Hi,

When writing a java module with Ignition’s OPC-UA server it’s possible to expose tags using the simpletag provider.

As far as I understand, with OPC-UA standard comes the possibility for object to expose methods to OPC-UA clients instead of just exposing tags variables.

Is there a way to expose methods to clients when writing a custom module in java?

Best Regards,

Hi Kevin,

Thanks for the input.

Just to be sure : Is there another way to expose methods then (I mean without java) ? Or this feature is just not implemented at all within the server?

Best Regards,

It’s just not implemented in our server at all.
