Product line is held in N300 solder electronic-controlled in the system, advocate accuse PLC to use GuardLogix L62S, have can detect the advantage of the short circuit in safe control loop and open circuit breakdown. Safe module uses Safety IO module, safe signal corresponds through the means of safe bus line and PLC, make breakdown more easy search, reduced solder to hold the fault rate of the line thereby, make car solder installs product line to move more safe, stability and reliable. What hold a line in N1 and N200 solder is electronic-controlled in the system, advocate accuse PLC to use RockWell company ControlLogix, safe system uses traditional safe relay, stop urgently, the safety such as grating and safe carpet, through the means of hard wiring series connection arrives one case, form the safe return of whole system. Aborning of this kind of means puts in a few insufficient place: 1. Problem of the short circuit that in dominating return circuit to safety, appears and open circuit cannot detect. When short circuit and open circuit appear in safe return, cannot seasonable indication breakdown, need is versed in to every undertake discharging checking, to maintenance technician the overhaul brings a lot of inconvenience. 2. Use common safe relay (for instance Pilz series) comprise safe return, cannot undertake process designing is controlled, need is built by hand receive safe return, lock of safe each other brings about hardware wiring complex, trival, volume is huge, go against maintenance technician to undertake maintaining. 3. Pass the safe return that hard wiring means comprises, make systematic trouble spot increases, no-go maintenance technician searchs breakdown quickly, increase breakdown to handle time. Hold a line to make up for solder of N1, N200 electronic-controlled the inadequacy in the system, lower systematic fault rate as far as possible, convenient maintenance technician searchs breakdown quickly, resolve trouble quickly, improve the moving efficiency of product line. We hold a line in N300 solder electronic-controlled in systematic design, advocate the GuardLogix L62S that accuses PLC to use RockWell firm, replace traditional ControlLogix; Safe module uses the Safety IO module of RockWell company, replace the safe relay of traditional Pilz series. This design has the following advantages: 1. Can detect the short circuit that appears in safe control loop and open circuit, show trouble in time, need not be versed in to every undertake discharging checking, convenient maintenance technician removes trouble quickly, answer quickly, reduce time stopping a line. 2. Signal of the safety in new plan passes bus line cable to correspond with PLC directly, go besides complex safe hard wiring. 3. Trouble spot decreases, wiring is convenient, reduce maintenance difficulty, facilitating maintenance. Electronic-controlled systematic control framework holds a line in N300 solder electronic-controlled in systematic control framework (see a picture 1) , advocate accuse PLC GuardLogix to be linked together through safe bus line and Safety IO module, safty IO module and labour stop urgently, the safety such as safe grating, safe carpet is linked together directly, every such labour the kind that safety carries safe bus line and PLC correspond. Line of outfit of graph 1N300 solder is electronic-controlled the system controls a framework advocate accuse PLC GuardLogixGuardLogix safety controller is integrated the flexibility of LOGIX platform and high-powered, and the highest grade of the protection that character of compositive and safe control will come to offer an industry to control application in the light of safety (3SIL3 of safe and compositive grade) . Controller module executes standard control and safe control order, a few special safe missions, the safe statement that includes TUV attestation, data, logic and visit protection are used at these functions. Have safe control to all sorts of equipment, can install conveniently inside ControlLogix frame, common module of a power source, I/O, communication and network. All safety, stop urgently for example, the safe grating and safe carpet onefold telecommunication cable that passes use DeviceNetSafetyI/O will control and monitor safe return checks I/O and mistake of factory layout level. Pass double processor framework, it uses advocate safe processor and processor of safety of a conjugate. One of advantage of type of this kind of system are it remains a single item. Conjugate safety processor is one part of the system, automatic configuration, need not the conjugate safety processor that setting, configuration perhaps downloads to need. Debug an environment through convenient development, during safe application development, can many users edit this project, because allow,undertake online editor is mixed compulsive. Accordingly its develop a process to be similar to process of standard application development. Once the project passes a test to prepare to affirm finally, the user should be this secure job setting SIL3 safe level, carry out compulsively by GuardLogix controller next. Safe memory is decided by the lock and be protected, safe logic cannot be revised. Right now, guardLogix operation rises to be like a common Logix. Another crucial time dominant position is, as a result of safety by compositive, safe memory can be read to take by standard logic and peripheral equipment, the safety that does not need to cost time to be appointed from is established or read take safe data. Make thereby inside systematic limits compositive become more easy, and perhaps can choose casing to go up to show safe state conveniently in monitor. GuardLogix uses software of RSLogix5000 process designing, with all Logix but what controller of process designing automation uses is same kind of process designing software, offerred for programmer be familiar with the process designing environment that uses easily. Same RSLogix5000 can undertake administrative to safe memory, the person that use so need not supervise the divisional work of standard and safe memory by hand, also need not use logistic partition alone and keep apart safe data. Nextpage1. Safety of safe and compositive grade is compositive grade namely Safety Integrity Levels, abbreviation SIL. The possibility that produces risk hourly according to the safety that using (PFH) , compositive to safety grade undertakes differentiating. Can differentiate for 4 grade, following watches are shown. 