TRICONEX 9853-610卡件說明書
控制器使用EGD數據錯誤的UDP校驗和客戶報告PLC正在使用UDP錯誤的EGD數據校驗和。在以前的版本中，當加速度模式設置為ON（默認）時，未驗證UDP校驗和以減少過載。以太網固件6.20實現了一種方法，允許在以下情況下計算校驗和：加速模式設置為ON，不會影響性能。
控制器在以下情況下沒有響應：配置了TOS/QOS客戶報告，當配置TOS/QOS位時，控制器
沒有響應。
TRICONEX 9853-610卡件說明書固件已更正以繼續當其他設備使用TOS/QOS位時。響應幀將設置TOS/QOS位為0。
SRTP通信問題當多個連接快速打開和關閉時，以太網接口可能進入阻止遠程客戶端使用連接的狀態SRTP通信。這已在以太網固件中得到糾正版本6.20。
以太網限制和開放問題主題描述車站經理“PARM”命令幫助文本錯誤
雖然“parm v”Station Manager命令工作正常，“v”聯機幫助不支持顯示子系統代碼（SRTP服務器）。統計的SRTP請求數可能會有所不同當運行多個SRTP客戶端通道時，報告的請求數由客戶端和服務器決定，連接之間可能有所不同。SRTP連接在IP地址已更改以太網接口不會在之前終止所有打開的SRTP連接更改其IP地址。一旦本地IP地址發生更改，任何現有的打開的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”高級用于將TCP保持活動計時器降低到所需最大值的用戶參數保持斷開連接的時間。參見TCP/IP以太網PACSystems通信，GFK-2224，了解詳細信息。
Controller consumed EGD data with
bad UDP checksum
Customer reported that the PLC is consuming EGD data with bad UDP
checksum. In previous releases, while acceleration mode is set to ON (default),
the UDP checksum was not validated to reduce the overload. Ethernet firmware
6.20 implements a method that allows checksums to be calculated when
acceleration mode is set to ON without impacting performance.
Controller did not respond when
TOS/QOS were configured
Customers reported that when TOS/QOS bits are configured, then the Controller
does not respond. The firmware has been corrected to continue to communicate
when TOS/QOS bits are used by other devices. The response frame will set the
TOS/QOS bit to 0.
SRTP communication issue When multiple connections were opened and closed very quickly, the Ethernet
interface could enter a state that prevented remote clients from connecting using
SRTP communications. This has been corrected in Ethernet firmware
version 6.20.
Ethernet Restrictions and Open Issues
Subject Description
Station Manager “PARM” command
help text is wrong
Although the “parm v” Station Manager command works correctly, the “v”
subsystem code (SRTP server) is not shown as supported by the online help.
Number of SRTP requests tallied
may vary
When running multiple SRTP client channels, the number of requests, as reported
by the client and the server, may differ between the connections.SRTP connections remain open after
IP address changed
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.
