Read [this thread](https://discourse.nodered.org/t/mitsubishi-q02cpu-comm-through-q71e71-100/50842/11) and [this thread](https://discourse.nodered.org/t/mitsubishi-q-series-node-red-help/33337/5) - there are many clues in there of what things to look at and what settings to try out.

Also, read through the [closed issues](https://github.com/Steve-Mcl/node-red-contrib-mcprotocol/issues?q=is%3Aissue+is%3Aclosed) on github (lots of similar info in them)

If you still dont have success, share detailed information about...

- what you connect to (PLC Ethernet port or E71 card)
- IP address settings
- Open Port settings
- Screenshot of config node
- Can node-red server actually PING the PLC
- etc

I used PLC Ethernet port  
Host - 192.168.1.39  
for port I used [Zenmap app](https://discourse.nodered.org/t/mitsubishi-ethernet-communication/50072/4) and found 5 open ports

UDP - 5001,6,8,9  
TCP - 5007

while using UDP I kept  
Frame - 4E  
Protocol - UDP  
PLC Type - Q

& when using TCP  
Frame - 3E  
Protocol - TCP  
PLC Type - Q

And only with TCP it showed connected. But when injected I get error : timeout

apart from above I tried with countless combinations but no success 😭

I've gone through the [post](https://discourse.nodered.org/t/mitsubishi-q-series-node-red-help/33337/5) and I think changing open system setting from **MELSOFT connection** to **MC protocol** can work.

But Is there a way to communicate through MELSOFT connection ?

Not with this node no. I couldn't get it to work.
