In addition, for each endpoint a server can also support different ways of identifying and authenticating users.<\/p>\n<p>Currently, <strong>E3<\/strong> allows a connection only using the <strong>Binary<\/strong> <strong>TCP<\/strong> mode. For this mode, <strong>E3<\/strong> supports security modes defined by the OPC UA standard, with several combinations of security policies. For authentication, E3 only supports <strong>Anonymous<\/strong> and<strong> User and Password<\/strong> modes.<\/p>\n<p><strong>NOTE:<\/strong> The OPC UA Servers window lists all protocols and security modes, for user information. However, only E3 compatible modes can be selected.<\/p>\n<p>When selecting an <strong>E3<\/strong> compatible endpoint, the <strong>EndPointURL<\/strong>, <strong>SecurityMode<\/strong>, and <strong>SecurityPolicy<\/strong> properties of this object are automatically filled in.<\/p>\n<p>If the <strong>UserName<\/strong> and <strong>Password<\/strong> properties of this object are left blank, <strong>E3<\/strong> uses an anonymous connection with a server. Otherwise, E3 sends these property values to a server, which must support that type of authentication on the selected endpoint.<\/p>\n<p>In this object users can configure several time-outs for an OPC UA connection. These time-out limits (the TimeoutCall, TimeoutConnection, and TimeoutSession properties) are always in milliseconds and they must be set according to communication performance, which may be limited by a server, by a network, by machines executing a client and a server, and even by operations performed on a client. These settings must be performed on a case-by-case basis and these property values are only suggestions.<\/p>\n<p>In <strong>E3 Studio<\/strong>, communication with a Driver can be activated by selecting the <strong>Activate Communication <a href=\"http:\/\/kb.elipse.com.br\/wp-content\/uploads\/2020\/04\/10611\/5.png\"><img loading=\"lazy\" class=\"alignnone size-full wp-image-10623\" src=\"http:\/\/kb.elipse.com.br\/wp-content\/uploads\/2020\/04\/10611\/5.png\" alt=\"\" width=\"6\" height=\"9\" \/><\/a> <\/strong>option on object&#8217;s contextual menu.
