Glossary
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'.
consumer
The consuming controller requests the tag from the producing controller.
contact
A graphical component of a Ladder Diagram program, which represents the
status of an input variable.
continuous mode
Where the Safety Instrumented Function in the Safety System is continually
maintaining the process in a safe state.
controller
A logic solver; the combination of application execution engine and I/O
hardware.
controller system
One or more controllers, their power sources, communications networks and
workstations.
coverage
The percentage of faults that will be detected by automated diagnostics. See
also 'SFF'.
creepage distance
The shortest distance along the surface of an insulating material between two
conductive parts.
