Hi

We are looking into diode technology (unidirectional gateway) to implement seamless one-way only data transport from OT to IT, to enforge the protection of our OT systems.
One of the vendors claim to support OPC UA, "all functions". Any of you guys with experience from routing OPC UA through such diode technology.

UA PubSub is perfect for network diodes.

Regular UA is request-response and can't work through a network diode.

You should ask this vendor to explain what they are really doing.
