logic states, the application program, and clock settings. Block: See Genius Block and Genius . Bus: See Genius Bus. Bus Controller: See Genius Bus Controller. Bus Group: A group of two or three Genius Bus Controllers, and their busses which have GMR-configured blocks attached. C “C” Block: An application Program Block written in the “C” programming language. Channel: When applied to analog signals, a channel consists of the single input signal or output signal electrical conversion, either analog-to-digital or digital-to-analog. Checksum: A mathematical computation done on a range of bits from a set parallel pattern, performed to see whether the data has changed. This is done in the GMR CPU to verify that the program logic has not been altered. It is dynamically checked. CIMPLICITY: A family of operator MMI (Man-Machine Interface) products ranging from small single stations to large multi-station systems. CMF: Common Mode Failure. See Common Cause Cold Start: When one or more CPUs are initiated, if they are the only CPUs in a system (that is, no other CPUs are currently present), the startup sequence for diagnostic and error detection goes from offline to operational for all activated components. Configuration: The process of defining the hardware architecture and system component settings such as communication parameters, diagnostic limits, and variable scaling. Configuration Software The portion of the Logicmaster 90 programming software used to configure the and many system parameters. Common Cause: failures, faults; An unreliable or error-based signal from one part of the system that causes the whole system to become inoperable or unstable. No Common Mode of Failure (CMF) is considered acceptable. Covert Fault: A hidden, latent, or undetected fault that may affect overall system availability and reliability. Diagnostic detection of covert faults increases reliability and availability and reduces MTTR. CPU Sweep: The process by which the CPU repeatedly executes the application program, updates the status, handles communications and other tasks, and performs internal diagnostics. GFT-177A Appendix D GMR System Glossary D-3 D CPU (Central Processing Unit) The master module in the main PLC system rack which executes the application program. D Data Communications: The ability to electronically transfer system data between the CPU and other intelligent master and slave devices. Data Memory: Areas of memory that are used by the application program to store data. Datagram: A message sent from one Genius device to another. The message length can be up to 128 8-bit bytes. De-energize–to–Trip: Most elements in a GMR system are engineered to be energized operational. For such elements, the safe state is to be de-energized upon a signal or voted signal. Degradation Path: The method used to keep an area of a fault-tolerant system operational when some part of it is lost. Detected Failure: An apparent (not covert) failure. The failure is detectable because it causes a change of operation request. For a control or ESD system, this is the safe state. Diagnostic Coverage: The extent to which a system is able to diagnose improper operation and failed system components. Diagnostics: Active mechanisms that can detect both covert and apparent faults. Discrepancy: Disagreement among corresponding votes in a votoing system. Discrepancy Filter: A selectable time delay that may be applied to corresponding elements in a voted group in real-time transitional systems. The delay allows system asynchronicity at the field device, scan, and logic execution level.
