Seminggu ini pekerjaan saya di dominasi dengan masalah yang ditimbulkan Power Supply di Control Panel ESD System plant. Kebetulan selama disini belum pernah utak atik karena jarang sekali terjadi masalah.
Sistem ESD yang dipakai menggunakan ABB TMR (Triple Modular Redundant) dengan Dual Power Supply Module.
HMI yang dipakai adalah Wonderware Intouch 7.11.
Sistem ini dipasang sudah beberapa tahun dan bahkan ada uang 10 tahun lebih.
Apabila kita lihat di web nya ABB maka TMR Triguard ini sudah tidak ditampilkan lagi. Sudah ada system yang lain.
Tapi sampai saat ini spare part masih di support. Apabila ada permasalahan, masih ada yang membantu memberikan solusi dari ABB Singapore.
Nah sambil utak atik dan belajar, sekalian saya tulis saja di blog untuk disharing….
semoga bermanfaat …
Apa itu ABB TMR?
Berikut info dari pdf produk ini yang didapat dari web ABB.
(searching di google dengan kata kunci “ABB TMR”, dapat lah pdf 3bnp004720r101.pdf_-_en_triguard_2_tmr_safety_products.pdf)

##==> Nah kami memakai di salah satu Plant untuk Sistem Emergency Shutdown & Fire&Gas System. Total ada 4 Control Panel.
P r o d u c t F a m i l y
The ABB Triguard SC300E TMR product family gives unrivalled performance in areas of reliability, availability, test coverage, diagnostics and simplicity of operation.
Advances in technology and improved production methods add cost benefits that give significant price/performance advantages.
• Fewer unscheduled stoppages
highest availability, fault tolerant electronics with transient immunity and 3–2–0 or 3–2–1–0 voting
• Security for plant, product and people
fail-safe operation at all levels provides plant, product and personnel with the highest security
• Quality data
sequence of event and extensive diagnostics keep the operator informed
The Triguard SC300E achieves the highest possible TMR availability (99.999%) by maximising the Mean Time To Failure (MTTF) and decreasing the Mean Time To Repair
(MTTR). Modern low power integrated technology allows the TMR architecture to be cost effective for an increasing range of high integrity applications.
Simple to Use, Operate and Maintain
The Triguard SC300E TMR product functions as a single set of hardware and software. The three processors and triplicated I/O circuitry are transparent to the user. Purchasing a Triguard SC300E system will provide:
• Lowest Life Cycle Cost
• The Maximum Safety and Availability
• The Highest Level of Safety and On-Line Maintenance
Fail Safe Operation
Failure modes of the processors, input/output circuitry, control program and watchdog timer circuits are managed so that circuits will default to a predetermined safe state.
Highest Speed of Response
By using advanced processor technology, whilst maintaining the stability of the original core software, Triguard SC300E delivers an unrivalled scan time resolution of 10ms.
High speed of response benefits the customer application which specifies Sequence of Events recording (SoE) without the cost of additional equipment. It also enables TMR to be used for applications requiring high speed advanced control.
##==> berbeda dengan PLC yang saya ketahui, ternyata saat offline download, setting scan rate ini harus dimasukkan nilainya. Sempat pengalaman tidak bisa offline download dan ternyata step ini ketinggalan. Setelah ambil SOP nya di kantor baru teman kami ingat. Oleh karena itu akhirnya SOP ini harus diletakkan juga di Panel.
##==> Arsitektur dari sistem ini adalah Field input satu buah lalu masuk ke 3 microcontroller masing2 module input. Setelah itu diolah oleh 3 buah processor. Hasil logicnya berupa output di voting 2oo3 (2 out of 3). Kalau satu error, masih ada 2 yang sama maka outputnya dikeluarkan. Kalau 2 error, tentunya hasilnya tidak diterima. Kemungkinan akan ada pesan error. (mungkin lohhh J )
##==> nah yang ini satu chassis utuh.
Yang sebelah kiri atas bawah adalah redundant power supply (module PAC). Jadi kalau mati satu masih bisa di handle oleh satunya lagi.
Pengalaman kemarin satunya intermittent error sampai beberapa jam eh ternyata malah programnya corrupted/error.
