PC reach the end connection PLC, the gateway PLC must contain the routing information which identifies this
PLC. Procedures for configuration of the network is provided in the
Chapter 8 CX-Server Network
Configuration Tool , Chapter 10 Data Links , Chapter 11 Routing Tables in the PLC Tools User Manual .
Connection to the PLC requires the specification of the type of communications interface to be used to connect
to the PLC. CX-Server supports two methods of communication: serial communications and network
communications. Serial and network communications can be made using the Connection Type dialog although
these are dependent upon the type of PLC being communicated with.
Points
The CX-Server project file also contains a list of addresses which may be accessed in the defined PLCs, each
address being contained inside a
point . Each point has the following attributes:
♦ Name . A unique label within its group so that the point can be easily referenced, similar to folders in
Microsoft Windows Explorer (for example, ‘Conveyor Position’).
♦
Comment . A free-form long comment used only for reference by the user.
♦
Address . The location of the information inside the configured PLC:
♦
including the PLC (by name, matching the label of the defined PLC),
♦
address (for example, ‘D0’),
♦
the number of elements (for example, ten elements for ten channels) and type (for example, bit,
channel, floating point).
Points are stored within the CX-Server project file in a hierarchical group structure. New groups may be added
to the CX-Server project at any level of the hierarchy tree. Groups act as container objects (as folders contain
files) for relevant points within a CX-Server project. Similar points may be banded together and stored within
these groups.
Editing a CX-Server Project PLC List
The Edit Project dialog allows the PLC or Points information in the currently opened CX-Server project to be
modified, deleted or added. A CX-Server Project PLC list can be edited from either the Import/Export tool or
the CX-Net tool by selecting the appropriate .cdm file and then selecting Edit from the Project menu.
Alternatively from the Project Editor right click on Devices and select the Properties option or select Properties
from the File menu.
Alternatively from the Project Editor right click on Devices and select the Properties option or select Properties
from the File menu.
Click on the PLCs Setup pushbutton in the edit project dialog to edit the CX-Server project PLC list.
The Device List dialog is subsequently displayed; this is the central point for adding and setting up PLCs and
lists all currently defined PLCs in the open CX-Server project file, their type, network details and any comments
associated with each device.
