The real hardware configuration of the PLC units and slots on power-up.
A location in memory where data or programs are stored. It can also identify a location
of a node on a network.
A software program that accomplishes a specific task. Examples of applications are
CX-Server, CX-Programmer, CX-Protocol and Microsoft Excel.
American Standard Code for Information Interchange.
An area of PLC memory which normally contains transmission Counters, flags and
control bits. It also retains the status of the device during power failure.
The speed of data transmission in terms of the number of bits per second that are being
sent.
Binary Coded Decimal.
A data format supported by CX-Server.
A data format supported by CX-Server. A number system format to the base 2, i.e.
employing the digits 0 and 1.
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.
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.
A device connecting local area networks of similar architectures together.
An address held in common by all nodes on a network to which the same data is
transmitted simultaneously.
A communications path along which data can be transmitted or received between the
units connected to it.
The part of the PLC which can store programs and data, execute the instructions in
program, and process input and output signals in order to communicate with other,
external, devices.
An area within the windows environment where data can be stored temporarily or
transferred between applications.
An optional part of an address string indicating the modification to be performed on the
data at that address (within PLC memory) when it is accessed.
The common words used by all PLCs in a Data Link (within a SYSMAC LINK
system).
A type of memory card fitted to a PLC.
CX-Server is made up of six components accessible from an invoking application.
A bit assigned a controlling role in the functioning of a device; its status is set via a
program to achieve this function.
A network that can send and receive large data packets flexibly and easily among the
OMRON PLCs.
An area of PLC memory containing program counters and their related completion
flags.
An area of memory reserved for the purposes of counting the number of times an event
has occurred.
An area of PLC memory allocated to the CPU bus unit.
The type of CPU available to a specific device, the amount of memory available to a
PLC varies according to the CPU involved.
Central Processing Unit.
Indicates either a CS1G-H, CS1H-H, CS1D-S, or CS1D-H.
Indicates either a CJ1G-H, CJ1H-H, or CJ1M.
