AADvance Safety ManualBPCSBasic process control system. A systemwhich responds to input signals andgenerates output signals causing a processand associated equipment to operate in adesired manner, but which does notperform any safety instrumented functionswith a claimed safety integrity level of 1 orhigher.Refer to IEC 61511 or to ANSI/ISA—84.00.01—2004 Part 1 (IEC 61511-1 Mod)for a formal definition.Equivalent to the Process Control System(PCS) defined by IEC 61508.breakdown voltageThe maximum voltage (AC or DC) that canbe continuously applied between isolatedcircuits without a breakdown occurring.BS EN 54A standard for fire detection and fire alarmsystems.BS EN 60204A standard for the electrical equipment ofmachines, which promotes the safety ofpersons and property, consistency ofcontrol response and ease of maintenance.busA group of conductors which carry relateddata. Typically allocated to address, data andcontrol functions in a microprocessor-basedsystem.bus arbitrationA mechanism for deciding which device hascontrol of a bus.CCIPCommon Industrial Protocol. Acommunications protocol, formally knownas 'CIP over Ethernet/IP', created byRockwell Automation for the Logixcontroller family, and which is alsosupported by the AADvance controller.AADvance controllers use the protocol toexchange data with Logix controllers. Thedata exchange uses a consumer/producermodel.clearanceThe shortest distance in air between twoconductive parts.coding pegA polarization key, fitted to the 9100processor base unit and to each terminationassembly, which ensures only a module ofthe correct type may be fitted in a particularslot. Part number 9903.coilIn IEC 61131-3, a graphical component of aLadder Diagram program, which representsthe assignment of an output variable. InModbus language, a discrete output value.configurationA grouping of all the application softwareand settings for a particular AADvancecontroller. The grouping must have a'target', but for an AADvance controller itcan have only one 'resource'.consumerIn CIP over Ethernet/IP communications, aconsuming controller — a controllerconsuming a tag from another controller.The consuming controller requests the tagfrom the producing controller.contactA graphical component of a Ladder Diagramprogram, which represents the status of aninput variable.continuous modeSee high demand mode.controllerA logic solver; the combination ofapplication execution engine and I/Ohardware.controller systemOne or more controllers, their powersources, communications networks andworkstations.7-2 Document number 553630 Issue 7: February 2010
Chapter 6 Glossary of TermscoverageThe percentage of faults that will bedetected by automated diagnostics. See also'SFF'.creepage distanceThe shortest distance along the surface of aninsulating material between two conductiveparts.cross referenceInformation calculated by the AADvanceWorkbench relating to the dictionary ofvariables and where those variables are usedin a project.Ddata access (DA)An OPC data type that provides real-timedata from AADvance controllers to OPCclients.dictionaryThe set of internal input and outputvariables and defined words used in aprogram.discrepancyA condition that exists if one or more of theelements disagree.DITADigital input termination assembly.DOTADigital output termination assembly.EelementA set of input conditioning, applicationprocessing and output conditioning.energise to tripA safety instrumented function circuit wherethe outputs and devices are de-energizedunder normal operation. Application ofpower activates the field device. Also'energise to action'.EUCEquipment Under Control. The machinery,apparatus or plant used for manufacturing,process, transportation, medical or otheractivities.expansion cable assemblyA flexible interconnection carrying bussignals and power supplies betweenAADvance base units, available in a varietyof lengths. Used in conjunction with a cablesocket assembly (at the left hand side of abase unit) and a cable plug assembly (at theright hand side of a base unit).Ffail operational stateA state in which the fault has been masked.See 'fault tolerant'.fail safeThe capability to go to a pre-determinedsafe state in the event of a specificmalfunction.fault reset buttonThe momentary action push switch locatedon the front panel of the 9110 processormodule.fault toleranceBuilt-in capability of a system to providecontinued correct execution of its assignedfunction in the presence of a limited numberof hardware and software faults.fault tolerantThe capability to accept the effect of a singlearbitrary fault and continue correctoperation.fault warning receiving stationA centre from which the necessarycorrective measures can be initiated.fault warning routing equipmentIntermediate equipment which routes a faultwarning signal from the control andindicating equipment to a fault warningreceiving station.Document number 553630 Issue 7: February 2010 7-3
