OOPC UA nodes are user configurable and can be imported and exported via a csv file. Refer to the
Process data map to configure user nodes.
The "Write Enable" check box enables outputs to be written to by OPC UA.
The "Buffer Enable" check box enables buffering of the selected node.
An adjustable data buffer is available via OPC UA for up to 1800 bytes of data and a sampling rate of
100 ms or longer.
Parameters Description
Data buffer Enable or Disable
The data buffer array can be enabled or disabled for each OPC UA
node.
Historical Data Buffer Sampling Cycle
Sampling cycle time for the buffer. The parameter is applicable for all
nodes which enabled the data buffer.
Number of data blocks
The number of points stored in the buffer. The parameter is
applicable for all nodes with the data buffer enabled.
The time stamp is LDAP/Win32 format. To convert from the buffer data to a time, the bytes must first be
combined. The resulting decimal value is the number of 100 ns passed since January 1st, 1601.
The example is shown in the following table.
