Mechanical keying prevents modules from being inserted into the wrong location. The architecture of a GMR system makes it possible to replace any module while the system continues operating. a46600 Power Supply 123 456 789 POWER SUPPLY PROGRAMMABLE CONTROLLER CENTRAL PROCESSOR UNIT GENIUS BUS CONTROLLER GENIUS BUS CONTROLLER GENIUS BUS CONTROLLER BUS TRANSMITTER GE Fanuc SERIES 90-70 PROGRAMMABLE COPROCESSOR COMMUNICATIONS COPROCESSOR ETHERNET CONTROLLER Series 90-70 PLC 19-inch Main Rack with Typical Modules Modules can be selected to suit the application 3-2 Genius® Modular Redundancy Flexible Triple Modular Redundant (TMR) System GFT-177A Technical Product Overview – February 1998 3 PLC Redundancy Options Redundancy options for the PLC portion of a GMR system include: Simplex: one PLC Duplex: two PLCs Triplex: three PLCs Each PLC CPU resides in an independent rack, eliminating mechanical and electrical common mode failure. Individual PLC CPU racks may be located up to 7500’ apart (the maximum distance between PLCs depends on the baud rate selected for the Genius bus that connects them). A minimum of two bus controllers per PLC are required for fault-tolerant inter-processor communications. This allows the GMR PLCs to exchange initialization data at startup and exchange up to 64 words of global data during operation. For maximum system integrity, two or three PLCs protect against failure of the PLC CPU or power source, or even loss of an entire PLC system. The ability to have processing performed by two or three independent PLCs is an additional important advantage of GMR. Even when only one PLC is used, triplicated Genius Bus Controllers and bus cables, along with the ability to have triplicated inputs and fault tolerant, failsafe voted outputs, provides significant levels of redundancy. The GMR redundancy options for both inputs and outputs can be used with one, two, or three GMR PLCs, as shown by the following illustrations. For clarity, the illustrations show PLCs without expansion racks and only a few Genius blocks per bus. In an actual system, there can be up to eight racks per PLC and 32 devices (Genius blocks, Bus Controllers, etc) per Genius bus.

The use of duplex or triplex sensors that provide signals to either two or three Genius blocks or Field Control analog input modules from the same portion of the monitored process provides maximum input redundancy. Redundancy options for input devices in a GMR system are shown in the following illustrations. The types of redundant input options shown in these illustrations are available for both discrete inputs and analog inputs. Note that analog inputs can use either Genius or Field Control devices, including inputs from thermocouples and RTDs.
