Can invent the future of Cheng controller

900 million dollar. "A lot of people think PLC market is stagnant, " HimanshuShah of ARC senior analyst thinks, "However, ARC considers to make clear, although hardware income will ebb, but total PLC market still will maintain growth. " may PLC become daily consumable? Of PLC price reduce ceaselessly, especially the scope that in low end market price case reduces is very big. As the occurrence of the smallest parts of an apparatus, so that the price has 100 only dollar or fewer, these making people goes no longer after attaint repair. Throw away directly however old, change new. But be not cheated by price place. In these " numerous " the power source in parts of an apparatus is notable. Small instruction, even technology of rice of a few accept offers imitate I/O, PID, communication port, till departmental door of spot bus line and company connect quality. Automationdirect company PLC and I/O product manager, paulRuland, notice, "The PLC that 14 I/O nod a 99 dollars contains 4 PID loop and two serial port, can with a 69 dollars 4 passageways imitate inserts card is the choice with a right price suitably, samer than relay a join of odd loop controller be close friends the ground is much. " the PLC support application software with small position of supplier of a few PLC will maintain, can serve as commodity greatly more, this kind of viewpoint is not far-sighted. Siemens the sources of energy and EgonHillermann of manager of automation product market allege, "You can see more hardware. " he explains, you must notice the effectiveness of project tool, diagnose, communication ability and the automation hardware that increase effectiveness the base seal mount. The vice-chairman of SoftPLC, cindyHollenbeck, point out at the same time, "It pays attention to communication and data processing ability more, use them to undertake can more smoothly be operatinged actually. Of I/O linking a network is another remarkable thing. " the answer of the supplier to PLC, PLC of company of motion of Mitsubishi electron automation and relevant software market are in charge of, traytonJay, the proposal pays close attention to a few products that have special property morely. "Cannot be to be on rate merely in a way is a bit quicker. " he is adduce Rockwell serves as an apter example. He alleges Mitsubishi company has acquired next generation terrace, he begins actually at 99 years. Schneider automation also is developing toward this direction, other companies also are doing same business. If PLC is commodity really, you won't see new product appears ceaselessly. Here has a few example to be able to show this one issue. Rockwell added a controller in his CompactLogix series recently. Allen-BradleyCompactLogix5330 (if pursue 1) but along with 1769 compact I/O work, support 16 compact I/O module, and support reachs point of I/O of 256 this locality, the user is available memory is 256Kbyte. CompactLogix uses same Logix to control a tool, use ControlLogix jointly, flexLogix, SoftLogix and kit of RSLogix5000 process designing. Automationdirect company rolls out PLC of miniature of a few KL05. D0-05DD-D is comprised by a DL05CPU, he has 8 Dc input and 6 Dc output, 12/24Vdc power source furnishs, 6K byte memory, RLL/RLLPLUS process designing and RS-23SC process designing and communication port. 6 Dc are outputted, two can configure the CW/CCW pulse that is independence to list output or weak condition and directional pulse output to be as high as 7kHz. D0-05DR-D also is same, 6 output besides it are the means with relay. Siemens uses a new CPU (can have 8 kinds of choices) , patulous series of its SIMATICS7-200 miniature PLC. New CPU, s7-226, increase a dot to be opposite bit of interface (PP) / choose port fully (serial ASCII) , realize industrial LAN or peripheral equipment receive, for example modem, printer, code reader is waited a moment. GEFanuc automation company rolls out new VersaMaxCPUE05CPU. Its characteristic is ability of news report of built-in aether network, faster instruction is carried out time mixes more using to be put in doors. Increased connection of a 10baseT, communication of full duplex operation, through using trade implement go send and accepting data in the meantime, eliminate conflict at the same time, 64K user can configure memory, RS-232 and RS-485 port, the I/O of a this locality, and can choose Genius, ethernet, deviceNet and Profibus industry network. Company of Mitsubishi electric automation has introduced system of new Q series PLC, use the software process designing that is based on window, mere in a lot of circumstances need inspects the item on list, use not lengthy code to develop news report, network, signal processing and other function. An USB port that goes up through CPU types a program. The characteristic support that it has interrelates net E-mail, modem and 10/100base aether net, can receive DeviceNet repeatedly, profibus, CClink and NET/10 network, every CPU is carried out at the same time reach 252 programs, and the appearance is smaller. ControlTechnology company has put in 2601 automatic kit, it includes to increase modular 2601 model controller and Quickstep suit kit of Development of WindowsSE process designing. QuickstepSE is the patent version that CTC is the formulary language of 2601, apply to asking digital control and serial communication are small-sized especially very useful. The program that writes for 2601 can be changed subsequently move in other on controller of 2000 series CTC. IDEC company is new those who roll out is miniature intelligence PLC, in CPU module optional has 10, 16 or 24 I/O. Major attribute includes the circuit of power source supply of a standard, tally of 4 high speed, port of a RS-232 and an imitate potentiometer. I/OCPU module can enhance a function through using auxiliary I/O module at 24 o'clock, i/O dot can amount to 88. The main control of a pair of AS-I that rolls out from Ifmefector company implement, include to be to PLC in IEC1131-3 process designing, carry AS-I and RS-485 news report. AC1011 has an odd controller to contain amount to 124 inputs and 124 output, however AC1012 has two controller and the I/O amount of double. A lot of PLC are used together with operation face plate and other HIM, in a few circumstances PLC function is direct and amalgamative in HMI. Here has two case. The B&RPP21/41 power that rolls out from company of B&R industry automation board, incorporated compact model PLC and system of HMI face plate, become control of compositive low cost machinery and handlers interface. It is had 700-KbyteSRAM and 1.

