When Connecting to PLC Server I Get an 0x8005000 Error
Posted: 09 May 2021, 15:54
Dear all,
I get the same error trying to connect to an OPC UA server on a Siemens S7-1513 PLC (firmware 2.5). The OPC UA expert is the Ubuntu version working on Ubuntu 18.04 .
The OPC UA expert file is UaExpert-1.5.1-331-x86_64.AppImage. The file is executed using the run command after right cliking the file.
As proposed in an other post I tried to record with wireshark.The server is located on IP 172.20.1.99 and the OPC UA expert on IP 172.20.1.197. Below the export from wireshark (as csv) after an attempt to connect to the server:
"No.","Time","Source","Destination","Protocol","Length","Info"

"1301","1218.751834713","172.20.1.99","172.20.1.197","TCP","60","4840 > 60740 [RST, ACK] Seq=1 Ack=1 Win=0 Len=0"
We can see OPC UA expert client sent 3 frames, each time from a different PORT and the server answer to the right port.
Did somebody find a solution for this problem or could give me a hand ?
Many thanks for the attention.
