UAMonitoredVariables

DataType

Description

Values

ARRAY OFVendor specific

Vendor specific.

Array shall have the minimum length as UAMonitoringParameter QueueSize

TimeStamps

ARRAY OFVendor specific

Shall be DT or LDT. The recommendation for new implementation is to use LDT. It is expected, that the SourceTimeStamp from the server is returned.

Optional – If exists it shall have the same length as the Values array.

NodeQualityIDs

ARRAY OFDWORD

Contains an error code for each element of the Values array.

Optional – If exists it shall have the same length as the Values array.

In case of “Overflow” Bit ‘7’ will be set if queue size is greater than 1. If this bit is set, not every detected change has been returned since the Server’s queue buffer for the MonitoredItem reached its limit and had to purge out data and the MinLostValueCount from UA_MonitoredItemAddList will be incremented by one (1).

NewValuesCount

UINT

Count of Values (Vendorspecific) which were updated starting from the lowest element of the Values.
