The tables are retentive until reset or cleared. Fault Tolerance: If a single element fails, the ability of a system to remain functional as if no fault had occurred. The diagnostics will report the fault to the proper fault table. Final Control Element: The actuator, indicator, or other electrical field device controlled by an output point. Firmware: A series of instructions contained in ROM (Read Only Memory) of a CPU which are used for internal processing functions. These instructions provide the structure for application program operations. GFT-177A Appendix D GMR System Glossary D-5 D Forcing : Deliberately changing an point value, regardless of the actual input value or commanded output value. The Genius Hand-held Monitor (HHM) can be configured to perform forcing. The PLC’s Fault Table indicates both forces and released forces. G Genius Bus: The LAN (local area network) used for Genius communications. Genius bus protocol is an enhanced type of IEEE 802.4 token-passing scheme. Each transmission is voted 2oo3 by the receiving device to assure data integrity. The bus operates at up to 153.6Kb without special connectors or amplifiers. A single Genius LAN supports up to 32 devices, and up to 31 LANs may be included in one Series 90-70 PLC. The bus uses twisted pair cable. It may be multidrop-wired up to 7500’. Longer busses are possible using fiber optic cable and modems. Genius Bus Controller: The PLC module that interfaces the GMR Series 90-70 PLC with a Genius bus, acting as the master communications module. blocks in a system communicate with the Bus Controller over the Genius bus. Genius : An family of intelligent distributed products including many types of Genius blocks, Genius Bus Controllers, and other devices. Genius Block: An electrical signal interface module capable of reporting inputs and controlling outputs for both digital and analog devices. A Genius block converts signals from user devices to/from the logic levels used by the CPU. Each block is self-contained, with a built-in communications processor, block power supply, and control. Genius blocks may be mounted locally or remotely, and are rated for use in hazardous locations. Extensive block diagnostics report failures, even in the device system, back to the Bus Controller. Genius LAN: See Genius Bus. Global Data: Data that is broadcast on the Genius LAN each bus scan. Global Data may be received by any intelligent connected device. GMR: An acronym for Genius Modular Redundancy. GMR is a triple modular redundant (TMR) and flexible high integrity system. It has scaleable configuration for: n single, dual, or triple input support, n single, dual, or triple CPU support, n fail safe, fault tolerant, and fault tolerant/fail safe output support. H “H” Pattern Output: A fault-tolerant output whose state is controlled by two parallel sink Genius blocks and two parallel source Genius blocks. Hot Backup: A redundant component ready to and capable of coming online without causing a “bump” in the process. Typically this requires synchronization and online supervisory diagnostics. D-6 Genius® Modular Redundancy Flexible Triple Modular Redundant (TMR) GFT-177A System Technical Product Overview – February 1998 D Hot Standby: A redundant device ready to be manually or automatically placed online. Hot Standby devices help shorten the MTTR cycle. I “I” Fault Tolerant for Control Operational: A Fault Tolerant circuit when used in safety circuits that are normally de-energized to “safe”. See Fault Tolerant.. Fault Table: A diagnostic table in the Series 90-70 PLC that lists faults.
