OMRON GLOSSARY OF TERMS – CX-Server Runtime
Revision 2.0 CX-Server Runtime_Page 91
Rotary switch Indicates the method of calling a device by generating a series of pulses.
Routing table A table containing the information necessary to allow communications between
different networks including local and gateway network address details.
Routing The direction of data across a network from its source to its destination.
RS232 Industrial interface standard for serial communications.
RS422 Industrial interface standard for serial communications employing balanced line
circuits.
Serial Connection A direct connection between computer and PLC.
Server 1. Server is used in DDE functions to contain a link to an outside application. Using
DDE functions, CX-Server allows the manipulation of an outside application as
specified as the Server.
Refer also to Server application.
2. A Server is the central processing point of a Network which is accessible to all
computers. Networks affect CX-Server in that further associated options are
available if the computer Network is connected.
Slots Free areas within a rack to which units can be fixed.
Stop bits Bits indicating the end of transmission of each set of data bits; normally one or two
bits, they indicate the delay time between sending successive characters down the
line.
Symbol An address that has been given a name to make the address information more
flexible. Symbols are inherited by CX-Server by the invoking application.
SYSMAC LINK OMRON high speed industrial network (either co-axial or fibre optic).
SYSMAC NET OMRON high speed optical LAN which can be of type C SYSMAC NET or CV
SYSMAC NET.
SYSMAC WAY OMRON network.
System area An area of memory used for controlling and managing a unit.
System configuration An arrangement of units, for example network, computers and PLCs.
Tagged database A file format supported by the CX-Server Import tool. The Tagged database is also an
export format of the CX-Server Import tool.
Target PLC The PLC to which information or instructions are directed.
Taskbar An integral part of Microsoft Windows which allows Microsoft Windows based
applications to be started. CX-Server tools are run from the Taskbar.
TCP/IP Transmission Control Protocol/Internet Protocol.
Temperature Controller An OMRON device.
Temporary Relay Area An area of PLC memory containing instructions which can be loaded at a later point
for use with other instructions.
Text 1. A file format supported by the CX-Server Import tool. The Text is also an export
format of the CX-Server Import tool.
2. A data format supported by CX-Server.
Timer area An area of PLC memory containing program timers and their related completion
flags.
Toolbus A network, either C-Toolbus or CV-Toolbus, allowing communications with a device
via the serial COM port of a personal computer (in a similar manner to SYSMAC
WAY). Data is transmitted along the network in binary format.
Tools CX-Server is made up of four tools.
Transfer from PLC The transfer of a program or data to a host (either a computer or a programming
device) from a lower-level (or slave) device.
Transfer to PLC The transfer of a program or data from a host (either a computer or a programming
device) to a lower-level (or slave) device.
UDP User Datagram Protocol.
Unit number A number identifying an individual component of an OMRON PLC system
configuration.
Units A component of an OMRON PLC system configuration.