2-Mbyte shines put, and use IEC1131 language of the standard, ANSIC and process designing of language of B&R automation Basic. EXOR has been passed embed a PLC and I/O arrive a compositive system is patulous face plate of its UniOP series HMI, name for HMIcontrol. PLC module is compatible all UniOP products, contain computer firmware 4.

23 or taller version, and use identical, be based on the setting software package of window, this software package is applicable to all UniOP face plate. The process controls the intense competition in facing traditional market, PLC supplier is fast to the fundamental application that can not write Cheng controller domain or be transferred by the domain of monopoly of a few company. This includes to the process is controlled and be mixed redundantly safe system. Siemens has had a process to control PLC, be in early 90 time initial stage had rolled out SIMATICPCS, put the market on PCS-7 1997 again. As to related to Siemens, egonHillermann alleges, did not differ almost between disperse and process control, because using identical hardware and network two fields are basic and same, mere need adds professional module. "We lade the system is in software. " he says, as shine put, include the software package with stronger sex and faster processor appear, PLC enters a process morely now to treat applied field. Any PLC suppliers try to admit DCS supplier is fluky in themselves domain. Replace, they will be centered on batch processing and disperse control continuously. A good example is Schneider automation company, the QPC that he had rolled out him (process of the quantum theory is controlled) , a system levels this one field cheek by jowl. QPC begins to be controlled at the process, use a distributed PLC that links a network. It is based on QuantumPLC and MomentumI/O platform, and can be on dimensions undertake expanding, to from individual QuantumPLC the center contains the distributed system of Quantum, and distributed Quantums or MomentumI/O system, all these use aether network, interrelate net and TCP/IP technology join are together. Rockwell plans to enhance controller of much discipline of Allen-Bradley adjustment Logix, increase a redundant solution and module of test of a discharge. 1756-CFM can configure flowmeter module to support input of two passageways frequency, frequency limits is 0-120KHz, can accept an input from turbine or large flow flowmeter. Make the process that uses editor of functional board chart and RSLogix5000 controls an instruction 6.

0 version undertake process designing. Control Logix platform also undertakes with RSViewHMI compositive. ActiveX face plate shows with the process control dictates go offerring in ControlLogix show go up in RSView, control application for the process. RS batch processing also provides a capability of compositive S88 batch processing. Toshiba company puts V series on compositive controller, it is amalgamative PLC, DCS and industrial PC pilot are characteristic. Its characteristic includes a mutual project to install a tool to support module of these 3 kinds of platform, bus line of another common motherboard, those who suit ordinal, loop and computational module any incorporating " concentration and mix " , a common uses global variable, WindowsNT4.

