. Does anyone know of an (free is poss) ActiveX component that will handle the comms with my PLC, so I can just tell it to SET Y7 for eg. and it will do that. If not, any ideas ? TIA

You can use Windows API of Serial Comunications functions and directly operate it using format as specified by RS-232 communication booklet of Mitsubishi or caontact me for further assistance. Else you can use Communication Active control

I have programmed the Mitsubishi PLC in VB using MS Comm Control with RS 232 Manual. If you want code in VC or VB please contact me.
I am trying to write a VB application to communication with a mitsubishi A1SJ71UC24-R2
module and would be most grateful if you could
Email me any working source code you has

Many Thanks
