GLOSSARY OF TERMS
Address A location in memory where data or programs are stored. It can also identify a
location of a node on a network.
Application A software program that accomplishes a specific task. Examples of applications are
CX-Programmer, CX-Server, CX-Protocol and Microsoft Excel.
ASCII American Standard Code for Information Interchange.
BCD Binary Coded Decimal.
Binary Coded Decimal A data format supported by CX-Programmer: each group of four bits in the data is a
representation of a digit (0-9).
Binary A data format supported by CX-Programmer. A number system format to the base 2,
i.e. employing the digits 0 and 1.
Bit A digit used in binary notation, which can take the value 0 or 1. The value of a bit, or
combination of bits, can represent the status of a device or can be used in
programming.
Boolean A type of point or symbol where the value can be one of two states. Essentially the
two states are ‘0’ and ‘1’, but these states can be assigned a meaningful designation.
Central Processing Unit The part of the PLC that can store programs and data, execute the instructions in
program, and process input and output signals in order to communicate with other,
external, devices.
Clipboard An area within the windows environment where data can be stored temporarily or
transferred between applications.
Components The CX-Server application, as utilized by CX-Programmer, is made up of six
components accessible from an invoking application.
CPU type The type of CPU available to a specific device, the amount of memory available to a
PLC varies according to the CPU involved.
CPU Central Processing Unit.
CS/CJ/CP-series Indicates any one of the following types of PLC: CS1G, CS1G-H, CS1H, CS1H-H,
CJ1G, CJ1G-H, CJ1H-H, CJ1M, CP1H, CP1E.
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*, CPM2*-S*.
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 CX-Programmer.
CX-Net Network Configuration tool
A of a suite of programs allowing the management of Routing Tables and Data Link
Tables in OMRON PLCs.
CX-Programmer A PLC programming application for the creation, testing and maintenance of
programs associated with the OMRON CS/CJ/CP-series PLCs, CV-series PLCs and
C-series PLCs. It provides facilities for the support of PLC device and address
information and for communications with OMRON PLCs and their associated
network types.
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.
Data area An area of PLC memory allocated to the storage of data (not programs).
Data Trace/Time Chart Monitor component
The CX-Server application, as utilized by CX-Programmer, displays data obtained
from the PLC’s memory areas during program execution.
