GE Intelligent Platforms have for many years provided high integrity safety system solutions to a wide spectrum of industries including: Oil & Gas Exploration and Production, Hydrocarbon Processing, Semiconductor, Transportation and Power Generation. GE Intelligent Platforms has captured this expertise in the GMR integrated system solution.Based upon globally-available hardware, a Genius Modular Redundancy (GMR™) system consists of a number of modular subsystems, integrated to form a flexible and powerful whole. The number and type of subsystems is completely scaleable to the requirements of the application. Utilizing field-proven Series 90™-70 PLC, Genius® I/O, and VersaMax™ I/O products, GMR provides variable redundancy from the input devices through one, two or three PLC CPU processors to the output devices. GMR implements advanced diagnostics throughout the systems to detect overt and covert failures, increasing system uptime, and reducing Mean Time to Repair by pinpointing faults as they occur. In a GMR system, less-critical inputs and outputs may be configured for simplex or duplex operation while maintaining triplicated elements for instrument loops requiring the highest levels of process integrity. The result is a system that provides both base regulatory control and safety system functionality. A key feature of the GMR system is that non-redundant, less critical process control can be configured in the same system as redundant or triplicated safety-critical sections. While a (limited) number of GE Intelligent Platforms PLC products have been TÜV-approved for use in the redundant areas, all GE Intelligent Platforms PLC components can be used in the same system. TÜV has certified GMR to Safety Integrity Levels (SIL) according to ANSI/ISA S84.01, IEC 61508, DIN V19250, DIN/VDE 801 and other international standards relating to the design of Programmable Electronic System (PES) Technologies. The GMR system has received TÜV type approval for use in safety-relevant systems where the safe state is de-energized, such as Emergency Shut Down (ESD) systems, or where the demand state is energized, such as Fire & Gas systems or Boiler Management systems. The flexibility of the GMR system makes it possible to apply the exact mix of redundancy options required by the application. This section describes the architectures that have been certified by TÜV and their expected Safety Integrity Levels (SIL). As described previously, the GMR System can be thought of as consisting of three subsystems, the Input Subsystem, the Processor Subsystem, and the Output Subsystem: In accordance with IEC61508, the highest SIL rating the GMR system can achieve is equal to the lowest SIL rating of these three in-series subsystems. For example, to achieve a SIL 3 control loop, all three GMR subsystems involved in implementing that loop must meet the SIL 3 requirements. The tables that follow list the maximum SIL Rating for different types of GMR input, processor, and output subsystems. (These SIL Ratings correspond directly to DIN Class Ratings; SIL1 = DIN Class 2/3, SIL2 = DIN Class 4, SIL3 = DIN Class 5/6). GE Intelligent Platforms has received TÜV type approval for the GMR system, just as specification specified in this project, for use in safety relevant systems where the safe state is de–energized (e.g. ESD, SIS systems) or the demand state is energized (e.g. Fire & Gas systems, Boiler Management systems). The type approval certificate at the time of printing is 968/EZ 106.00/00. 4.2.1 Sub-System of GMRThe basic parts of a GMR system are the input subsystem, the processor subsystem, and the output subsystem. These subsystems can be designed to provide the exact mix of redundant and non-redundant discrete and analog equipment needed for a broad range of critical control applications.Genius Modular Redundancy provides: · A high degree of self-test and monitoring with diagnostics · Fault tolerance. · Fail safe · Support for centralized or fully distributed systems. · Scalable voting. The proposed system is designed based on following assumption: · Normally-on inputs with normally-energized outputs – Safety System (Shut down Level ¾) · Normally-off inputs with normally-de energized outputs – Safety System (Shut down Level ½) 4.2.2 The Processor Sub-SystemA GMR system normally consists of one to three identical processors running identical application software. Each processor is normally connected to the same input and output subsystems. Each processor receives all inputs and performs voting for discrete inputs and mid-value selection for analog inputs. Each processor computes the required outputs as a function of the inputs and the application program logic. Each processor then sends its own output data to the Genius blocks.Integral to the operation of a GMR system is the GMR software. The GMR software provides both system configuration tools and system software functionality. Added to the program folder for a specific GMR application, the GMR system software controls input voting, special GMR memory mapping, diagnostic messaging, periodic auto-testing, and other operating features of the processor subsystem. Just As following table display, GE Intelligent Platforms proposed systems with dual controller could meet specification requirement for certification (SIL 3) with proper input and output sub-systems. 