OPC HDA data connection properties

AccessFailureLimit

The number of times that the connector cannot succeed to access the external server before AVEVA™ Production Management restarts the connection.

Integers

ComputerName

This is the network name of the external computer that processes the data requests. Do not prefix the computer name with a network path like \\<ComputerName>.

Any valid computer name

ConnectionState

The current state of the connection to the external server.

Open, Closed, Broken

ConnectionTimeout

Enables you to modify the amount of time that the connector attempts to make a connection before it times out. If a timeout occurs, the connector is put into an error state and an event notification is issued.

DisconnectBehavior

Specifies the method of disconnection from the OPC Server.

The default behavior is to disconnect in the normal way (FollowSpecification). However, for AVEVA Production Management servers that connect to an OPC Factory Server (OFS) specify this setting as Fast.

FollowSpecification, Fast

EnableHealthCheck

Enables or disables health checks; that is, a periodic ping process that monitors connection health to verify valid connectivity.

True, False

HealthCheckPeriod

The amount of time between health checks.

[hh:mm:ss] Minimum is 1 second (00:00:01). Maximum is 30 seconds (00:00:30).

HealthCheckTimeout

The amount of time to wait for a healthy connection before a non-working connection is verified.

[hh:mm:ss] Minimum is 1 second (00:00:01). Maximum is 23 hours, fifty nine minutes, fifty nine seconds (23:59:59).

OpcHdaDataSource

This value is display only. It is the path structure and name, in dot notation, of the data source that the connection belongs to. It represents the position of the item in the project hierarchy. The full name identifies the data source in code.
