CX-Server PLC Tools Page 172
C-Series Indicates any one of the following types of PLC: C2000H, C200H, C200HE,
C200HE-Z, C200HG, C200HE-Z, C200HS, C200HX, C200HX-Z, C1000H, C**H,
C**K, C**P, CQM1, C500, C120, C20, CPM1 (CPM1A/CPM2*).
CV-Series Indicates any one of the following types of PLC: CVM1, CVM1-V2, CV500, CV1000
or CV2000. When using SYSMAC NET, CV series PLCs can operate in either CV
mode (where the datagrams contain FINS commands) or C mode (where the datagrams
contain C SYSNET commands).
CVSS A file format supported by the CX-Server Import tool. CVSS has several file types
which have different information contained in them.
CX-Net Network Configuration tool
This CX-Server tool consists of a suite of programs allowing the management of
Routing Tables and Data Link Tables in OMRON PLCs.
CX-Server An advanced communications management system for OMRON PLCs providing
facilities for software to maintain PLC device and address information and to
communicate with OMRON PLCs and their supported network types.
CX-Server Project A definition of an OMRON PLC network configuration. It identifies all devices and
networks within a particular configuration including the areas of PLC memory (points)
that can be read from or written to.
Cycle time The time interval between read/write cycles at a network node.
Data area An area of PLC memory allocated to the storage of data (not programs).
Data bits Bits representing each character to be transmitted.
Data link A software connection establishing common data areas between PLCs on a network
allowing data to be between these devices.
Data Link Editor The data Link Editor allows a PLC to be configured so that it can participate in one, or
more automatic data sharing schemes, over Sysmac Link and Controller Link networks,
without the need for special programming.
Data link table A table of the common data memory areas used by the PLCs in a Data Link.
Data location An area of memory identified by an address.
Data memory An area of PLC memory holding only word data.
Data Trace/Time Chart Monitor component
This CX-Server component displays data obtained from the PLC’s memory areas
during program execution.
Datagram A packet of information which can be transmitted across a network containing routing
information plus data.
DDE Dynamic Data Exchange. A channel through which correctly prepared programs can
actively exchange data and control other applications within Microsoft Windows.
CX-Server, through the use of the DDE Manager tool, allows extensive use of DDE
functionality.
See also Item, Server, server application and Topic.
DDE management library A dynamic link library within Windows which allows dynamic data exchange to be
employed.
DDE Manager tool A CX-Server tool for transferring data between PLCs and a client application using
DDE, for example Microsoft Excel.
DDEML Dynamic Data Exchange Management Library.
Debug mode A mode of PLC operation during which any errors arising from the currently active
program will be flagged. For CV-series PLC only.
Decimal A data format supported by CX-Server.
Default A value automatically set by a program in the absence of user input or on initial entry to
an application; such values can be overwritten.
Destination network address The address of the network to which data is directed.
Destination node number The number identifying the destination node.
