Other UniInt parameters

Other optional parameters that can be configured on the UniInt tab include:

Enable PI SDK

By default, the PI SDK is disabled. If the PI SDK is enabled, the ExDesc tag attribute can be 1024 characters long instead of 80 characters long. In addition, the excmin and excmax tag attributes will be full 32-bit values, and the point source can have more than one character. To enable the PI SDK select the Enable radio button in the PI SDK section of the UniInt tab. (/PISDK=x)

Queue Data

Exceptions can be queued before they are sent to the PI Data Archive node. Queuing exceptions causes the interface to be more efficient, if the interface is on a separate computer from the PI Data Archive. However, it will slightly delay the update of the snapshot value if the data rate is low. The maximum queue size is close to 4000 bytes. The queue is flushed between scans if it is not filled. To use this option check “Queue data” in the Data Handling section of the UniInt tab. (/Q)

Write Digital State to Tags on Shutdown

The interface can be configured to write a digital state to each PI point serviced by the interface when the interface shuts down. To use this option check “Write status to tags on shutdown” in the Data Handling section of the UniInt tab and select the required digital state from the dropdown list. If this option is not checked nothing will be written to the interface points when the interface shuts down. (/shutdown=digstate)

Ignore Server Status

If the OPC server does not go to the OPC_STATUS_RUNNING state when it is ready to send data, enable this option to direct the interface to attempt to communicate with it anyway (/is=Y).

No Timeout

The interface can be configured to not write I/O timeout errors when the interface has lost its connection to the OPC AE Server. Set this option when configuring server level failover (/NT=Y). If interface level failover has been configured then this option is ignored, and IO Timeout will not be written to the PI tags.

Reconnect to Server Delay (sec)

Specifies how long to wait, in seconds, before attempting to reconnect to the OPC Server if the connection is broken.

Additional Parameters

This section is provided for any additional parameters that the current ICU Control does not support.
