M M M M
manual call point manual call point manual call point manual call point
A component of a fire detection and fire
alarm system which is used for the manual
initiation of an alarm.
Modbus Modbus Modbus Modbus
An industry standard communications
protocol developed by Modicon. Used to
communicate with external devices such as
distributed control systems or operator
interfaces.
Modbus object Modbus object Modbus object Modbus object
A representation of the configuration
settings for a Modbus master or for its
associated slave links, within the AADvance
Workbench. The settings include
communication settings and messages.
module locking screw module locking screw module locking screw module locking screw
The AADvance latch mechanism seen on
the front panel of each module and
operated by a broad, flat-blade screwdriver.
Uses a cam action to lock to the processor
base unit or I/O base unit.

NFPA 85 NFPA 85 NFPA 85 NFPA 85
The Boiler and Combustion Systems
Hazards Code. Applies to certain boilers,
stokers, fuel systems, and steam generators.
The purpose of this code is to contribute to
operating safety and to prevent uncontrolled
fires, explosions and implosions.
NFPA 86 NFPA 86 NFPA 86 NFPA 86
A standard for Ovens and Furnaces.
Provides the requirements for the
prevention of fire and explosion hazards in
associated with heat processing of materials
in ovens, furnaces and related equipment.

The state of a controller that is executing
the application software.
OPC OPC OPC OPC
A series of standards specifications which
support open connectivity in industrial
automation.
output (Workbench variable) output (Workbench variable) output (Workbench variable) output (Workbench variable)
In the context of an AADvance Workbench
variable, this term describes a quantity
passed from the Workbench to a controller.
P P P P
peer to peer peer to peer peer to peer peer to peer
A Peer to Peer network consists of one or
more Ethernet networks connecting
together a series of AAdvance and/or
Trusted controllers to enable application
data to be passed between them.
pinging pinging pinging pinging
In Modbus communications, sending the
diagnostic Query Data command over a link
and by receiving a reply ensuring that the
link is healthy and the controller is able to
communicate with the master. No process
data is transferred or modified. In the case
of slave devices that will not support pinging
then the Standby command will default to
Inactive state, but no error will be returned.
portable equipment portable equipment portable equipment portable equipment
Enclosed equipment that is moved while in
operation or which can easily be moved
from one place to another while connected
to the supply. Examples are programming
and debugging tools and test equipment.
process safety time (PST) process safety time (PST) process safety time (PST) process safety time (PST)
For equipment under control this
represents the period of time a dangerous
condition can exist without the protection
of a safety instrumented system before a
hazardous event occurs.
processor base unit processor base unit processor base unit processor base unit
A backplane assembly which holds all of the
processor modules in an AADvance
controller. Part number 9100. See also
'processor module'.
