● Min. publishing interval (ms)
Here you set the minimum publishing interval that the server application of the gateway
should support. Lower values requested by OPC UA clients are not taken into account.
The OPC UA server provides the clients with the UA data in the cycle of the publishing
interval.
Range of values: 100 .. 65535 ms
Default setting: 500 ms
● Min. sampling interval (ms)
Here you set the minimum sampling interval that the server application of the gateway
should support. Lower values requested by OPC UA clients are not taken into account.
The OPC UA server of the gateway samples its internal process image with the sampling
interval.
You specify reading from the station with the polling cycle, see section Station
configuration (Page 63).
The default is suitable for most applications. A smaller sampling interval can be selected
for reading fewer data points when the polling cycle is configured with a smaller value as
well.
