About UaGateway
UaGateway is built to migrate classic COM and DCOM based OPC servers to OPC Unified Architecture. It works as a wrapper and proxy, so existing OPC DA clients keep working while OPC UA clients read the same data. The product page says connections to underlying servers can be added at runtime without restarting the gateway, and that the gateway is configurable through OPC UA methods.
Features are sold as individual license keys. The page lists a base module for classic OPC DA 2.05a and DA 3.0, a secure UA tunneler, an outbound reverse connect option, a store and forward datalogger archive and custom address spaces for companion specifications. The UaGateway is a 32-bit Windows application that also runs on 64-bit Windows under WOW64. The page offers an evaluation download without naming its term, and it lists no prices.
