固定IP实际上是远程掩码为255.255.255.255的远程子网的一种特殊情况。但是，您可以为固定IP指定一个固定的信道号，这对于其他类型的远程子网络是无法做到的。指定的频道号不能重叠。请注意，NDPA-02和RUSB-02设备的信道编号始终从零开始连续编号。具有重叠信道号的设备规范在连接时被忽略。OPC服务器DriveWindow 2 7-45还请注意，如果您通过DriveDA OPC服务器进行连接，则所有DriveOPC设备的信道号都会在本地DriveDA信道的最后一个信道号之后移动。该组包含：•IP地址定义IP地址（固定IP）或远程子网的IP地址之一。•远程掩码用于指定组是定义固定IP还是远程子网。对于远程子网，必须提供子网掩码（默认值为255.255.255.255，返回到固定IP）。•通道号可以指定固定IP的固定通道号（在DriveDA OPC服务器的情况下可能会移动）。负值（-1）表示自动编号（Auto）。另请参阅：使用DriveDA配置DDCS/UDP连接到OPC服务器8.配置SAP/http如果安装了DriveDA（不包括在DriveWindow中），DriveWindow 2.40也可以配置DriveDA通信。大多数配置涉及SAP/http协议，但您可以配置DriveDA尝试用于RS-485通信的COM端口的使用。OPC服务器7-46 DriveWindow 2 8.1.1启用NETA-21面板网关NETA-21的出厂设置已禁用NETA-21中的面板网关。为了能够使用SAP/http，必须启用网关。为此，您可以使用web浏览器连接到NETA-21 IP地址。您需要知道用户名和密码才能登录。然后导航到设置->设备界面，选择PNL选项卡并单击设置。将显示界面设置对话框。无论面板网关是否启用，都应启用电缆检查。选择Enable from Ethernet GW，单击Save，最后注销。8.1.2配置SAP/HttpSAP/http配置信息保存在dac_ETH中。ini文件，位于：•Documents and Settings\All Users\Application Data\DriveWare（WinXP）或•Program Data\DriveWare（WinVista/7/8）SAP/http配置对话框实际上实现了一个特殊的ini文件编辑器。OPC服务器驱动窗口2 7-47配置通过从网络菜单的配置子菜单中选择SAP/http来完成。请注意，如果连接到OPC服务器或未安装DriveDA，SAP/http命令将变灰。配置只能在OPC服务器断开连接时进行。此时将打开SAP/http配置对话框，您可以选择要使用的配置。OPC服务器7-48 DriveWindow 2 8.1.3配置您可以有几种现成的配置（例如，针对不同的站点），但当您连接到DriveDA时，只有一种配置在使用中。除了默认配置之外，您可以添加、重命名和删除自己的配置。
Fixed IP is actually a special case of a Remote Subnet with Remote Mask 255.255.255.255. You can specify a fixed Channel Number for a Fixed IP, however, which you cannot do for other kind of Remote Subnets. Channel Numbers specified must not overlap. Note that channel numbers of NDPA-02 and RUSB-02 devices present are always numbered continuously starting from zero. A device specification having an overlapping Channel Number is disregarded at connection time. OPC Server DriveWindow 2 7-45 Note also that if you connect through DriveDA OPC server, the channel numbers of all DriveOPC devices are shifted after the last channel number of the native DriveDA channels. The group contains: • IP Address defines the IP address (Fixed IP) or one of the IP addresses of a Remote Subnet. • Remote Mask is used to specify, whether the group defines a Fixed IP or a Remote Subnet. In case of the Remote Subnet the subnet mask has to be given (default is 255.255.255.255, which falls back to Fixed IP). • Channel Number can specify a fixed channel number (possibly shifted in case of DriveDA OPC server) for a Fixed IP. Negative value (-1) means automatic numbering (Auto). See Also: Configuring DDCS/UDP Connecting to OPC Server Using DriveDA 8. Configuring SAP/http If DriveDA is installed (not included in DriveWindow), DriveWindow 2.40 is able to configure DriveDA communication as well. Most of the configuration concerns the SAP/http protocol, but you can configure the use of COM-ports that DriveDA tries to use for RS-485 communication. OPC Server 7-46 DriveWindow 2 8.1.1 Enabling NETA-21 Panel Gateway Factory settings of NETA-21 have the panel gateway disabled in NETA-21. To be able to use SAP/http, the gateway has to be enabled. To do that you use a web browser to connect to the NETA-21 IP address. You need to know a user name and password to get logged in. Then navigate to Settings -> Device interfaces, select PNL tab and click Settings. Interface settings dialog box is displayed. Cable check should be enabled whether the panel gateway is enabled or not. Select Enable from Ethernet GW, click Save and finally log out. 8.1.2 Configuring SAP/http SAP/http configuration information is kept in dac_ETH.ini file, which resides in: • Documents and Settings\All Users\Application Data\DriveWare (WinXP), or • Program Data\DriveWare (WinVista/7/8) The SAP/http Configuration dialog boxes actually implement a special INI-file editor. OPC Server DriveWindow 2 7-47 Configuring is done by selecting SAP/http from the Configuration submenu of the Network menu. Note that the SAP/http command is grayed if you are connected to an OPC Server or if you do not have DriveDA installed. Configuring can only be done while OPC Server is disconnected. The SAP/http Configuration dialog box is opened and you can choose the configuration to work with. OPC Server 7-48 DriveWindow 2 8.1.3 Configurations You can have several readymade configurations (for different sites, for example), but only one of them is in use when you connect to DriveDA. With the exception of the Default configuration, you can add, rename, and delete configurations of your own.
