Posted 19 Mar 2012 Hello, I'm using Omron CP1E-N30 plc. First port is a serial port, that is connected to an HMI screen (NQ3) Second port is used for Modbus communication to inverters. Programmation is done over USB. I want to connect remotely on this plc. Does anyone has a tested solution to connect to OMRON PLC remotely over USB? I tried a USB server (USB port made available over a network). This software recognises the USB device as an Omron PLC, but when i try to connect in CX-Programmer, i get a BSOD (No_more_IRP_Stack_Locations) already thanks.
