KEPServerEX V6
à Note: The Alarms & Events Plug-In allows conditions to be configured through server tags. For example,
a Temperature tag can be configured through the Alarms &Events Plug-In to generate an event when the
maximum value is reached. For more information on the Alarms &Events Plug-In, contact an OPCvendor.

Optional Interfaces
The AE server interface does not support the following optional interfaces:
l IOPCEventServer::QueryEventAttributes: This interface manages event attributes, which are not
supported by the server. Attributes allow custom information to be added to an event (such as
special messages or server tag values). This also applies to the
IOPCEventSubscriptionMgt::SelectReturnedAttributes interface and the
IOPCEventSubscriptionMgt::GetReturnedAttributes interface.
l IOPCEventServer::TranslateToItemIDs: This interface allows AE clients to get the OPCDA item
related to the event. This is because in some cases, events are related to the value of a server tag.
l IOPCEventServer2: This interface allows clients to enable/disable areas and sources. This interface
is not supported by the server, because it would allow one client to enable/disable an area or source
for all clients.
à Note: The AE server interface does not support tracking events.
OPC UA
Supported Version
1.01 optimized binary TCP
Overview
OPC Unified Architecture (UA) is an open standard created by the OPC Foundation with help from dozens of
member organizations. It provides an additional way to share factory floor data to business systems (from
shop-floor to top-floor). UA also offers a secure method for remote client-to-server connectivity without
depending on Microsoft DCOM. It has the ability to connect securely through firewalls and over VPN
connections. This implementation of the UA server supports optimized binary TCP and the DA data model.
à Note: Currently, neither UA via HTTP/SOAP web services nor for complex data is supported. For more
information, refer to the OPC UA Configuration Manager help file.
OPC UA Profiles
OPC UA is a multi-part specification that defines a number of services and information models referred to as
features. Features are grouped into profiles, which are then used to describe the functionality supported by
a UA server or client. For a full list and a description of each OPC UA profile, refer to
http://www.opcfoundation.org/profilereporting/index.htm.
