KRAUSS MAFFEI 0136.488.01 AK500數字量控制卡
Series 90和PAC系統可能會過早終止。有一個上的TCP“保持活動”計時器值之間不兼容PACSystems以太網接口和Series 90以太網接口。
問題是Series 90模塊的設置值比PAC系統。
在Series 90 Ethernet之間保持TCP連接打開接口和PACSystems Ethernet接口，Series 90界面高級用戶參數wkal_time應設置為值750以匹配PACSystems的值。通過此更改，TCP連接無限期地保持打開狀態。請注意，同一問題發生在具有不頻繁通信量且可以用同樣的方法解決。
試圖打開17個或更多Modbus服務器連接可能會成功如果超過支持的最大16個Modbus服務器嘗試連接，TCP連接可能成功，但隨后不得傳輸任何數據Ethernet接口不會終止所有打開的SRTP在更改其IP地址之前連接。一旦本地IP地址已更改，任何現有打開的TCP連接無法正常終止。這會留下SRTP連接打開，直到其底層TCP連接超時。如果更快需要恢復SRTP連接，請修改“wkal_idle”用于減少TCP保持活動計時器關閉的高級用戶參數至所需的最大時間，
參見TCP/IP以太網通信PACSystems，GFK-2224，了解詳細信息。
用于生成EGD時間戳的CPU時間通過CHTIME命令更改以太網接口時間不影響EGD交換中的時間戳值從此以太網接口生成。EGD時間戳值反映當前CPU時間。在90-70系列產品和Series 90-30 CPU364，EGD時間戳取自以太網接口，并確實反映CHTIME修改。
EGD運行模式存儲期間的ENIU陳舊數據在運行20個ENIU的大型PPS系統中，當運行模式存儲為刪除10個ENIU的EGD交換其他ENIU將看到其交易所的狀態顯示RMS期間的消耗超時。
在完成RMS，交換機運行正常。使用Internet時，可能需要禁用彈出窗口阻止程序帶有RX7i以太網提供的網頁的Explorer 8固件。要禁用彈出窗口阻止程序，請在Internet Explorer中工具欄，選擇“工具”->“彈出窗口阻止程序”->“關閉彈出窗口阻止器”注意：如果安裝了Google工具欄，Google彈出窗口攔截器也可能必須被禁用。
使用時可能還需要禁用配置腳本Internet Explorer 8.在工具欄中選擇“Internet選項”。在“Internet選項”對話框單擊“連接”選項卡，單擊“LAN settings”（LAN設置）按鈕，并確保“Automatically”（自動）旁邊的框檢測設置”中有一個檢查。如果沒有，請單擊旁邊的框“自動檢測設置”以啟用此設置。
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.
