Remarks
Argument Type
Description
returnstate
bool
Returnstate
is ‘1’ if the function is successful, or ‘0’ otherwise.
graphid
string
The identifier of the trend graph to have a snapshot
pagename
string
Optional
parameter indicating the name of the page that the
graph is on.
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 Type
Description
pointname
point
This is the name of the point whose contents are to be returned.
offset
integer
This specifies the offset into an array point. 0 if the point is not
an array point.
returnpoint
point
Point that contains the return value. The type of data returned is
dependant on the pointname specified.
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].
