4 • SETTING UP FACTORYTALK DIRECTORY• • • • •For a distributed application, localhost appears beside the Network Directory icon, if thedirectory server is located on the same computer as the application. The host computername appears if the directory server is located on a different computer.Using FactoryTalk Directory in a networked systemYou can set up a network so that multiple RSView SE distributed applications share asingle FactoryTalk Network Directory, or so that multiple Network Directory serversmanage multiple applications.For RSView SE stand-alone applications, the application and the FactoryTalk LocalDirectory must be on the same computer.4 • PlaceholderMultiple distributed applications, one Network Directory computerFactoryTalk Network Directory can contain multiple applications, allowing you to havemultiple automation systems on the same network.This would allow you to develop one application, while another is operating in aproduction environment. Alternatively, different applications can run simultaneously,each controlling a different facility within a corporate network.All the computers participating in a distributed application share a common NetworkDirectory located on a network server computer. Application users can be members ofdifferent domains. If you are not using domains, all of the computers that connect to anapplication must also be in the same Windows ® workgroup.Multiple distributed applications, multiple Network DirectorycomputersA network can also contain more than one computer running the FactoryTalk NetworkDirectory software. This is useful to run multiple distributed applications that:• are separated by a slow network, for example a wide-area network (WAN).To do this, set up one Network Directory at each site on either side of the WAN.• do not need to share data with each other.Each computer on the network can connect to only one computer running the FactoryTalkNetwork Directory software. You cannot connect a single computer to multiple FactoryTalkDirectory servers.4-3
