1. can be used on Microsoft Windows NT and 2000 this version of Server uses corresponding SOHARD ARCNET Raw Drivers included in the installation package Also two different Server Distribution Disks are supplied All further information in this manual is same both for 16 bit and 32 bit versions with the exception of several chapters where NT WinRT and PCI ARCNET card specific items are described The Server is primarily intended for use with Wonderware InTouch version 3 01 and later but it may be used by any Microsoft Windows NT or 2000 program that is capable of acting as a DDE FastDDE or SuiteLink Client What is DDE DDE is a complete communication protocol designed by Microsoft to allow applications in the Windows environment to send receive data and instructions to from each other It implements a client server relationship between two concurrently running applications The server application provides the data and accepts requests from any other application interested in its data Requesting applications are called clients Some applications such as InTouch and Excel can simultaneously be both a client and server To obtain data from another application the client program opens a channel to the server application by specifying three things the server application name the topic name and the specific item name For example in the case of Excel the application name is Excel the topic name is the name of the specific spreadsheet2. Board Name This field is used to enter the ARCNET Board name Board Address This field is used to enter the Board address consistent with the Board Station address selected on the ARCNET adapter card Reply Timeout This field is used to enter the amount of time in milliseconds all Controllers using the selected communication port will be given to reply to commands from the Server Note The default value of 1100 milliseconds should be sufficient for most configurations Board I O Address This field is used to enter the I O base address in hexadecimal of the ARCNET interface The Board I O Address must be consistent with the base address selected on the ARCNET adapter card To select a necessary Board I O Address click on the combo ABB_ARCN DDE Server User Manual Rev 2 5 01010M25 Klinkmann Automation ABB_ARCN DDE Server 9 box button and make your choice from list box Care should be taken to select a base address which will not conflict with other devices in the system Note The default Board I O Address is 2E0 Board Memory Segment This field is used to enter the segment address in hexadecimal for the ARCNET chip buffers The Board Memory Segment address must be consistent with the base memory RAM buffer address selected on the ARCNET adapter card To select a necessary Board Memory Segment click on the combo box button and make your choice from list box Note The default Board Memory Segment address is DOOO When all

Naming and the Server rejects each write to this topic topics If ShowAllRejectedWrites 1 then information about each rejected write value is displayed by the Server If ShowAllRejectedWrites 0 then the Server rejects each write to the suspended topics without logging any information The default values they are used if WIN INI file does not contain these entries are the following WriteRetryCount 0 ConsecArcnErrorsForLog 1 maxPossiblePackages 8 and ShowAllRejectedWrites 1 Troubleshooting menu The following debugging choices are appended to the Server s System Menu the menu that appears when you click the box in the upper left hand corner of the Server window Suspend Protocol Resume Protocol these choices permit you to turn protocol processing on and off what means that you can suspend access to the PLCs ShowEvents if checked then information about suspended and resumed topics are displayed Show Send if checked then outgoing data is logged in hexadecimal format Show Receive if checked then incoming data is logged in hexadecimal format Show Errors if checked then errors are logged ABB_ARCN DDE Server User Manual Rev 2 5 01010M25 Klinkmann Automation ABB_ARCN DDE Server 32 ShowReckPackNumb if checked then number of received ARCNET packages is logged after each request Option is useful only for system configuration not for normal data processing Verbose if checked then all errors are log
4. Notes on Write Command Processing To process more reliable communication a response to write command must be transferred by PLC Application program to the Server after write command is received and successfully processed If the system is configured to process responses to write commands then the Server can recognize whether write command is processed correctly or is it necessary to retry the write command To configure the Server to process response to write command an item WriteRetryCount see chapter Troubleshooting must be included into WIN INI file and non zero value should be assigned to it Value assigned to WriteRetryCount item is number of retries to process write command in case of fault Job Number for Send Package must be used for response to write command and can not be used for response to read commands A response package should contain word value 999 3E7 hex In WW Logger file such response is similar to the following message ABB_ARCN R 02 01 FB 7F 1F 00 E7 03 To create such response package the PLC application program Projekt2 contains the following additional CEs INITV assigning constant value 999 to MW003 15 gt to assign 1 to ASEND enabling bit M003 00 if User First Word in received package indicates data write command gt Z1 gt MW005 00 USER FIRST WORD Z2 MW003 11 const 101 A write Q M003 00 ASEND to store job 31 as data package in storage buffer Write command response data pac

6. Server is going to save the current configuration file The path may be changed if necessary Also the path can optionally be recorded in the WIN INI file by selecting the Make this the default configuration file option Doing so will allow the ABB_ARCN Server to find the configuration file automatically each time it is started Configuration File Location When the ABB_ARCN Server starts up it first attempts to locate its configuration file by first checking the WIN INI file for a path which was previously specified If the path is not present in the WIN INI file the Server will assume that the current working directory is to be used To start the Server from an application directory configuration file other than the default configuration file a special switch d is used For example invoke the File Run command from the File Manager or Program Manager and enter the following ABB_ARCN d c directoryname Note There is no limit to the number of configuration files that may be created although each must be in a separate directory ABB_ARCN DDE Server User Manual Rev 2 5 01010M25 Klinkmann Automation ABB_ARCN DDE Server 11 Topic Definition Command The user provides each Controller with an arbitrary name which is used as the DDE topic for all references to the Controller The following steps are taken to define the Topics Controllers attached to the network 1 Invoke the Topic Definition command The Topic Definition d
