TRICONEX 9853-610卡件说明书
控制器使用EGD数据错误的UDP校验和客户报告PLC正在使用UDP错误的EGD数据校验和。在以前的版本中，当加速度模式设置为ON（默认）时，未验证UDP校验和以减少过载。以太网固件6.20实现了一种方法，允许在以下情况下计算校验和：加速模式设置为ON，不会影响性能。
控制器在以下情况下没有响应：配置了TOS/QOS客户报告，当配置TOS/QOS位时，控制器
没有响应。
TRICONEX 9853-610卡件说明书固件已更正以继续当其他设备使用TOS/QOS位时。响应帧将设置TOS/QOS位为0。
SRTP通信问题当多个连接快速打开和关闭时，以太网接口可能进入阻止远程客户端使用连接的状态SRTP通信。这已在以太网固件中得到纠正版本6.20。
以太网限制和开放问题主题描述车站经理“PARM”命令帮助文本错误
虽然“parm v”Station Manager命令工作正常，“v”联机帮助不支持显示子系统代码（SRTP服务器）。统计的SRTP请求数可能会有所不同当运行多个SRTP客户端通道时，报告的请求数由客户端和服务器决定，连接之间可能有所不同。SRTP连接在IP地址已更改以太网接口不会在之前终止所有打开的SRTP连接更改其IP地址。一旦本地IP地址发生更改，任何现有的打开的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”高级用于将TCP保持活动计时器降低到所需最大值的用户参数保持断开连接的时间。参见TCP/IP以太网PACSystems通信，GFK-2224，了解详细信息。
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.
