Performance Equations (Core Services)

Expression variables are references to attributes or points using relative syntax to the target, which is typically a database, element or a Data Server. Variables must be enclosed in single quotes. Calculations are limited to attributes or points which originate from a single server. Attributes which resolve to a static value (no data reference configured), are also acceptable. Examples of valid target and expressions:

Target	Example Expression
none	'\\myPIServer\sinusoid'*2
none	'\\myAFServer\myDB\myElement|myAttribute'*2
Data Server	'sinusoid'*2
Asset Server	'myRootElement\myChildElement|myAttribute'*2
element	'myAttribute'*2
element	'myAttribute|myChildAttribute'*2
element	'.\myChildElement|myAttribute'*2
element	'\\myPIServer\sinusoid'*2
event frame	'myAttribute'*2
attribute	'.'*2
attribute	'myChildAttribute'*2
attribute	'..|mySiblingAttribute'*2

Note that some characters used in Performance Equations, such as ''' and '+', must be URL-encoded.
