Hello everyone,

I'm trying to replace a Siemens PLC with AXC F 2152 instead, since I believe we can benefit from its features. The idea is to communicate this PLCnext and WinCC Adv via OPC UA, as I found somebody else could get it to work (unfortunately that's not my case).

When I try to set the address of the variables, I receive the next error message (seems like it can't find OPC address):

Here are some screenshots with the settings made in both programs (TIA PORTAL and PLCNEXT)

I would appreciate if you could help me to determine whether PLCnext part is well configured or not. For example, I couldn't find where to change the default port (consequently I don't really know if it's 4840, 4843 or other). Also we tried enabling/disabling all the SHA certificates, please disregard if I left any of them unchecked in the screenshots.

If anyone has attempted this communication before, any leads or suggestions about the errors I'm getting would also be highly appreciated.

Thanks in advance for your time.

Best regards,

Hi javierez,

unfortunately we do not have WinCC Adv and can not give you a step by step guidance, but as WinCC should work as a std. client it should not be too difficult.

Please try the following to drill down were the issue is and were we maybe can assist:

  • Verify the general UA configuration and the availability of the PLC. You can do that at best by following this tutorial using the UA Expert test client PLCnext OPC UA with UA Expert
  • If that works, please deactivate the user authentification in the PLCnext WBM and retry the connection with WinCC
  • If this works ether, it is likely that you have to confirm somewhere in WinCC the self-signed certificate from PLCnext. This should be than an easy answer from the Siemens support team.

I hope this helps.
