That should work. Tell us more about how you are trying to communicate. Does your PC have a real serial port or are you using a USB to serial adapter?

RsLinx settings and what driver are you using? Do you know how the port on the PLC is configured?
 
I am using rslinx v2.57 version and i am using the serial cable with db-9 connectoers not the usb to serial cable
i am attaching the print screen of my setting

i can also see the node-00 when i will take the driver AB-DF1 AND THEN CLICK THE WHOS ACTIVE GO ONLINE

I AM ALSO ATTACHING THE PRINT SCREEN OF IT

Is anything else normally connected to the port? It is possible someone has configured the text for something other than the default driver.

I would try connecting via Ethernet and uploading the program to view the serial configuration.
 
atually i can go online using the ethernet communication it is working fine but i want to go through serially cable(RS-232 PORT) only because i want to communicate my PLC with other microcontroller
i have tried to read the manual but they have only written about channel-0 not channel-2
is there anything in ML-1400 that i have to change my configuration if i have previously go online through Ethernet??
i am really confused???

waiting for your reply

Go online with your Ethernet connection. Go to communication settings from the project tree and see what the settings for channel 0 are. Either post a screenshot or let us know.
