Chapter 4. ConfigurationGFK-2224Q January 2017 57Use of signatures is enabled by default for new RX7i or RX3i projects and is disabled for other targets and forexisting projects.Using Signatures with Run Mode Stores of EGDIf your application will use run mode stores of EGD, the use of signatures is highly recommended. Do not useEGD commands specifying a signature value of 0 because a value of 0 effectively disables the signaturechecking function.For information about the use of signatures with run mode stores of EGD, refer to “Run Mode Store of EGD” inChapter 5.Configuring EGD SignaturesTo select the signature option for a device, right-click the Ethernet Global Data node and choose Properties. TheUse Signatures option is displayed in the properties Inspector window. This parameter may be set to True toenable signature support or to False to disable signature support in the device.Note that both the producer and consumer must have signatures enabled, otherwise signatures are ignoredand only the exchange size is used to determine compatibility.Configuring Ethernet Global Data Using the EGD Configuration ServerThe EGD Configuration Server is supplied with the Machine Edition software, but it is not automatically installedwith Machine Edition. To use the EGD Configuration Server and its associated tools, the server must be installedon the computer as described below.Installing the EGD Configuration ServerTo install the EGD Configuration Server, go to the directory where the machine Edition software is installed andopen the folder named “EGD Installs”. Select the file “EgdCfgServerSetup.msi”. Double-click on the file to installthe EGD Configuration Server.Configuring the EGD Configuration ServerTo configure the Ethernet Global Data server in Machine Edition, click on the Options tab in the Navigatorwindow. In the Machine Edition folder, select the EGD item to display the configuration options for theconfiguration server. For example:Figure 33: Configuring the EGD Configuration ServerLocal Server Cache Path : This parameter sets the path to be used for caching data from the configurationserver. This cache is used if the server becomes inaccessible (for example, if the server is on another machineand that machine is inaccessible due to loss of network communications). You can also choose to work offlinefrom the server and use this cache. This mode of operation is explained below.Base Path : Typically this field should not be changed from the default of /EGD. This is the path portion of theURL used to get to the server.Host Name : The host name for the computer on which the configuration server runs. This can be specified as“localhost” if the server is on the local machine.