Hal ini baru sekali terjadi. Sebelumnya pernah intermittent error langsung cepat ketahuan oleh rekan maint. dan langsung diganti.
Untuk bagian kanan, adalah triple processor / controller. Namanya Module MPP.
Menurut info dari rekan maint. yang sudah terbiasa dengan sistem ini, ketika pertama kali dipakai 3 buah MPP ini harus terpasang baru bisa dioffline download.
Nah kalau sudah jalan, apabila satu MPP rusak maka sistem masih bisa jalan. Ini mungkin hubungan dengan 2oo3 di atas.
Fault Tolerant Hardware and Software
The system is designed to continue to operate correctly with the presence of a major component fault and is capable of tolerating multiple, non concurrent faults.
Easy to Use Software – Windows
TriBuild configuration and application programming and TriCommand Server (WONDERWARE© MMI interface software) are Windows compliant, making the system easier to use for the engineer and the operator. For customers with existing ABB equipment “backward compatibility” is provided making upgrading or adding new facilities economic to implement.
TriBuild and TriCommand Server can be used with Windows NT.
• True multitasking capability
• Strategies can be saved on-line without halting the system operation
• Ability to upload the configuration
• Changes can be made on-line without halting the system operation
• Bumpless changeover of hot repair modules
• Comprehensive diagnostic displays for ease of maintenance
Fault Tolerance and Selective Redundancy
Improvements in the system to keep a process plant running safely without the nuisance of false trips have been achieved by full diagnostic coverage of all modules and selective redundancy. Processors 3–2–1–0 Input/Output Circuits 3–2–1–0 or 3–2–0
Importance of Transient Immunity
Comprehensive physical and electrical isolation combined with asynchronous processors and software voting ensures the Triguard SC300E is immune to transient errors.
Smallest Footprint Size
The Triguard SC300E TMR offers our customers the best utilisation of available space. ABB have developed “plug and play” cabinet layout configurations that offer pre-designed hardware for system applications. Plug and socketed system cables make marshalling and termination interconnection quick and easy to implement.
Product Hardware and Software Description
The ABB Triguard SC300E TMR product has a fully triplicated system architecture from input module to output module. Each system comprises one or more identical chassis housing the power supplies, processors, I/O and communications modules as required by the application.
A single system may be as small as one chassis or as large as 15, giving a maximum of 9,500 I/O. The system is designed to achieve the highest possible reliability, safety and availability and still provide economic advantage. System availabilities in excess of 99.999% can readily be realised, maximising the potential uptime for a customers process plant.
All SC300E input and output modules interface to three isolated I/O communication buses, each being controlled by one of the three processor modules.
Field input signals are filtered and split, via isolating circuits on the input modules, into three identical signal
processing paths. Each path is controlled by a micro-controller to coordinate processing, testing and status reporting to the respective processor. Each processor communicates with
its two neighbours via isolated, read only, high speed links to synchronise input, output and diagnostic status information at least once every scan.
Each processor correlates and corrects its memory image of the current state of the system using a software vote, logging any discrepancies in the diagnostic table. Each processor then executes its programmed application logic and sets its respective outputs to the required state.
Commanded output status from the processors are received by an output module which, using a 2oo3 hardware voter, sets the outputs to the field. Any discrepancy is detected by the
micro-controllers and reported to the processors. All input and output modules can be optionally configured with a hot spare partner module. This allows repairs to be carried out without affecting the operation of the system.
Triguard SC300E Chassis System
There are four basic types of chassis, all using the same mechanics, each providing 10 slot positions for I/O modules and redundant power supplies.
• The Main Chassis
One per system is required and is always complete with two power supply units, three processor modules, the chassis backplane with triple bus systems and plug/socket system module connectors.
• An Extension Chassis
Up to 14 chassis can be connected to a main chassis to suit the capacity master bus extender modules. The master chassis can service up to four remote chassis.
##==> yang kemarin saya lihat di plant adalah 1 main chassis dan 1 extension chassis dipasang di bawahnya.
• A Remote Chassis
Always equipped with two power supply units and three fibre optic slave bus extender modules.
A remote chassis can be sited up to 2km away from a remote master.
Each Triguard SC300E TMR system contains three processors. Each processor operates asynchronously in parallel with the other two processor modules and receives power from the
redundant power supply units in the main chassis. A triplicated bus system on the chassis backplane connects each of the three processors to the I/O and communications modules.
