LS GMWIN v4 Software and Installation

gmwinGMWIN is the software tool that programs and debugs for all GLOFA-GM PLC series. GMWIN is capable of editing, simultaneously debugging multiple programs, and provides a simulation function to maximize user convenience.I need to talk to someone with experience on GMWIN software for LG GLOFA-GM PLCs. I'd like to know how to upload the execution program stored in a GM7 PLC via RS232C