The name database of 0, have a common to be based on the LAN of aether net at the same time. Process designing is finish in IEC1131. Web joins the setting that offers long-range project event and breakdown are repaired. To more the demand of systematic dependability increases increasingly. Majority suffers economic atmosphere place to drive, because the cost of workshop shutdown is very big, and debt expenses also rises increasingly. Need implements a large number of standards, be in Europe especially. In some way, situation of use CE standard is same also. Deken alleges, "We know them already very long period of time, subsequently abrupt, you can discover having CE to mark to your product is very main factor. Now, published IEC61508, this is an iceberg merely one horn, be in subsequently 3 or 4 years, will form a big trend. " respect of system of already safe stop work used PLC quite long period of time. The famousest likelihood is Triconex and Pilz, other PLC vendors also are entering this one field actively, it is PLC hardware supplier not just. CindyHollenbeck says, redundant system needs SoftPLC. Confidential and mechanical, the side chooses in hardware special discretion, construct in I/O especially respect. For example, she discovers bus line of a few spots suits, and cannot use however additionally. Other a few well-known PLC companies sortie safety and redundant domain. Rockwell has introduced GuardPLC1200 and controller of 2000 series safety to go monitoring and adjust full automatic the safety that changes a system moves, have at showing PLC photograph is compatible. They have redundant CPU, it is normal to use interior to check circuit to check I/O, and replace use another I/O module before. This product serves appraisal through TÜV product cycle, accord with EC61508, it also is used to support safe grade to achieve the application of 3 class. The ControlLogix platform to it increases Rockwell a redundant choice. New software is 1757-SRM system redundant module and proper choice, when software of use RSLogix5000 process designing, this makes use standard component sets a redundant system together become a possibility, these component include power source supply, motherboard and ControlNet net bridge. Schneider automation company has introduced heat of a Quantum to reserve the choice is critical applying. The processor with its current join, information is returned, go ahead whether does test and verify joins and processor work normally, at the same time the information between processor of long-range I/O of the Quantum that finish is delivered. This heat controls ModbusTCP/IP with processor fully, the address of ModbusPlus and Modbus communication port, because this control is transmitted to client computer newsletter it is transparent. Triconex company releases a few new information that offer money. For smaller application (amount to 450 to nod) roll out modular the new version of redundant controller, major attribute includes an imitate to output module, a pulse inputs module and buildup communication module, increase existing imitate to input additionally, the number is inputted / output, solid state relay outputs module. Additional, it is complete the OPC with new comply with, fit SIL3 requirement through TÜV appraisal, like be the same as DINAK6 class. Introduce its TRICON2003PLC, peculiar one is before version the operation processor of double. In the meantime, as new Trident, TRICON2003 also agreement of comply with OPC. Recently, pilz rolls out PNOZplus, it can amount to 9 inputs to expand unit works together, each contain two inputs, can receive monitor of a text, and but group net, include HCANopen, deviceNet and PLC network. It gets used to EN954-1, category4 standard. Hardware ability includes only channel to receive Category2 repeatedly, be controlled to the double passageway of Category4 or get used to the 3 passageways control of EN201 and EN422. Mitsubishi also has effective redundant unit, his A4ARPLC system had rolled out several years. Siemens the sources of energy and automation motion company also take an active part in the development of this one domain, will roll out its SIMATICS7-400F in September, the completely safe edition of S7-400PLC of a high end, it moves below SIL3 security demand, pass IEC61508 attestation. In a critical incident, the safe state that this controller enters an user to define stops in order for, provide diagnostic data at the same time. The system finishs process designing in environment of SIMATICSTEP7 common development, use to contain the functional program block related to safety library. The Max-ONTM heat that GEFanuc company rolled out it last year reserves redundant software, this software is same PLC of right standard 90-30 series is used, this PLC is OK and mutual communication, realize long-range I/O through a LAN. This software is comprised by Plug-and-play subprogram, these subprograms include variable synchronism, redundant I/O bus line is controlled, program equivalence checks, the choice of lead plane CPU and advanced diagnose.
