This means that:• you cannot re-use an HMI server’s name, even after you delete the HMI server.• if multiple users share the same FactoryTalk Directory, the names of all HMI serverscreated by all users must be unique. Similarly, if multiple applications share the sameFactoryTalk Directory, the name of each HMI server in each application must beunique.Number of serversEach area in a distributed application can contain only one HMI server.When deploying a distributed application for production, ensure that there are no morethan 2 HMI servers running on each computer. If the HMI servers are set up forredundancy, only 1 server per computer is permitted.For more information about system limits and requirements, see the RSView SupervisoryEdition Installation Guide.Setting up HMI server propertiesAfter adding an HMI server, you can use the HMI Server Properties dialog box to:• select a startup type for the HMI server.• set up redundancy for the HMI server, and specify the name of the second computerthat will host the redundant HMI server.• select the components that will run when the HMI server starts up.• specify macros that will run when the HMI server shuts down, and, if redundancy hasbeen set up, when the HMI server becomes active or goes into standby mode.• change the name of the computer on which the HMI server is running.5-12
