7. Switch back to the Point Editor and select Paste.
If the pasted point names already exist, CX-Supervisor will automatically add
or increment a number on the end to prevent overwriting. If you wish to
overwrite to replace old point settings, simple delete (not Cut) the old points
from the Point Editor before pasting.
All pasted points will pasted into the group on view
It is possible to reconfigure points at runtime via the right mouse button
floating menu option Points Maintenance. The Point Maintenance dialog box
opens.
To monitor and change the value of a point in runtime, select a point from the
Point Name: field. The Filter Options: field and settings refines the points listed
in the Point Name: field. Select the Get Value button to retrieve the current
value of the selected point. Specify a new point value in the Point Value/Text:
field and click the Set Value button. The Diagnostics button shows details
including communications statistics, useful for diagnosing communication
problems. Note this button is only available when a user with 'Designer'
privileges is logged in. Select the Close button to complete the operation.
PLC communication speeds can be increased by creating "array" points which
contain several elements of the same type, rather than creating a large
number of individual points. For instance, the time taken to update an array
point containing 50 elements are quicker than the time taken to update 50
individual points.
An "array" point can be created by specifying a value greater than 1 in the
Elements: field of the Setup PLC Connection dialog box. The Data Location
field specifies the memory address from which the array of data begins.
Note:Elements of an array point are located at consecutive addresses after
the address specified in the Data Location field.
Accessing Elements of an "Array" Point
Direct access to array points can be achieved by applying a subscript to the
pointname, e.g. pointname[index]. For more information refer to the CX-
Supervisor Script Language Reference Manual.
