Posted 21 Dec 2017 To the best of my knowledge, the USB port on the PLC is for programming only. Omron tools like CX Programmer, CX Integrator, etc... Share this post Link to post Share on other sites
Posted 21 Dec 2017 What Omron controller are you using? As IO_Rack has indicated, the USB port on most Omron controllers are for programming only. Regards, Garry Share this post Link to post Share on other sites

Posted 21 Dec 2017 The CJ1W-PA202 is the power supply. Is this the CJ1M? If so it has a Built-in peripheral port: Programming Device (including Programming Console) connections, Host Links, NT Links Built-in RS232C port: Programming Device (excluding Programming Console) connections, Host Links, no-protocol communications, NT Links, Serial Gateway (Compoway/F master) Garry Share this post Link to post Share on other sites