4.2.3 The Input Sub-SystemThe input subsystem is the part of a GMR system that gathers input data and provides it to the PLCs.The table below lists the maximum SIL rating that can be achieved for each GMR input subsystem configuration. Genius analog input blocks have fewer diagnostics and therefore require more redundancy to achieve the same Safety Integrity Level. According to specification, we assume detector vendor will provide duplex detector for each measure point, in this project GE Intelligent Platforms offered 1oo2 for detectors. Discrete Input Autotest The autotest exercises the system inputs to be sure they remain able to detect and respond to actual inputs. Input Autotest accommodates both normally-closed and normally-open devices with the devices in either state. The test detects input failures that would result in a failure to respond. Discrete Input Autotest does not cause spurious outputs. Operation of the input autotest is internal to each Genius block. After initiation by the Autotest Master PLC, the autotest requires no additional interaction with the PLCs. While it is completing the autotest process, a block continues to supply its last valid set of inputs instead of the physical inputs to the PLCs. The block performs the following actions during an Input Autotest: · Power feed outputs (point 16) are pulsed Off. · Selected input channels are pulsed On · All associated inputs are checked for their ability to detect the On or Off state, as appropriate. A fault is reported if the correct state is not detected. By allowing some inputs to be turned On, the Input Autotest checks for circuit-to-circuit shorts and also checks its own operation. Line Monitoring for 16-Circuit DC Blocks For applications such as Emergency Shutdown (ESD), normally-closed inputs are generally monitored for short circuits across the lines, since that represents a fail to danger condition (that is: trip is not detected). In general, these inputs are powered from +24V, and a field short to ground is interpreted as a trip condition. For applications such as Fire and Gas Detection, normally-open DC inputs are generally monitored for open circuits on the lines, since that represents a fail to danger condition (that is: trip is not detected). In general, these inputs are powered from +24V, and a field short to +24V is interpreted as a trip condition. 4.2.4 The Output Sub-SystemThe output subsystem is the part of a GMR system that provides output data. As customer documents specified and to meet international safety system standards for SIL3/DIN AK6, GE Intelligent Platforms proposed T-Block normally de-energized output for safety system shutdown level 1/2 (Simplex actuator) and I-Block normally energized output for safety system shutdown level 3/4 (Simplex actuator).Note: Simplex detector configuration is only permitted under IEC 61508 if the input device conforms with the requirements of IEC 61508 Part 2 Table 2 Architectural Constraints on Type A Safety Related sub-systems and Table 3 Architectural Constraints on Type B Safety Related sub-systems. Discrete Output Discrepancy Reporting Output discrepancy monitoring is the process of monitoring the block’s output voting to detect discrepant output data from the PLC processors. All PLCs periodically monitor all blocks' discrepancy status. On interrogation by any PLC, the block responds with a discrepancy report message indicating any discrepant output and disagreeing PLC. If a PLC is sending discrepant output data to a block, the GMR system logs an output discrepancy fault in the I/O fault table and sets the appropriate fault contacts. The GMR system performs output discrepancy checking whenever it is not performing input or output autotesting (between autotests during the autotest interval). It checks all output blocks in redundant output groups and any nonredundant output blocks marked for discrepancy checking in the GMR configuration. If the GMR system determines that an output changed state during a discrepancy check, it attempts up to three times to properly complete the discrepancy check on an output block. This prevents logging false discrepancy faults that might be caused by the application program changing the state of an output while a discrepancy check is being performed Output discrepancy checking works with outputs that change state less frequently than approximately once per 10 PLC scans. If an output changes state more rapidly than approximately once per 10 PLC scans, the results of output discrepancy checking for that output could be ignored. Nuisance discrepancy faults caused by transitioning outputs should NOT ever be logged. A specific %M command bit (%M12266) can be used to enable/disable fault report information about rapidly-transitioning output discrepancies. Discrete Output Autotest Discrete output autotest checks the ability