Configuration strings for PI point data references

The attribute configuration string for PI point data references must contain the path to the point. The string can also contain parameters that specify the value that the data reference returns. If specified in an attribute template, the string can contain parameters that specify the point to create. In the string, you separate the parameters with semi-colons.

Examples

• Simple reference to a point on a Data Archive server called MyPIDataArchiveServer:

  \\MyPIDataArchiveServer\sinusoid

• Configuration string referencing the same point, but with a time retrieval specification and specified units of measure:

  \\MyPIDataArchiveServer\sinusoid;TimeMethod=ExactTime;UOM=°C

• Configuration string referencing the same point, but returning a total of point values over a time range:

  \\MyPIDataArchiveServer\sinusoid;TimeMethod=NotSupported; TimeRangeMethod=Total;RateConversion=day

• Configuration string from an attribute template, using substitution parameters:

  \\%Server%\%Element%.%Attribute%

• Same configuration string, but with tag creation enabled and point configuration specified:

  \\%Server%\%Element%.%Attribute%;ptclassname=classic;pointtype=Float32; engunits=m3/s;location1=1;location2=30;location4=1;location5=1;pointsource=R
