On this node, you can adjust the parent settings for using the OPC DA interface.

There is a separate configurations dialog for OPC UA.

You can enable and disable the OPC server here. The disabled status is indicated by an icon (white cross on red circle) in the tree on the left.

Only the number of the maximum permissible OPC clients that can be connected to ibaPDA at the same time must be set at this point.

This setting serves to prevent overloading the resources of ibaPDA by too much OPC communication. The default setting is 64. Only increase the value when absolutely necessary.

The other fields show different actual values for OPC communication.

In addition, you have the option to suppress OPC alerts.

Note
	The tags in the OPC server will be updated like outputs of ibaPDA. Thus, the fastest update cycle derives from the least common multiple of all module time bases or is at least 50 ms respectively.

All other settings for the OPC communication are made in the interface and modules.