of outputs to respond to the commanded output state. It detects short circuit, open circuit, failed switch and other types of faults. For discrete output groups, two types of faults may prevent the output autotest from completing for that output group and thus cause an I/O shut down for the outputs in the group. The faults are: · Loss of a block within the group (any failure that causes the block to no longer communicate on the Genius bus such as loss of power.) · Output autotest failure of a type that could potentially prevent a normally energized output from being tripped off. An example is the short of a source block output to +24 Vdc. Output Autotest uses the standard Genius block Pulse Test feature. During testing, the system is online and available. For the test to be performed: · All blocks in the group must be online. · There may be no I/O override applied to any block in the group. · For each block output in the group: · There may be no I/O force applied. · There may be no hardware fault (such as a failed switch). · For all outputs, the corresponding circuit of each block in the group must be in the same logical state. The devices connected to the output circuits to be autotested must be able to withstand the On and Off pulse times discussed in this section. Note that actual times in an application depend on the presence of other scheduled tasks and on the configuration of the points. Pulse testing occurs whether the output is in the On state or the Off state by executing one of two tests. These are the pulse ON-OFF-ON test and the pulse OFF-ON-OFF test. The following Pulse Test descriptions refer to Pulse Test operation of a block configured in the GMR mode only. OFF-ON-OFF Test: The first ON pulse is for about 1.7mS. During this time, if the No Load diagnostic is enabled, the current data is checked and recorded. After this time, the test turns the point Off and the diagnostic, volts, and current data (if No Load is enabled) are checked. If the correct voltage and/or current data is NOT reported, the time constant is increased and the process repeats. If the correct voltage and/or current data is reported after any of the pulses, the test is passed and no further pulsing of the point occurs. The maximum number of pulses that can occur is 7, with a minimum duration of 1.7mS and a maximum duration of 20mS. Also, there is a delay of approximately 5 to 15mS until the same point is pulsed again. These times depend greatly on the configurations of the other points. ON-OFF-ON Test: Similar activity occurs for this test. The initial time a point is Off is about 5mS. The only fault checked for in this case, however, is that the volts feedback agrees with the commanded state. If it does not, the point is pulsed Off again for about 7.5mS. A maximum of two pulses of approximately 5mS and 7.5mS duration can occur. The 7.5mS pulse occurs only if the volts feedback for the first pulse is incorrect. The T-Block Output Group For level 1/2, GE Intelligent Platforms offered a T-Block Output Group consists of two Genius 16-circuit source-type Genius blocks connected in parallel on one side of a load. The other side of the load is tied to ground. Although the illustration below shows just one load for a group of two blocks, a pair of 16-circuit blocks can control up to 16 loads. Outputs of a T-Block Output Group are “normally-De-energized”. This type of group might be used in high-availability applications where it is necessary to be able to turn ON a critical load. Both blocks must be either 16-circuit or 32-circuit blocks. The two blocks must be connected to two different busses. For a 16-circuit T-Block Output Group, Source Block IC660BRD020 has been used. This block has been designed for use in T-Block Output Groups. It has diodes integrated into the terminal assembly to prevent current feedback from keeping the block powered up, via output connections, when it has otherwise lost power. Output circuits that are to be autotested must be able to withstand the On and Off pulse times used by the test. I-Block Output Group. For level 3/4, the I-Block output has been offered. An I-Block Output Group consists of a source-type Genius block connected to one side of the load and a sink-type Genius block connected to the other side of the load. This type of group is most suitable for redundant shutdown applications. Both blocks in an I-Block Output Group will be 16-circuit blocks. The two blocks must be connected to two different busses. Although the illustration below shows just one load for a group of two blocks, a pair of 16-circuit blocks can control up to 16 loads. An I-Block Output Group might be used in fail-safe applications where it is necessary to be able to turn OFF a critical load. If either block fails, the other can still turn the load OFF. Output circuits that are to be autotested must be able to withstand the On and Off pulse times used by the test. 4.2.5 Genius IO BusEach PLC requires one to three Bus Controllers per redundant GMR bus. Larger systems may require more than one I/O subsystem. Each PLC may have up to 31 Genius Bus