www.PLCworld.Parker Hannifin实操派文库What's New实操派文库一最全的For convenience,a"What's New"note at the end of a sectiondescribes any changes from the previous firmware version.Thesechanges are summarized as follows:The existing CIP Status Report mand now reflects that CLASS 1connections no longer use an ACR stream and indicates whichACR parameters are being accessed if a CLASS 1 connection isactive.A new ACR Parameter Class (100)replaces certain legacy servicecodes.See the section Legacy Service Codes on page 27 fordetails.A new ACR Group Class(101)replaces certain legacy servicecodes.See the section Legacy Service Codes on page 27 forde tailsThe current version of the adapter removes the 20-byte binarydata limitation on the legacy Vendor Move mand(servicecode 0x34).and instead,passes the exact CIP Generic messagefunction data directly to the binary mand interpreter.Thisallows the 0x34 service code to be used for any binary mand,including longer binary move mands.实操派文库一最全的工业自动化手册下载到实操派°”，学PLC就是快实操派文库一最全的工业自动化手册下载到-iv-www.PLCworld.Parker Hannifin实操派文库This guide describes how to use a Parker-Hannifin ACR controller in anEtherNet/IPTM(Ether industrial

afundamental understanding of the following:CIP(Control and Information Protocol)object models for devices.CIP object classes for connected and unconnected messaging工业自动化手册下载到EtherNet/IP adaptation of CIPTo install and troubleshoot an ACR controller,a fundamental knowledgeof the following is necessary:Electronic concepts such as voltage,current,and switchesMechanical motion control concepts such as inertia,torque,velocity,distance,and force.www.PLCworld.Parker HannifinOverview of EtherNet/IPEtherNet/IP is the TCP/IP encapsulation of CIP,which is also shared byEtherNet/IP and CIP,refer to the ODVA publication The Specification forEtherNet/IPTM.The following exploration of EtherNet/IP provides contextfor the terms used in this guide.自动化手册下载到A device is a product that supports EtherNet/IP.Some devices conformto industry standard profiles,but there is no such profile for the ACRcontrollers.A connection is a logical link between two devices.Different types ofconnections are described below.Two devices may share more thanone connection.A scanner is a device that initiates a connection or a request.It may bethought of as a master or a controlling device.An adapter is a device that receives a connection request or anindividual service request.Typically one scanner on a work may beconnected to several adapters.An assembly is a pre-defined collection of data residing in an adapter.Each assembly is identified by a unique instance number.Theassemblies are further characterized by their size and type.Three typesof assemblies are producing(data to be sent),consuming(data to bereceived),and configuration(a data area reserved for informationabout how consumed and produced data is to be interpreted).A Class 3 connection is used for individual request/responsethe adapter indicating the success or failure of the request.Theresponse may also include a data payload if it was part of the request.Class 3 connections are handled in EtherNet/IP via TCP.最全的工业A request from a scanner is called a Service Request and the meaningof the request is identified by a one-byte service code inside therequest packet.Most service codes have meanings pre-defined by theCIP specification,but codes 0x4B through 0x63 have meanings that arespecific to the destination object of the service request.The destination of the service request is defined by a portion of theservice request packet called the path.The path is either a literal ASCllcharacter string or an object description.The adapter receiving theservice request can distinguish between an ASCll character string pathand an object description path by header bytes inside the path.A request to an object is identified inside the path by its class numberinstance number,and attribute number.Class identifies which type ofobject is being referenced,and instance defines the particular objectof that type.For example,a carton of eggs contains twelve objects.These objects are instances I through 12 of class Egg.And each objectmay have one or more attributes.In our egg example,attributes I and-2-www.PLCworld.Parker Hannifin实操派文库2 could be size and color.So,a service request might ask for the colorof egg number 6.最全A CLASS 1 connection establishes a periodic exchange of data工业between the scanner and the adapter.The connection request fromthe scanner establishes the repetition interval,or RPI,in both directions.The acronym RPI stands for Requested Packet Interval and is generallyexpressed in milliseconds.This connection request also establishes theinstance numbers of the producing,consuming,and configurationassemblies,and the size of each assembly.It also may contain datadestined for the adapter's configuration assembly,which allows theadapter to interpret subsequent data exchange.In EtherNet/IP,theCLASS I connection is established via TCP,but the subsequent dataexchange uses UDP.A CLASS I connection request also indicates whether the adaptershould send its data point-to-point or multicast.Point-to-point data isaddressed only to the scanner.Mulficast data is sent to a multicastaddress group that includes the scanner.This enables other devices onthe work to receive that adapter's data.If a CLASS 1 connectionrequest indicates multicast,but the adapter does not support multicast,the connection request fails.Individual Class 3 messages may be sent as Connected Messages orUnconnected Messages.These messages are mands or datarequests from the scanner to individual target nodes.ConnectedMessages establish a formal CIP connection between devices,allowingeither device to detect and report the presence or loss of connection.Unconnected Messages result in no periodic Class 3 connection beingestablished.They are managed by the internal stack's UnconnectedMessage Manager(UCMM).实操派文库实AdapterACR Adapter FunctionsThe ACR adapter functions can be divided into two groups,i.e.,Class 3service requests and CLASS 1 connections.Both are intended to allow ascanner access to the ACR P parameters,but in different ways.Thescanner is typically a PLC or HMI software such as Parker-Hannifin'sInteractX.PLCs will usually make both a Class 3 and a CLASS 1动化手册下载到connection.InteractX software makes only a Class 3 connection.TheACR controllers allow only one CLASS I connection at a time,butunlimited Class 3 connections.The ACR adapter plays a passive role in both CLASS 1 and Class 3connections because it simply responds to connection requests andservice requests from the scanner.No ACR mands or parametersare required to allow these connections,but certain ACR mandsand parameters allow an ACR user or program to monitor the statusand description of these connections.-3-www.PLCworld.Parker HannifinA CLASS 1 connection simply sets up a periodic exchange of databetween the ACR P parameters and data tags in the scanner memory.最全的工业The exact configuration of which P parameters,how many,and inconfiguration step,separate from the PLC ladder programming.The Class 3 service requests may result from software driverimplementation,such as Parker-Hannifin's InteractX,or they may bepart of a message box inside a ladder rung of a PLC program.Allservice requests contain a service code and a path.The service codespecifies what is being requested and the path specifies the destinationobject of the request.For some of the service codes supported by ACRproducts,the path may take the form of an ASCll character stringcalled a tag.Others require specification of class,an inst ance,and anattribute.The section Service Codes Using Tags on page 14 contains adiscussion of ACR service codes that accept a tag and ACR objectclasses.ACR CommandsThe CIP status report mand shows the ACR parameters beingaccessed if a CLASS 1 connection is active.Note:CLASS I connections do not use an ACR stream.In the following example,both a Class 3 and a CLASS 1 connection arepresent.The CLASS I connection is producing and consuming every
