OPC UA Server

System manual

2696790000/02/04.2020

Possible configuration entries:

Name Description

MinPublishingInterval Minimum time interval in milliseconds, data type Double

MaxPublishingInterval Maximum time interval in milliseconds, data type Double

Information

The minimum time interval chosen should not be too small, since the OPC

UA server can reach a high load by answering these requests if there are

several clients.

When sending a request (CreateSubscription), the client submits a de-

sired time interval. The server checks whether the required interval is within

the configured limits. If this is not the case, the limit value set is rejected by

the server.

Example

[OpcUa.Subscription.Publishing]

MinPublishingInterval=100.50 // double

MaxPublishingInterval=10000.50 // double

The client requests an interval of 70 ms. The server responds that only a

time interval of 100.5 is possible.

Recording values (samples)

The default recording intervals are set to 50 ms, 100 ms, 250 ms, 500 ms,

1000 ms, 2500 ms and 5000 ms. The intervals can be changed via the con-

figuration, the data type is Integer:

[OpcUa.Subscription.Publishing]

[OpcUa.Subscription.Sampling.Intervals.Interval:0]

Interval=100 // int32 - ms

[OpcUa.Subscription.Sampling.Intervals.Interval:1]

Interval=20 // int32 - ms

[OpcUa.Subscription.Sampling.Intervals.Interval:2]

Interval=500 // int32 - ms

Several recording intervals can be defined by increasing the interval number.

Every interval number must be unique.

When sending a request (CreateMonitoredItem), the client submits a de-

sired recording interval. The server checks whether the required interval is

within the configured limits. If this is not the case, the closest value set is re-

turned by the server.

Example 1 (Standard configuration)

Standard recording intervals: 50 ms, 100 ms, 250 ms, 500 ms, 1000 ms,

2500 ms and 5000 ms

The client requests an interval of 70 ms. The server answers that the moni-

tored object (MonitoredItem) recorded at intervals of 50 ms.

Example 2 (example configuration)

Configured recording intervals: 20 ms, 100 ms, 500 ms