Key features of the processor modules:
• Intel processor
• Battery backed static RAM for application logic –> ada dua battery, lithium 3 VDC
• RAM Battery backup supply for six months
• 1 Mbyte of EPROM
• Real time clock for data logging to 10ms resolution
The Triguard SC300E has an operating system known as the Real Time Task Supervisor (RTTS), which is installed in each of the three processors. The operating system has been proven by
well over 10 million operational hours. RTTS is transparent to the user, it controls the off-line/start-up and on-line continuous diagnostic and voting functions, and provides a single environment for the application programming.
On power up, comprehensive diagnostic routines check and validate the correct operating parameters of each processor.
The Triguard SC300E operating system, RTTS, will permit the processors to operate in a 3–2–1 format allowing a system to continue to function with one healthy processor. A replaced processor will automatically acquire the data it requires to become operational from the on-line processor before going on-line.
All I/O module types share an element of common design, providing component rationalisation and implementing distributed processing. The three isolated TMR signal paths of
all input/output modules are supervised by a micro-controllers which:
• Provides fault isolation
• Co-ordinate signal processing
• Provides diagnostics
• Provides on-line to off-line switching (hot repair)
• Provides data validation routines
• Provides data to the processor
• Provides latent fault detection
A fault in one signal path cannot be passed to another. I/O modules can be fitted in any of the 10 slots in any chassis. “Hot Repair” is a customer configurable option on a per module
basis. All modules are “keyed” to prevent improper installation.
Digital Input Modules
The types of digital input modules available are:
• 32 channel isolated 24Vdc120Vdc120Vac TMR
• 64 channel isolated 24Vdc Simplex
All TMR digital input modules are 100% triplicated to provide maximum availability.
Each signal path conditions signals independently and provides full optical isolation between the field and the SC300E. A fault on one signal path cannot propagate to another.
Automatic latent fault testing will detect “stuck on” states. Line monitored inputs can be implemented using analogue input modules with line monitor termination cards.
Digital Output Modules
The types of digital output modules available are:
• 32 channel – supervised 24Vdc TMR*
• 16 channel – supervised 120Vdc120Vac TMR*
All TMR digital output modules are equipped with:
• Line monitoring circuits to confirm energised field loop integrity
• Six element voting circuits for maximum safety and availability
• Automatic latent fault testing and diagnostics with 100% coverage (TMR)
Each of the three micro-controllers operate two isolated switches per channel which together form a six element voting network.
* Line monitoring of de-energised field loops may be achieved using alternative termination cards.
The output voting, testing, feedback and diagnostics are co-ordinated by the Triguard SC300E operating system. All modules provide 2oo3 voted outputs. Selective redundancy operating in
3–2–1 or 3–2–0 modes is available, with selectable fall back to fail safe or retain last value states.
Analogue Input Modules
The types of analogue input modules available are:
• 32 channel isolated 0 to 5Vdc and 0 to 10Vdc TMR (0 to 40mA and 0/4 to 20mA with burden resistor at the termination card)
Each analogue input signal path contains three identical circuits of:
• Noise Filtering
• Analogue to digital conversion
and each of the three circuits is supervised by a micro-controller.
The three circuits synchronously measure the input signals, vote the data and transmit the data to the processors.
The processors condition the input signal data, making any necessary corrections, and then select the mid-value from the three sets of input data. This mid-value is then used by the control program.
Thermocouple and resistance thermometer inputs are provided by the use of third party transmitters or converters mounted in the field or within the marshalling cabinets. Inputs from these devices are then handled by the standard TMR analogue input modules.
Analogue Output Modules
• 4 channel – 12 bit resolution 4–20mA TMR
Each of the three Triguard SC300E processors sends voted output voltage data to the analogue output modules. The commands are received via the bus system by the three micro-controllers on each module.
Each micro-controller controls a digital to analogue converter which drives two elements of the six element output voting network. Each element of the six element voter is an isolated
field effect transistor operated within its linear range. The final output of the field device is selected as the mid-value from the three circuits of output data.
Feedback to each of the three micro-controllers provides continuous checking for correctness. Diagnostics declare any fault to the processors for maintenance information and action.
