Does Honeywell PHD support OPC UA? If so, what is the first version that supports this standard?
At this time (with PHD version 321, the PHD OPC / OPC HDA server does not support OPC UA.
It is actually surprising, with the OPC UA specification having been released many years ago, that there is so little adoption of the standard. UA has many benefits over standard OPC DA, including security.
At the Homeywell User’s group of 2016, there were no promises from Honeywell about when any Honeywell product would support UA, except a non-committing statement of, “It is definitely on the roadmap for all our products.”
Since the number of client software packages demanding OPC UA are so few, there is, likewise little demand for OPC UA servers.