Controllers, in multiple racks. What was been represented below, there are 2 sets of triple Genius Buses, 6 Genius controller each has been inserted in CPU rack. It will realize triple separate Analog input and help to meet SIL3.4.2.6 Series 90 TCP/IP RedundancyThe Series 90 TCP/IP Triplex enabler allows HMI to interface to up to three GMR PLCs, with up to 2 network paths per device. With cabling redundancy, the Series 90 TCP/IP Triplex enabler communicates with the PLC using the first path while monitoring the second path. It switches automatically, without PLC intervention, to the second path if the first path fails. It continues to monitor the first path and automatically switches back to the first path on recovery. Cabling redundancy will be implemented with a redundant Ethernet LAN and one connection from each PLC to both of the Ethernet LANs.Proposed system will be redundant CPU, the Series 90 TCP/IP Triplex enabler communicates with one CPU, but automatically switches to another PLC if communications from the first PLC fail. It continues to monitor the PLCs and automatically switches back to a higher-ranking PLC on recovery. 4.2.7 Hardware Detail Information3.2.3.2.1. 3.2.2. 3.2.3. 3.2.4. 3.2.5. 3.2.6. 3.2.7. PLC RacksIC697 racks are considered open equipment, and therefore must be installed within a protective enclosure.· Accepts all IC697 PLC module types · Rear mount racks mount in a 10" (254 mm) deep · enclosure (fans normally not required) · Front mount rack mounts in a standard 19" (480 mm) · rack (fans normally not required) · Accepts plug-in AC or DC IC697 power supply · Provision for two rack operation from single power supply The Standard Nine-Slot Racks and the Five-Slot Rack for the IC697 programmable controller are used for all CPU and I/O configurations. Each rack has provision for one power supply at the leftmost module position; and either nine additional slot locations (nine-slot rack) or five additional slot locations (five-slot rack). Overall rack dimensions are 11.15"H x 19"W x 7.5"D (283mm x 483mm x 190mm) for the Nine-Slot Rack and 11.15"H x 13"W x 7.5"D (283mm x 320mm x 190mm) for the Five-Slot Rack. Slots are 1.6" wide except the power supply slot which is 2.4" wide. Two racks can be interconnected to share a single power supply for applications having extended I/O requirements. A Power Supply Extension Cable kit (IC697CBL700) is available for such applications. Each rack provides slot sensing for rack-type I/O modules designed for the IC697 PLC. No jumpers or DIP switches on the I/O modules are required for module addressing. In this project, we select nine-Slot Racks(IC697CHS790) Power Supply (IC697PWR711)· Operation from 120 VAC, 240 VAC· Three output voltages, 100 watts total ü +5 VDC output up to 18 amps ü +12 VDC output up to 2 amps ü -12 VDC output up to 1 amp · Slide-in rack mount construction · Electronic short circuit overcurrent protection · Two rack operation from a single power supply The 100 Watt Power Supply Module is a rack-mounted unit that plugs directly into a 48-pin backplane mounted connector in the leftmost slot in the rack. It provides +5 volt, +12 volt and -12 volt power, and logic level sequencing signals to the backplane. This power supply may be used either in a single rack application, or may also be used to provide power to a second rack if the total load is within the supply rating. Interconnection to the second rack is through a prewired cable This Power Supply Module can operate from either a 120 volt or 240 volt nominal line (this is jumper selectable, as illustrated on page 3). For these two ranges, the power supply can accept an input voltage range of from 90 to132 VAC or from 180 to 264 VAC, 47 to 63 Hz. The power supply includes an electronic overvoltage protection circuit. This circuit will turn the output off if the 5 volt bus exceeds 6.2 +0.5 V. The power supply must be turned off to be reset. External overvoltage on the output that triggered the overvoltage protection will not cause the power supply fuse to open. However, if an internal fault in the power supply caused the overvoltage condition, the fuse may open. Replace this fuse with a 3AG 3 amp, 250 volt fuse. The power supply provides electronic overcurrent protection for each of the 3 outputs. If the maximum current rating is exceeded, the voltage will collapse to a low value. It will remain in that state until the load is either removed or reduced. A current overload (including a short circuit condition) will not cause the fuse to open. This power supply does not comply with FCC requirements in non-industrial applications for conducted EMI on AC power lines. PLC Controller – CPM790Three models of the Series 90-70 PLC CPU support GMR: CPM 790, CPU 789, and CPU 788. The I/O capacity of the system depends on whether the CPU is a model 788, model 789 or model 790. Considered about to reduce the long-term system operation cost and system consistency, GE Intelligent Platforms proposed CPM790 for both ESD and FGS.The CPM 790 is a single slot programmable controller CPU that allows floating point calculations.

