By default the error mode will be NORMAL. To switch to LEGACY mode for data errors, start
the DCC Slave Configuration utility and change the item OPC Configuration → Global
Parameters → Error Mode.
8.5.2 Data Item Properties
All Data Items will have an associated set of OPC Data Properties.
These will always include the six standard OPC properties:
• 1 Data Type
• 2 Value
• 3 Quality
• 4 Timestamp
• 5 Access Rights
• 6 Scan Rates
The standard Timestamp property is the time the data item was read from the RTDB,
not the time of update from the gauge.
Unless otherwise stated, all data items have Access Rights of READ ONLY.
Many items will also have extra properties defining configuration data which only
applies to that item. These generally define certain configuration data that is usually
fixed or change very infrequently, such as alarm limits, units, manual values etc.
