Tried two different PG`s and no way can i connect to the 224.

If it is configured for freeport then you will need to put the plc in stop mode first. If you have RSLinx make sure any drivers are stopped. Also make sure your not running any software that would use the comm port (ex HMI software)

Not sure about that, but i have had no issues connecting to other 200`s, and have ensured there are no other drivers in use, as i said, the scenario is identical on two different PG

It tells you the port is busy when you are on the communication screen and double click to refresh or when you are trying to go online?

I'd say the port is configured for Freeport.
Put the PLC in STOP mode and give it a shot.
If you manage to go online, that will be your answer.
As you mentioned, the PG works with other stations/PLCs.
If you are running RSLinx as a service your serial port is definetely hijacked by RSLinx.
EDIT:Never mind the RSLinx stuff, it is a PG

Node number

Is has been a long time since I have worked with the Microwin 200 series, but i think that I remeber having the same problem form time to time.

What I found was that the node number on the PLC was the same as the one on the PC.

Try to change the node number on the PC.

So far I understand you can have more than one device after the PC adapter where each device require its own node/device number.

I hope this will help you.

on my opinion there are 3 available reasons for this:
1. PPI port is configured as free port.
2. The PLC and PG using the same address
3. The PLC and the PG are not using the same baud rate
I think that you can find enough infomartion about these problems using the SEARCH

2.PLC address 2, and PG address 0
3. tried all baud rates available.

Thanks,

Chris

sorry,
Adress 0
Remote 2
Interface CP5611
Protocol Auto
Mode 11-Bit
HSA 126
Baud rate 9.6

These settings work on all other 200`s, except this one

Cheers

1. by default the communication port is PPI, but if you connect for example a printer. you have to configure it as freeport and it's no more accessable as PPI and you cann't communicate with the PLC exept ....

Tip
Freeport mode can be controlled using special memory bit SM0.7, which reflects the current
position of the operating mode switch. When SM0.7 is equal to 0, the switch is in TERM
position; when SM0.7 = 1, the operating mode switch is in RUN position. If you enable Freeport
mode only when the switch is in RUN position, you can use the programming device to monitor
or control the S7-200 operation by changing the switch to any other position.

2. how you are sure that the PLC port is 2 ?!? you've said that you never went online. Change the PG number !!!
3. how you change the baud rate .. from the PG ?!?


and what PG cable and card you are using.