Pulse Input Analogue Output
• 8 channel, 4 pulse input, 4 analogue output TMR
The PIANO module contains fully triplicated circuits. Each pulse input path receives input pulses, a value equivalent to the number of teeth on a gear wheel for example, and accumulates this data to an accuracy of +_0.01% over 20Hz to 20KHz. Output values to 12 bit resolution can provide voted and validated data to field devices for control (see analogue output module for output circuit operation).
A four channel serial communications module is always fitted to a Triguard SC300E TMR system to allow communications to the engineering workstation and is installed in I/O slot number 10 of the main chassis.
All four channels operate RS232423 up to 19.2 kbits/sec and all four communication ports are fully isolated.
The four channel communications module is directly addressed by the three Triguard SC300E processors and contains a micro-computer that controls the four programmable multi-protocol ports. Data received from the three processors is voted 2oo3 providing correct data for onward transmission.
##==> komunikasi dari laptop yang terpasang Triguard menggunakan serial port, sehingga dibutuhkan com port. Untuk laptop baru harus menggunakan USB to serial (com).
Selain itu HMI yang dipasang juga menggunakan kabel serial yang dikoneksikan ke salah satu channel port di modul ini.
High speed network connectivity feature (to be released)
Triguard may be interfaced to standard communications networks such as Ethernet/TCP/IP using approved gateway products.
DCS connectivity includes:
• Yokogawa Electric, Elsag-Bailey, Fisher Rosemount, ABB, Honeywell and Foxboro
Hot Repair Facility
A quick repair procedure, once any fault is revealed, is important in the total fault tolerant product strategy.
The hot repair facility achieves a quick and easy repair by the user and this is done bumplessly without interrupting the normal operation of the system and process.
The operating system, RTTS, routinely executes a hot repair task, checking and validating that all configuration data is correct, eg. correct I/O module, on-line/off-line hot repair functions.
All I/O modules can be programmed for a hot repair facility. A wrong or faulty module in an allocated hot repair I/O slot will not be accepted. Hot repair slots are selected to be next to the system I/O resident module.
There are three ways to replace anon-line I/O module:
• Module with no additional hot repair slot – single slot hot repair
• Module has an unpopulated hot repair partner slot – manual hot repair
• Module with a populated hot repair partner slot – hot repair
Field Termination Cards
The types of termination cards available:
• 16 channel – digital input
• 32 channel – digital input
• 16 channel – digital output
• 16 channel – analogue input
• 4 channel – analogue output
• 16 channel – digital output with line monitoring
• 4 channel – pulse input
DIN rail mounted termination cards for field wiring can be supplied as an easy to fit method to route field cables to the Triguard SC300E system I/O modules, and distribute field wetting
current to each I/O point.
A termination card has an associated system cable fitted with DIN connectors to provide the plug and socket arrangement. Cable lengths can be specified to suit the application.
Alternative cables with Elco connectors or free wires at the field end are available for third party marshalling systems.
Power and fusing for the field circuits are standard. Options are available to suit all field configurations.
System cables from the Triguard SC300E are also available with free wire ends so that the system may connect to a separate cable marshalling and power/fusing system.
Optional cabinets to house the Triguard SC300E TMR control system are industry standard 19” rack mounted configurations with a width of 600mm and a depth of 800mm. The
layouts shown are based on a standard 2000mm high cabinets, and provide front and rear access. Front access only configurations are available.
A major benefit of the Triguard SC300E system is that it can be as small as one chassis or as large as 15, giving a 9,500 total I/O capacity. The TMR bus extender modules and cable
sets are used to size the system to suit the application. Interfacing to remote TMR I/O chassis or gateway modules to connect to DCS networks, can be provided to suit a combined distributed safety and control strategy.
A customer who has a future requirement to add to an existing system will find the Triguard SC300E easy and economical to extend.
Forward and backward compatibility means that users can readily intermix CS300 and Triguard SC300E systems using the same programming tools.
Application logic written for a CS300 system will run with minimum modification on the Triguard SC300E.
The Triguard SC300E supports three main application software packages, all are Windows compatible:
• TriBuildfor developing and programming application logic
• TriCommand display and control system workstation (WONDERWARE©)
• TriLog simple PC based alarm/event logger
