blanking cover
A plastic moulding to hide an unused slot in
an AADvance base unit.
boolean
A type of variable that can accept only the
values 'true' and 'false'.
BPCS
Basic process control system. A system
which responds to input signals and
generates output signals causing a process
and associated equipment to operate in a
desired manner, but which does not
perform any safety instrumented functions
with a claimed safety integrity level of 1 or
higher.
Refer to IEC 61511 or to ANSI/ISA—
84.00.01—2004 Part 1 (IEC 61511-1 Mod)
for a formal definition.
Equivalent to the Process Control System
(PCS) defined by IEC 61508.
breakdown voltage
The maximum voltage (AC or DC) that can
be continuously applied between isolated
circuits without a breakdown occurring.
BS EN 54
A standard for fire detection and fire alarm
systems.
BS EN 60204
A standard for the electrical equipment of
machines, which promotes the safety of
persons and property, consistency of
control response and ease of maintenance.
bus
A group of conductors which carry related
data. Typically allocated to address, data and
control functions in a microprocessor-based
system.
bus arbitration
A mechanism for deciding which device has
control of a bus.
C
CIP
Common Industrial Protocol. A
communications protocol, formally known
as 'CIP over Ethernet/IP', created by
Rockwell Automation for the Logix
controller family, and which is also
supported by the AADvance controller.
AADvance controllers use the protocol to
exchange data with Logix controllers. The
data exchange uses a consumer/producer
model.
clearance
The shortest distance in air between two
conductive parts.
coding peg
A polarization key, fitted to the 9100
processor base unit and to each termination
assembly, which ensures only a module of
the correct type may be fitted in a particular
slot. Part number 9903.
coil
In IEC 61131-3, a graphical component of a
Ladder Diagram program, which represents
the assignment of an output variable. In
Modbus language, a discrete output value.
Compiler Verification Tool (CVT)
The Compiler Verification Tool (CVT) is an
automatic software utility that validates the
output of the application compilation
process. This process, in conjunction with
the validated execution code produced by
the AADvance Workbench, ensures a high
degree of confidence that there are no
errors introduced by the Workbench or the
compiler during the compilation of the
application.
configuration
A grouping of all the application software
and settings for a particular AADvance
controller. The grouping must have a
'target', but for an AADvance controller it
can have only one 'resource'.
