Editing CX-Server Project
Points and groups within a CX-Server project can be edited via the CX-Server Project Editor which is accessed
from the Import/Export tool or the DDE Manager. The Project Editor allows new points, groups and devices to
be added, modified to and/or deleted from the CX-Server project.
A CX-Server Project can be edited by selecting Edit from the Project option on the menu bar of the Import /
Export tool or by opening / editing a project in the DDE Manager. The option is not available to all tools and
components and is further unavailable unless a CX-Server project has been opened or created.
Click on the Points Setup pushbutton in the edit project dialog to edit the CX-Server project. The information
displayed includes the following:
A ‘devices’ view showing all devices configured in the CX-Server project and each device
available memory areas. The complete group hierarchy of the CX-Server project, and details
of the points (in their memory areas) within the CX-Server project.
A ‘points’ view showing details of the points (within their groups).
Comments (name and address comments) relating to a point are displayed when the appropriate element is
highlighted.
A point represents an input or output data area within a PLC; it can refer to a single bit of data (representing for
example, “Hopper empty”, “Activate Reject Solenoid”), or to a multiple bit word (representing for example,
“Process Temperature”).
Associated with each point is a name and address indicating its position within a PLC and a PLCs memory;
comments can also be entered against a point’s name and address.
The information held at a point can be read or updated by CX-Server. A third party can also access this point
data by establishing a link between that and the PLC.
Note: More than one point can have the same address, any comment entered against this
address applies to all points at this location. Comments entered against the point name
are unique to that point only. Points do not have to have a name, however, if a name is
supplied it must be unique.
To access the Project Editor, open the CX-Server Import/Export tool and open or create a project. Then from the
Project menu select Edit, this opens the Edit Project dialog. In Edit Project click the Points: Setup button.
