The best way is to use MC Protocol. 1. Connect PLC with PC via CPU programming port. 2. Set up the QJ71C24N-... communication channels by switches settings of the module in Project-PLC Parameters with GX Developer or GX IEC Developer software. 3. Download project with updated PLC parameters into PLC and run it. 4. Connect PLC with PC via QJ71C24N-... RS232 channel. 5. Create new connection in MX Components between PC and PLC with MC Protocol.
