Remarks
Argument
returnstate
graphid
pagename
Typical Examples
Snapshot("Graph_1", "TestPage1")
The current data in trend graph 'Graph1' on 'TestPage1', is stored and is able to be viewed via the
EditGraph command.
Snapshot("Graph_2")
The current data in trend graph 'Graph1' on the current page, is stored and is able to be viewed via
the EditGraph command.
Note: This command is provided for compatibility with SCS v2.0 applications. For newer
applications the data logging facilities should be used in preference.
GetPointValue
Syntax
returnpoint = GetPointValue(pointname,offset)
Remarks
Argument
pointname
offset
returnpoint
Typical Example
pointname = 10;
returnpoint = GetPointValue(pointname,0)
The point 'returnpoint' contains the value 10. The offset is added to any offset specified for
pointname. For example:
returnpoint = GetPointValue(a[10],10)
Causes the 21st element (offsets begin at zero) of array 'a' to be retrieved.
Note: It is often simpler to access an array element directly, e.g. returnpoint = a[20].
