Glossary
The following terms are used in this manual to describe the function blocks of the G9SP-series Safety
Controllers.
Terminology
Term Definition
Safety Describes a device, function, data, or other element for which special safety measures
have been implemented for use in Safety Controls.
Standard Describes a device, function, data, or other element that is used in Standard Controls.
Used to differentiate from devices, functions, data, or other elements for which special
safety measures have been implemented for use in Safety Controls.
Safety Controller A highly reliable controller that is used in Safety Controls.
Standard PLC A programmable controller (PLC) that is used for general controls.
Used to differentiate from a PLC used for Safety Controls.
Expansion I/O Unit The name of the CP1W-20EDT(-1) and CP1W-32ET(-1).
Some of the OMRON CP1-series Expansion I/O Units can be used in a G9SP-series
Controller. Expansion I/O Units are connected to a G9SP-series Controller to increase
the number of Standard I/O points.
Option Board The name of the CP1W-CIF01 and CP1W-CIF41.
Some of the OMRON CP1-series Option Boards can be used in a G9SP-series Control-
ler. An Option Board can be mounted in a G9SP-series Controller to communicate with a
Standard PLC.
Memory Cassette The name of the CP1W-ME05M.
This OMRON CP1@-series Memory Cassette can be used in a G9SP-series Controller. It
is used to back up and restore configuration data in G9SP-series Controllers.
G9SP Configurator The name of the WS02-G9SP@@.
Support Software that is used to set up, program, and debug G9SP-series Controllers.
configuration data Setup data that is used to operate a G9SP-series Controller. The configuration data is
created with the G9SP Configurator and then downloaded from the computer to memory
in the G9SP-series Controller. The configuration data contains the unit configuration set-
tings, I/O terminal settings, system settings, and Safety Program.
backup An operation used to write the configuration data stored in internal memory in the G9SP-
series Controller to a Memory Cassette.
restore An operation used to write the configuration data stored in a Memory Cassette to internal
memory in the G9SP-series Controller.
Safety Input Device An input device for which special safety measures have been implemented for use in
Safety Controls. Safety Input Device is therefore a generic term for input devices such as
emergency stop switches and safety door switches.
Safety Output Device An output device for which special safety measures have been implemented for use in
Safety Controls. Safety Output Device is therefore a generic term for output devices such
as safety relays.
CP Series A series of programmable controllers manufactured by OMRON.
NE1A Series A series of Safety Network Controllers manufactured by OMRON. NE1A-series Control-
lers are high-end controllers in comparison to the G9SP-series Controllers.
dual channels Two channels that are used for redundancy with Safety Inputs or Safety Outputs. If the
two channels must have the same value, they are called equivalent dual channels. If they
must have the opposite values, they are called complementary dual channels.
discrepancy The state in which the status of two dual channels do not agree, resulting in a discrep-
ancy error.
