PC-PLC CP1E - USB-to-SERIAL cable

6 posts in this topic

Posted (edited)

Hi,

 

I have a self-bought usb-serial cable converter for CP1E. Currently can't connect to my PLC using PC.

CX-One says "Failed to the PLC". I am supposedly to use "SYSMAC WAY" as my Network Type in PLC settings?  

EDIT: The CPU type is N30

 

I've checked the following settings:

1) COM number is correct ( as checked from windows Device Manager side)

2) Cable driver is installed, there is no "unknown" driver in my windows Device Manager

3) My RS232C LED in PLC is not lighted up.

 

Any other suggestions to check settings ive missed out would help, other than buying a new cable for the moment.

 

Regards,

Summerstone

What cable do you have connected from your USB-Serial adapter to the PLC?

You cannot connect directly to the PLC serial port. You'll need a Host Link cable. You can make this yourself.

I only use direct converter cable. PC > USB-Serial Cable > PLC

How do I get the pinout for this Host Link Cable?

It should be in the appendix section of the CP1E manual, downloads section here at MrPLC, or check this post:  http://forums.mrplc.com/index.php?/topic/35120-cj1m-cpu13-etn-connection-issue/

The Host Link cable is the same for nearly all  Omron PLC serial ports. If fact, most refer to them as Host Link ports. Default settings are 9600, E,7,2.

Ok I saw the post uve linked, and also checked the appendix manual. Let me get it straight, so ill have to make it like this:

PC > USB-Serial > Host Link Cable > PLC

Correct?
