PPC, SECS communication program in C for Mitsubishi PLC

[Marius Golban]

Hello,

I am working in microprocessor industries, now I am doing reverse engineering for PPC SECS communication program in Visual C++ 6.0 for Mitsubishi PLC(Model Q50UDEHCPU). Did anyone from you have worked with this program PPC? I need to find out the what are doing each function from this program? Like hostproc, data, mainproc, otherproc, plcproc, qbproc queue, offline, send_c, QBFFunc32.

What exactly is it that you need help with? "PPC SECS" is not a Mitsubishi C controller, and the Q50UDEH CPU is a standard ladder logic controller. Not sure what you're asking here, and from/to what kind of equipment.

Hello,

Well the PPC is the installed on the PC from Mitsubishi PLC RACK. Is used to communicate from PLC towards Host, and it has drivers for the BUS communication.  The PPC program is under C code, but is using PLC windows drivers.