Proper cable selection is critical to successful operation of the system. Conservative wiring practices, as well as national and local codes, required physical separation between control circuits and power distribution or motor power.· Bus Type: Daisy–chained bus cable; single twisted pair plus shield or Twinax. Fiber optics cable and modems can also be used. · Bus Termination 75, 100, 120, or 150 ohm resistor at both ends of electrical bus cable. · Baud Rate: Configurable.153.6 Kbaud standard, 153.6 Kbaud extended, 76.8 Kbaud, or 38.4 Kbaud. · Maximum Bus Length: 7500 feet at 38.4 Kbaud, 4500 feet at 76.8 Kbaud, 3500 feet at 153.6 Kbaud extended, 2000 feet at 153.6 Kbaud, standard. Maximum length at each baud rate also depends on cable type. Greater bus lengths are possible using sections of fiber optics cable with modems. · Maximum Number of Devices: 32 devices at 153.6 Kbaud standard, 153.6 Kbaud extended, or 76.8 Kbaud. 16 devices at 38.4 Kbaud. Includes bus controller and typically a Hand–held Monitor. · Data Encoding: Each bit is encoded into three dipulses, majority voted at the receiver to correct any single dipulse errors. A dipulse is an AC code consisting of a positive then negative excursion of voltage. Dipulses are individually sampled to reject low and high frequency interference. · Modulation Technique:Frequency Shift Keying (FSK) 0 to 460.8 KHz max. (153.6 Kilobaud) · Isolation: 2000 volts Hi–Pot, 1500 volts transient common mode rejection. · Signal/noise Ratio: 60 db The Series 90_–70 PLC Bus Controller (catalog number IC697BEM731) is used to interface a Genius_ I/O serial bus to a Series 90–70 PLC. The Bus Controller handles all data transfer between the PLC and the devices on its bus. In order to do this, the Bus Controller must interface two completely separate and asynchronous activities: · The Genius bus scan, a cycle of communications between the devices on a bus (including the Bus Controller itself). The cycle follows the order of Bus Addresses (0–31). · The CPU sweep, the cycle of actions that includes communications between the CPU and the Bus Controller. The Bus Controller manages data transfer between the bus and the CPU by maintaining two separate on–board RAM memories. One interfaces with the bus and the other interfaces with the CPU. The Bus Controller automatically transfers data between these two memories, making data available to the bus or to the CPU when it is needed. Ethernet Interface (IC697CMM742)· Connects IC697 PLC to an IEEE 802.3 CSMA/CD 10Mbps Ethernet LAN via one of three network ports: 10BaseT, 10Base2, or AUI· 10BaseT and 10Base2 network ports provide direct connection to 10BaseT or 10Base2 network without an external transceiver · Standard 15-pin AUI network port allows choice of 10Base5, 10Base2, 10BaseT, 10BaseF, or 10Broad36 medium with user-supplied 802.3-compatible transceiver · Firmware is pre-loaded for easy installation and is maintained indefinitely; firmware is easily upgraded in-system from PC attached to RS-485 serial port · The Ethernet Interface provides: ü Data exchange using configuration-based and logic-based Ethernet Global Data ü TCP/IP communication services using SRTP ü Full PLC programming and configuration services ü Comprehensive station management and diagnostic tools The IC697CMM742 Ethernet Interface (Type 2) provides high performance TCP/IP communications for the IC697 PLC. The Ethernet Interface (Type 2) plugs into a single slot in an IC697 PLC rack and is configured with the IC641 PLC programming software. Up to four Ethernet Interface (Type 2) modules can be installed in an IC697 PLC CPU rack. The Ethernet Interface (Type 2) contains three network ports: 10BaseT (RJ-45 connector), 10Base2 (BNC connector), and AUI (15-pin D-connector). The Ethernet Interface automatically selects the network port in use. One network port may be used at a time. The 10BaseT network port permits direct connection to a 10BaseT (twisted pair) network hub or repeater without an external transceiver.The 10Base2 network port permits direct connection to a 10Base2 (ThinWire) network without an external transceiver. The AUI network port permits attachment of a user-supplied AUI (Attachment Unit Interface, or transceiver) cable. The AUI cable connects the Ethernet Interface to a user-supplied transceiver that is directly connected to the 10Mbps Ethernet network. The transceiver must be 802.3 compatible and must have the SQE option enabled. Genius IO--16 Circuit DC I/O BlocksGE Intelligent Platforms has offered 16 circuits DC I/O blocks in this proposal.

