Initially, the connection is offline and shows an error as shown in the picture. Then, about 15 minutes. I go out and then come back. It is connected successfully. I Try removing the RJ45 PLC jack and plugging it back in. But the red node switches to "Offline" and reports the "error Error:write enconnreset". The question is: what is the error here? please help ------------------------------------------------------------------------------------------ Split from S7-200 to IOT 2050 using ethernet.

You can try to increase the timeout value to 4000ms in the S7 node configuration and make sure that "PUT/GET communication from remote partner" is enabled on the PLC. Is your IP configuration correct? Maybe you can share some logs from your node-red and your flow. BR
