OPC UA servers

FactoryTalk Alarms and Events

supports tag-based, device-based, and OPC UA alarm monitoring. An OPC UA server is required for OPC UA alarm monitoring.

FactoryTalk Linx

OPC UA Connector acts as a proxy between the OPC UA servers and a

FactoryTalk

application, and aggregates the alarm data and delivers the alarm information to

FactoryTalk Alarms and Events

.

OPC UA alarm monitoring

For OPC UA alarm monitoring, at least one third-party OPC UA server must be able to communicate with the third-party devices that you want to monitor for alarm conditions. Then, add

FactoryTalk Linx

OPC UA Connector to an application or area. After defining an endpoint URL to an OPC UA server and enabling alarm and event support,

FactoryTalk Linx

OPC UA Connector routes the alarm information to

FactoryTalk Alarms and Events

.

At runtime, use

FactoryTalk Alarms and Events

objects embedded in the graphic display to interact with alarms coming from OPC UA servers.
