Siemens software SIMATIC NET and AXC F 2152 can not communicate through OPC UA

Hello , We are using Siemens software and AXC F 2152 to communicate through OPC UA. Siemens software：SIMATIC NET V15 ,OPC SCOUT V10. PLC: AXC F 2152 (2019.6) In our test, we found that OPC SCOUT can communicate with AXC 1050, but only servers can be found when communicating with AXC F 2152, but data communication can not be established. In addition, we found that OPC score does not support X509 certificate mode. I know that AXC F 2152 OPC UA supports x509 certificates. Does AXC F 2152 only support x509 certificates, or does it support other ways? If it needs to communicate with Siemens software through OPC UA, is there any other way? Thanks a lot!

Hello, Please see this discussion: https://www.plcnext-community.net/index.php?option=com_easydiscuss&view;=post&id;=2318&Itemid;=224⟨=en In summary:

If you disable User Authentication on the Web-Based Management page, and then restart the controller , you should be able to connect to the OPC UA server without user credentials, and without encrypted traffic.

- Martin.

Hello Sir, I’ve tested it, but I still can’t set up normal communication. PLC has been powered off and restarted.

Hello, I see that the Endpoint URL is opc.tcp://axc-f-2152-1:4840. Do you have a DNS server or a hosts file that maps this DNS name to the IP address of the PLC? If not, then please try changing the Endpoint URL to opc.tcp://192.168.1.10:4840. (or whatever the IP address of your PLC is). - Martin.

Hello Sir, Changing the DNS name to IP can solve the problem, and 128/256 encryption mode can also be used. Thanks very much!
