So if you can connect with 1 port, you should be able to connect to the other. But offcourse the settings for the ports can be different, try other baudrates. It can allso be the case that the 200 program is using the port, then you can only connect if cpu is in stop. Last possibility is that the port is defect. Regards, Marcjan

Simple two network program is there in PLC and that is for testing. so no program related to free port etc is there. 2. checked system block of uploaded program and baud rate, settings of both port are same. 3. Port is not defective because earlier version PC adapter USB is communicating woth both port. 4. Problem occured in CPU 224XP. with CPU226 it is communicating with both port. Kindly resolve the problem. Thanks
