cx-one txd problem

Hi all!

I'm trying to send 1 byte data to pc with CP1E-N built-in rs-232

I've connected right pins as omron plc needs.

Now here is the situation:

When the "some condition" is true i can monitor that D0017 has been changed to #0015 it is ok. But It stops Transmitting.

I'm stuck here please help.

What device are you trying to communicate with?

Please post your cable pin out.

How is the TXD instruction programmed?
Need to understand the control word settings.
Also the number of bytes can trip you up.

How is the RS232 port configured in the PLC settings?

Communication is between "CP1E-N30DR-A" and "OEM PC Com Port"

Rs-232 Configuration is :
9600,8,N,2
Mode: Rs-232C
Start Code: Disabled
End Code: Received Byte=1
Delay: 0 ms

My TXD setup D word is: D20=0101
My RXD setup D word is: D0=0101
My TXD send D word is: D17=0034, 0035, 0036 (I change it with mov)
Results for:

PLC ===> PC
0034 ===> 0020
0035 ===> 0020
0036 ===> 0024

My wire setup is:


My application is:

What program are you running on the PC to read the com port?

My thought is you may need to set an End Code for the PLC port so the PC knows the string is complete.