This flexibility provides maximum design and application efficiency. Each circuit contains built-in protection when used as an output, protecting the driver while allowing short-time surges. It also protects against shorted loads caused by wiring errors. Block LEDs verify proper block operation and CPU communications. Individual circuit LEDs on the logic side indicate voltage present on inputs and outputs VersaMax® Genius® Network Interface UnitThe Genius Network Interface Unit acts as controller for a set of I/O modules. Power for module operation is provided by a power supply that installs directly on the NIUSpecifications:

Module Specifications:
4.2.8 Sequence of events (SOE) recordingSOE (Sequence Of Events) Logging will be accomplished using standard documented library functions on the GMR software CD. The SOE establishes the correct sequence of ten “current” events per user category, time and date stamps these from a possible 128 user assigned events. This table is reset from the user request, or may be automated for operation with SOE station or other device (like DCS or operating console).Additionally, a “historical” log will maintain the last First Out events for the past 10 occurrences. In order to establish a Sequential Order of Events when a trip, request, or shutdown occurs, an application program is available from GE Intelligent Platforms to store the information in the GMR CPUs . The date and time stamps can be read into a SOE station, or DCS asynchronously without concern for losing the sequence information.) The SOE is a library module that is optionally included in the application program to establish Sequential Order of Events functionality. An event can be initiated by system logic, external user request, monitored system error, or any internal application program request. The application program block stores its information in the PLC CPUs. The data and time stamps are logged along with the exact corresponding event, and may be read into a SOE station or DCS asynchronously without concern for losing the sequence information. It could be print out by matrix message printer in sequence or by report printer in customized report forms. 4.2.9 Alarm DisplayGE Intelligent Platforms has offered some sets of Cimplicity PE HMI software. They will be installed on Engineering station/Operator station, used to configure, display and archive system/process/SOE alarm.4.2.10 Time SynchronizationGE Intelligent Platforms GMR will use its integrated function block to receive real-time signal from the system master clock. It may be one of GMR controller or one of engineering station.The system also can get real time signal from DCS or other external master clock through OPC/Ethernet, serial connection or Digital signals. 4.2.11 Serial interface technologyIC200CPUE05 provides two serial ports provide RS-232 and RS-485 interfaces for serial communications and a built-in Ethernet Interface. The RS-232 serial port can be configured for Local Station manager operation to provide access to diagnostic information about the Ethernet interface.The two serial ports are software-configurable for SNP slave or RTU master or slave operation. 4-wire and 2-wire RTU are supported. If a port is being used for RTU, it automatically switches to SNP slave mode if necessary. Port 1 can also be configured for Local Station Manager operation to provide access to diagnostic information about the Ethernet interface. Both ports default to SNP slave and both automatically revert to SNP slave when the CPU is in Stop mode, if configured for Serial I/O. Either port can be software-configured to set up communications between the CPU and various serial devices. An external device can obtain power from Port 2 if it requires 100mA or less at 5VDC. Port 1: is an RS-232 port with a 9-pin female D-sub connector. The pinout of Port 1 allows a simple straight-through cable to connect with a standard AT-style RS-232 port. Port 1 can be configured for either CPU serial communications (SNP, RTU, Serial I/O), or local Station Manager use. If Port 1 has been configured for CPU use, it can be forced to local Station Manager operation using the Restart pushbutton. Once forced, Port 1 remains available for station manager use until the PLC is power cycled, or the Restart pushbutton is pressed. Port 2: is an RS-485 port with a 15-pin female D-sub connector. This can be attached directly to an RS-485 to RS-232 adapter (IC690ACC901). Port 2 can be used for program, configuration. · IO Requirements and Configuration 4.2.12 PCS IO Summary
