To comply with this security requirement, each UA server instance and UA client instance must provide a trusted certificate to identify itself. OPC UA's security requires that all endpoints participating in UA communication do so over a secure con-nection. OPC UA Configuration ManagerThe OPC UA Configuration Manager assists users in administering the UA server configuration settings. L An enhanced method of discovering available information from participating UA servers. L Robust item subscription model to provide efficient data updates between clients and servers. L Secure connections through trusted certificates for client and server endpoints. OPC UA can aggregate data from multiple OPC DA sources into non-industrial systems.įor the majority of user applications, the most relevant components of the UA standard are as follows: L It provides an additional way to share factory floor data to business systems (shop-floor to top-floor). For users connecting to remote computers within the corporate network (inside the firewall) on a domain, an OPC DA and DCOM connection may be satisfactory. L It offers a secure method of client-to-server connectivity without depending on Microsoft DCOM and has the ability to connect securely through firewalls and over VPN connections. OPC UA complements OPC DA infrastructures in the following ways: It will not be a system-wide replacement. For most industrial applications, UA will complement or enhance an existing DA architecture. Although UA intends to provide a platform independent interoperability standard (in order to move away from Microsoft COM) it is not a replacement for OPC Data Access (DA) technologies.