2. Controller of GuardLogix of GuardLogix PLC structure divides composition by two, one is main control implement, model is 1756-L61S or 1756-L62S; Another is safe spouse, model is 1756-LSP. Below the structure of 1oo2, two module are combined, produce a safety, efficient controller, safe and compositive grade achieves SIL3. (1) main control implement ― Primary Controller. Main control implement be opposite with safe spouse all safety in safe return yuan parts of an apparatus is mixed in electrify undertake the function diagnoses a test in moving process. Their condition is shown through LED indicator light come. Main control implement responsible executive standard and function of safe control task and when involving safe function, undertake with safe spouse information is exchanged. It is included advocate the part such as interface of processor, I/O and memory card. Standard function includes: I/O control, logistic, time, computation, forms for reporting statistics, communication, algorithmic computation and data file are handled. Main control implement include two kinds of type, 1756-L61S and 1756-L62S, size of secure job memory is same (for 1M) , but capacity of standard task memory is different, 1756-L61S is 2M, 1756-L61S is 4M. In main control implement on have the select switch that indicates 3 positions, controlling main control implement mode of 3 different operations: RUN -- operation pattern, here mode falls, cannot undertake process designing; PROGRAM -- process designing mode, here mode falls, can undertake process designing, but cannot move; REMOTE -- the program makes can mode, here mode falls, already can process designing, also can move. (2) safe spouse - Safety Partner. To satisfy SIL3 requirement, safe spouse must be installed in proximate main control implement inside the chamfer of right, redundant function is provided for secure job in the system. It did not indicate the select switch of 3 positions and RS232 communication interface, main control implement the operation pattern that has configure and controlling it to its. (3) GuardLogix main control implement process designing tool. GuardLogix main control implement process designing tool is 14 edition or the RSLogix 5000 software of 16 edition. The program below secure job and standard job are same, support echelon to pursue logistic only. Environment of ① process designing. Like the project measure that a project and Controllogix establish is being established in RSLogix5000 software, choose GuardLogix controller, firmware chooses 14 edition or 16 edition. GuardLogix main control implement process designing environment, safety Unlocked increases in controller condition; Safe instruction increases safe share; In director Wu, increase Safety Task; Safety increases safe watermark in editor screen, if pursue,2 are shown. In SafetyTask, mainRoutine arises automatically also. In the red vitta of folder icon lower part, it is to distinguish safe program and standard program come out. Environment of process designing of secure job of graph 2RSLogix 5000 is in MainTask, program Tags, MainRoutine and ControlLogix are same. Nextpage ② secure job. Secure job is periodic task, standard task is successive task. Scanning begins to read in a value, do not change during scanning, safe logic is carried out already froze safe data-in; Secure job is in main control implement with safe spouse in two controller at the same time before, two controller across checks the result of secure job; After scanning ends, keep the outcome to output. ③ Safety Tags and Standard Tags. Standard Tags is used and logistic structure; Standard equipment accuses like HMI, controller and labour machine can read directly take safe label; The safe label of global variable is in average assignment, can be called directly, need not map; Common label is in secure job, cannot be called directly, need has map and the form that uses array. ④ GuardLogix safety dictates. This instruction has 7 kinds, provide 14 kinds of functions. It is ESTOP, DIN, RIN, ROUT, LC, ENPEN and FPMS respectively. Among them, the line is held in solder the most commonly used is ESTOP (stop urgently) with LC (safe grating) . Module of Safety IO of Safety IO module and GuardLogix PLC cooperate to use, through DeviceNet Safety safety bus line has communication. 1. Safety Inputs safety inputs T0, T1, T2 and T3 is pulse test end, output voltage is the test pulse of 24V, t3 end can detect breakdown of peripheral line open circuit. When peripheral line is connected test pulse gives out test signal to detect inside line. Use this function, short-circuit when input and power source end, when end of two power source short-circuits or some input opens circuit, can be detected to come out, data of safe output signal and its condition will be shut. 2. Safety Outputs safety outputs safe output to accompanying pulse to output, when output is ON, test pulse shuts 470ms in every 648ms. Use this function, power source is being carried and output signal for example when output signal between when short circuit, two output short circuit or when some outputs open circuit, can be detected to come out, data of safe output signal and its condition will be shut. 3. The module of DNB of standard of Safety IO module in RSLogix 5000 supports DeviceNet Safety, safe module appears in IO configuration directly, to join, safe, input, output and pulse test end undertakes corresponding configuration, if pursue 3, 4 are shown. The Safety IO in graph 3RSLogix 5000 pursues the GuardLogix PLC of safe bus line of configuration DeviceNet Safety of 4 safe module and Safety IO module pass DeviceNet Safety safe bus line to have communication. Stop urgently, the safe signal such as safe grating, receive Safety IO module directly. Safe bus line is different from common bus line, safe information ensures to after arriving at function and information, undertake iteration corrector a function, ensure the accuracy of data. The first step prep above of safe bus line is common bus line, bring the influence that complete data is not exchanged by the information in common bus line. Epilogue holds a line in N300 solder electronic-controlled in systematic design, advocate accuse PLC to use RockWell company GuardLogix 1756-L62S, partner can network of real time monitoring, detect automatically the open circuit in safe return and short circuit. Once the network is discrepant constant, PLC can stop to move, make the system moves more on the safe side. Safe IO uses 1791DS-IB12 and 1791DS-IB8XOB8, have communication through DeviceNet Safety and PLC, replace the traditional pattern that passes safe relay hard wiring, make installation wiring simple, trouble spot decreases greatly, safeguard convenient.
