CIP Common Industrial Protocol. A communications protocol created by
Rockwell Automation for the Logix controller family, and supported by the
AADvance controller. AADvance controllers use the protocol to send data to
and from Logix controllers using a consumer/producer model. It can also be
used to communicate data between AADvance controllers.
clearance The shortest distance in air between two conductive parts.
coding peg A polarizing key, fitted to the 9100 processor base unit and to each termination
assembly ensuring that only a module having the correct type can be fitted in a
slot. Part number 9903.
coil In IEC 61131-3, a graphical component of a Ladder Diagram program
representing the assignment of an output variable. In MODBUS language, a
discrete output value.
Compiler Verification Tool (CVT) A software utility that validating a compiled application to look for errors
introduced by the Workbench or the compiler. Frequently abbreviated to
CVT.
configuration A grouping of the application software and settings for a specified 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 representing 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 condition.
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 are detected by automated diagnostics. See also
'SFF'.
creepage distance The shortest distance along the surface of an insulating material between two
conductive parts.
cross reference Information calculated by the AADvance Workbench relating to the
dictionary of variables and where those variables are used in a project.
