I need help, I wrote the code for Arduino using the OPC library and software ArduinoOPCServer. On some SCADA systems and, for example, in Matricon OPC Exp. it is automatic to be this server and pull tags from there. How do I do it in Ignition SCADA?

Hey @Oleksandr_Kononenko,

If you are trying to connect Ignition as an OPC UA client to the ArduinoOPCServer, those settings would be configured within the OPC Client section of the gateway (Config \> OPC Client \> OPC Connections).

Here is the documentation guide for configuring 3rd party OPC UA connections. ([Client Connection](https://docs.inductiveautomation.com/display/DOC81/OPC+UA+Client+Connection+Settings))
