Memory Card component The CX-Server application, as utilized by CX-Programmer, manages the file storage
to and from PLC memory cards.
Microsoft Excel A spreadsheet application.
Microsoft Windows Explorer A file handling application part of the Microsoft Windows suite.
Microsoft Windows A windowing environment that is noted for its GUI, and for features such as multiple
typefaces, desk accessories (such as a clock, calculator, calendar and notepad), and
the capability of moving text and graphics from one application to another via a
clipboard.
CX-Programmer runs only under Microsoft Windows. DDE functions communicating
with other applications supported by CX-Programmer use Microsoft Windows as a
basis.
Monitor mode A PLC operational mode that allows the device, during normal execution, to review
the condition of the Data Link (including the PLCs/nodes on that link).
Network 1. Part of the PLC configuration, based on the device type. The number of Networks
available is dependant on the device type.
2. A number of computers linked together with a central processing point known as a
server that is accessible to all computers. Networks affect CX-Programmer in that
further Network associated options are available if the computer is Network
connected.
Offline The status of a device when it is not being controlled by a computer (although it may
be physically connected to it).
OLE Object Linking and Embedding. Used to transfer and share information between
Microsoft Windows based applications and accessories.
Online The status of a device when it is under the direct control of a computer.
Output The signal sent from a PLC to an external device.
Output instruction A type of PLC instruction that appears at the right of a ladder rung – it cannot be
connected to at the right.
Output window An area of the CX-Programmer display reserved for compilation messages and search

PLC Error component The CX-Server application, as utilized by CX-Programmer, displays and manages
PLC errors.
PLC Memory component The CX-Server application, as utilized by CX-Programmer, allows the user to view,

is separate and is similar in concept to a document.
project workspace An area of the CX-Programmer reserved for displaying and selecting project content.
Rack The apparatus to which a unit is fixed.
RAM Random Access Memory.
Reset Turning a bit or signal OFF or changing it to its set value or to zero.
Run Mode PLC mode of operation during which device information is typically read-only.
Rung A logical circuit of a ladder program (a connection from the left to the right bus-bars).
A rung can encompass one or more columns and rows.
Section A part of a PLC program, like a chapter is to a book. The sections are combined in
