1 Introduction1IntroductionWith multiuser engineering in the TIA Portal you can work with several users jointlyand at the same time on a project.With the parallel editing of different objectswithin a multiuser project,you can considerably shorten the configuration times.1.1OverviewIn TIA Portal as of V14 several server constellations for the functionality ofmultiuser engineering are available to you.This user example describes theparallel editing of projects with a "Temporary Multiuser Server"where the serverfunctionality is realized on one workstation.On the workstation with the multiuserserver,the multiuser server projects are also saved.In order to work with several editors within the framework of multiuser engineeringat the same time,an individual local session has to be created for each editor.Therespective editor can insert their changes in the local session and then check-inand publish these changes in the multiuser server project.After the check-in,thechanges from the local session are again available to all editors in the serverproject.The following figure shows the "Temporary Multiuser Server"server constellation.Figure 1-1:"Temporary Multiuser Server"server

Portal products on the different clients,make sure the samesoftware products of the TIA Portals with identical versions are installed on allthe engineering systems used.NoteTo be able to work with multiuser engineering,a work has to be already setup whilst bearing in mind Windows settings,IP addresses,firewalls etc.The work can also be located within a Windows domainMultiuser Engineering in the TIA PortalEntry ID:109740141,V1.3.06/20182 Engineering2.2Configuration2.2.1Creating user accounts for clients on the multiuser server PGFor the office work described in Figure 2-1 you have to create the user accountsof the clients locally on the multiuser server.The accounts have to be identical tothe accounts of the clients.With this approach the server can authenticate a localaccount with identical login data automatically to an existing server account.Create the accounts on the multiuser server in the system control of Windows.InWindows 7,proceed as follows:1.In the "Control Panel"click on "User accounts>Manage Accounts CreateNew Account"2.Enter the user name of the client,for example,"MultiuserClient1".Select theaccount type,e.g."Standard user"and click on "Create Account"Figure 2-2:Create new accountName the account and choose an account typeStandard userStandard account users can use most software and change system settings that do not affect other users orthe security of the puter.Administrators have plete access to the puter and can make any desired changes.Based onWe remend that you protect every account with a strong password.Why is a standard account remended?Create AccountCancel☐The new account is created.3.Click the newly created account "MultiuserClient1"and then on "Create apassword".4.Enter the password for the "MultiuserClient1"account and confirm thepassword by clicking "Create password".Multiuser Engineering in the TIA PortalEntry ID:109740141,V1.3.06/201872 EngineeringFigure 2-3:Create requestCreate a password for MultiuserClient1's accountMultiuserClient1Standard userpasswords for Web sites or work resources.To avoid losing data in the future,ask MultiuserClientl to make a password reset floppy disk.If the password contains capital letters,they must be typed the same way every time.How to create a strong passwordThe password hint will be visible to everyone who uses this puter.What is a password hint?Create password CancelThe password for the "MultiuserClient1"account is created.5.Repeat steps 1 to 4 for the accounts of the other clients.NoteWhen the server and the clients are member of the same Windows domain,theserver and the clients have to use the same LAN and they have to be created onthe domain controller.If the server and the clients are in the same Windows domain,the account of theclients must not be created on the multiuser server.More information can be found in the TIA Portal V15 Online help or the systemmanual "SIMATIC STEP 7 Basic/Professional V15 and SIMATIC

can be installed together with the TIA Portal.During theinstallation of the TIA Portal,select the "Multiuser server"option.The multiuserserver can also be installed standalone without the TIA Portal.NoteA description for the automated installation can also be found on the productDVD.The tools for the configuration and management of the multiuser server are nowavailable in all languages of the TIA Portal.The multiuser server V14 and V15 can be used side by side.The multiuserserver V15 also supports TIA Portal projects from V14,with correspondingfunctional scope.In order to be able to work in a local session,you need a valid multiuser licensefor each local session.2.2.3Configuring the multiuser serverConfigure the multiuser server with the graphic tool "MultiUser Server V15Configuration".To do this,proceed as follows:1.Open the start menu by clicking the mand "Start All Programs SiemensAutomation TIA Portal Multiuser"2.Click the"Multiuser Server V15 Configuration"entry to open the configurationtool.3.Enter the desired data and click on "Install service".Select how many project versions are to be available as "Rollback"in "Numberof saved
