KRAUSS MAFFEI 0136.488.01 AK500数字量控制卡
Series 90和PAC系统可能会过早终止。有一个上的TCP“保持活动”计时器值之间不兼容PACSystems以太网接口和Series 90以太网接口。
问题是Series 90模块的设置值比PAC系统。
在Series 90 Ethernet之间保持TCP连接打开接口和PACSystems Ethernet接口，Series 90界面高级用户参数wkal_time应设置为值750以匹配PACSystems的值。通过此更改，TCP连接无限期地保持打开状态。请注意，同一问题发生在具有不频繁通信量且可以用同样的方法解决。
试图打开17个或更多Modbus服务器连接可能会成功如果超过支持的最大16个Modbus服务器尝试连接，TCP连接可能成功，但随后不得传输任何数据Ethernet接口不会终止所有打开的SRTP在更改其IP地址之前连接。一旦本地IP地址已更改，任何现有打开的TCP连接无法正常终止。这会留下SRTP连接打开，直到其底层TCP连接超时。如果更快需要恢复SRTP连接，请修改“wkal_idle”用于减少TCP保持活动计时器关闭的高级用户参数至所需的最大时间，
参见TCP/IP以太网通信PACSystems，GFK-2224，了解详细信息。
用于生成EGD时间戳的CPU时间通过CHTIME命令更改以太网接口时间不影响EGD交换中的时间戳值从此以太网接口生成。EGD时间戳值反映当前CPU时间。在90-70系列产品和Series 90-30 CPU364，EGD时间戳取自以太网接口，并确实反映CHTIME修改。
EGD运行模式存储期间的ENIU陈旧数据在运行20个ENIU的大型PPS系统中，当运行模式存储为删除10个ENIU的EGD交换其他ENIU将看到其交易所的状态显示RMS期间的消耗超时。
在完成RMS，交换机运行正常。使用Internet时，可能需要禁用弹出窗口阻止程序带有RX7i以太网提供的网页的Explorer 8固件。要禁用弹出窗口阻止程序，请在Internet Explorer中工具栏，选择“工具”->“弹出窗口阻止程序”->“关闭弹出窗口阻止器”注意：如果安装了Google工具栏，Google弹出窗口拦截器也可能必须被禁用。
使用时可能还需要禁用配置脚本Internet Explorer 8.在工具栏中选择“Internet选项”。在“Internet选项”对话框单击“连接”选项卡，单击“LAN settings”（LAN设置）按钮，并确保“Automatically”（自动）旁边的框检测设置”中有一个检查。如果没有，请单击旁边的框“自动检测设置”以启用此设置。
An idle Modbus/TCP connection
between a Series 90 and a PACSystems may be prematurely terminated. There is an incompatibility between the TCP "Keep-Alive" timer values on the PACSystems Ethernet Interfaces and Series 90 Ethernet Interfaces. The issue is that the default value of the keep-alive timer for the Series 90 modules is set to a much higher value than for the PACSystems. To keep TCP connections open between a Series 90 Ethernet Interface and a PACSystems Ethernet Interface, the Series 90 Interface Advanced User Parameter wkal_time should be set to the value 750 to match that of the PACSystems. With this change, TCP connections remain open indefinitely. Note that this same issue occurs for SRTP Client Channels that have infrequent traffic and can be resolved by using the same technique. An attempt to open 17 or more Modbus server connections may appear successful If more than the maximum 16 supported Modbus Server Connections are attempted, the TCP connection may succeed, but no data may be subsequently transferred
The Ethernet Interface does
not terminate all open SRTP connections before changing its IP address. Once the local IP address has changed, any existing open TCP connections are unable to normally terminate. This can leave SRTP connections open until their underlying TCP connections time out. If quicker recovery of the SRTP connection is needed, modify the “wkal_idle” Advanced User Parameter to reduce the TCP keep alive timer down to the desired maximum time for holding open the broken connection. Refer to TCP/IP Ethernet Communications for PACSystems, GFK-2224, for details. CPU time used for produced EGD timestamps Changing the Ethernet interface time via the CHTIME command does not affect the timestamp value within EGD exchanges produced from this Ethernet interface. The EGD timestamp value reflects the current CPU time. In Series 90-70 products and the Series 90-30 CPU364, EGD timestamps are taken from the Ethernet interface and do reflect CHTIME modifications. ENIU stale data during Run mode store of EGD In a large PPS system running 20 ENIUs, when a Run-mode Store is performed that deletes the EGD exchanges for 10 of the ENIUs, the other ENIUs will see the status on their exchanges indicate consumption timeouts during the RMS. At the completion of the RMS, the exchanges operate normally.
It may be required to disable
the pop-up blocker when using Internet Explorer 8 with the Web pages supplied with the RX7i Ethernet firmware. To disable the pop-up blocker, in the Internet Explorer toolbar, select Tools->Pop-up Blocker->Turn Off Pop-up Blocker Note: If you have the Google toolbar installed, the Google pop-up blocker may also have to be disabled. It may also be required to disable configuration scripts when using Internet Explorer 8. In the Toolbar select Internet Options. In the Internet Options dialog box click the “Connections” tab, click the “LAN settings” button, and make sure the box beside “Automatically detect settings” has a check in it. If it does not, click the box next to “Automatically detect settings” to enable this setting.
