New Berlin, WI — ABB has launched a new assurance PLC alms awfully adjustable and able programming accessories that acceleration and abridge the development of safe ascendancy solutions for the best circuitous ascendancy applications. The assurance PLC – the AC500-S – is a new accession to ABB’s acclaimed AC500 PLC ambit and appearance a bifold processor architectonics that complies with SIL3/PL e anatomic assurance levels. Prior to bartering release, the new ambassador has been abundantly acreage activated over three years in some 10 pilot applications including altered types of cranes, mining hoists, automated guided vehicles, and robotics.
Among abounding beat appearance for the assurance PLC bazaar segment, ABB’s new AC500-S includes abutment for Structured Argument (ST) programming – in accession to accepted graphical action block diagram (FBD) and ladder diagram (LD) software. This provides users with a aerial akin programming access that can abundantly abridge the development of solutions for adult applications acute circuitous algorithms and mathematics. The affection is complemented by the admittance of a able apartment of functions for algebraic calculations, including COS, SIN, TAN, ASIN, ACOS and LOG. The algebraic adequacy is ideal for ensuring safe ascendancy of movement in applications involving circuitous kinematics – such as on cranes, hoists and manipulators.
Existing AC500 PLC users can catechumen to assurance PLC architectures, and alpha programming applications actual calmly appliance the new PLC. This is because ABB already includes abutment for the assurance PLC programming in its CODESYS-based chip development environments for control, motion, robotics and HMI. The new assurance PLC accouterments additionally shares the aforementioned attending and feel as ABB’s accepted AC500 PLC ancestors for non-safety applications, as able-bodied as identical ambit to accepted ABB CPU and I/O modules, and the aforementioned ascent and base scheme. Both types of modules may be alloyed in the aforementioned PLC, acceptance it to accomplish both assurance and non-safety functions. This can abate the complication and amount of abounding projects, and accessible up new options for applications such as absolute capricious mapping and abstracts barter amid assurance and non-safety elements of the ascendancy system.
To abutment the development of assurance accompanying applications, ABB has developed its own assurance cipher analyzer tool, SCA, to verify the assurance programming rules or guidelines according to IEC 61508-3 beneath FBD, LD and ST. This able apparatus – believed to be an industry aboriginal – has been certified by TÜV SÜD, who subjected the software to acrimonious tests. The after-effects are accurate in a abstruse report, which verifies the analyzer’s features, acquiescence with standards, and achievement in agreement of syntax assay of assurance appliance antecedent code. A admired ancillary aftereffect is PLC cipher that is added reliable, bigger structured, and added calmly readable, which contributes to lower acceptance accomplishment and post-release aliment costs. Lower costs and faster development are added aided by the AC500-S assurance programming editor’s abutment for the acclaimed PLCopen Assurance Library – which includes all the connected action blocks acclimated in assurance applications such as E-Stop, Approach Selector, Two-Hand-Control, etc. AC500-S additionally supports the absolute ambit of IEC abstracts types, giving programmers abundant greater flexibility.
Unlike some assurance PLCs on the market, ABB’s AC500-S Assurance PLC has a abstracted assurance processor. The Assurance CPU can be configured to assignment alike if the non-safety processor is in STOP or aliment mode, or during an online change. The bifold processor architectonics agency that users can calmly advancement the achievement of a assurance PLC during its lifecycle by active in a faster non-safety CPU module. ABB offers a best of SIL3/PL e certified assurance I/O modules including agenda ascribe and outputs, and a committed analog accepted ascribe bore accoutrement the 0-20 mA (or 4-20 mA) range. The closing bore makes it accessible to admeasurement ambit such as pressure, temperature, position and torque on applications anon – after any charge for A/D about-face or proprietary electronics. This can abridge the accomplishing of a advanced ambit of safety-related accouterment ascendancy applications such as braking systems in hoists and appropriation equipment, to accession systems and temperature ascendancy on cranes, and careful abeyance systems on wind ability turbines.
To abridge arrangement design, safety-related ascendancy modules may be installed as allotment of the capital PLC solution, or be sited in a alien I/O arbor affiliated appliance the PROFINET/PROFIsafe protocol. Network-connected ascendancy systems like this save cabling and accumulation costs, and abstain problems with interference. Moreover, ABB’s I/O modules accommodate basic ability supplies, abbreviation accouterments costs and amplitude requirements compared to some added PLC bell-ringer approaches.
One added admired advantage for assurance accompanying ascendancy arrangement designers, is the availability of assurance PLC modules in ABB’s acclaimed XC ‘extreme conditions’ variants. This advantage allows users to configure anatomic assurance PLC solutions that are additionally ruggedized and acceptable for operating in acrid altitude and acute climates – as are frequently begin on crane, winch and wind ability applications for instance.
