太网全局数据命令
当先前传输的命令在网络中经历重试时，在以太网全局数据命令的COMMREQ之后返回0x54A0。再次执行COMMREQ可成功传输命令。Modbus/TCP通道在断电循环期间中止在为运行Modbus/TTCP客户端通道的RX3i通电后，由于服务器拒绝来自客户端的“打开”请求，建立连接偶尔会失败。如果应用程序在看到0x9690或0xAA90对打开请求或第一次写入请求的响应时重试打开，则连接将成功。SRTP流量非常大时以太网异常日志中的控制器响应超时错误（8/08）在SRTP流量特别大的情况下，以太网接口可能会在以太网异常日志（事件08H，条目2=0008H）中记录一个事件，指示过载情况。此错误终止SRTP连接。如果出现此事件，则应减少流量负载，或者应用程序应使用备用通信方法来验证关键数据传输是否因过载而丢失。断电后SRTP信道传输可能需要20秒。当SRTP通信因断电而中断时，以太网接口可能需要20秒钟才能重新建立用于SRTP通信的TCP连接。rmdir Station Manager命令不适用于多级目录路径rmdir Station Manager命令不能在多级目录路径下正常运行。
断电后间歇性
然后在不指定路径的情况下删除目标目录。例如，rmdir dir1/dir2会导致“rmdir失败，dir1/dir2不存在”。相反，首先输入cd dir1，然后输入rmdir dir2。断电后间歇性Ethernet日志事件8H/15H在断电后启动时，Ethernet接口可能会间歇性记录异常（事件08H，条目2=0015H，条目3=0000H，条目4=00aaH）。此异常是良性的，可以忽略。使用killms Station Manager命令时出现间歇性Modbus/TCP服务器日志事件当使用killmsStation Manager指令手动终止活动Modbus/TTCP服务器连接时，以太网异常日志中可能会出现以下Modbus/TTP错误：事件2fH，条目2=0209H、0212H、021bH或0221H。可以忽略这些错误。重置后模块间歇性无响应。当使用按钮或Station Manager命令重新启动模块时，模块将在完成重新启动前闪烁OK LED 5分钟。重启完成后，模块无法与CPU模块通信。补救方法是关闭PLC电源。RX3i以太网接口模块IPI IC695ETM001-JX 2017年11月11日GFK-2332Z限制和开放问题主题描述多次Modbus开放命令尝试后的A890 COMMREQ状态当使用COMMREQ来打开到远程服务器的Modbus/TCP通道时，如果初始COMMREQ返回AA90状态，则未来的开放命令可能返回A890状态。这表明本地网络
Ethernet global data command
When the previously transmitted command is retried in the network, 0x54A0 is returned after the COMMREQ of the Ethernet global data command. Executing COMMREQ again can successfully transmit the command. The Modbus/TCP channel terminates during a power down cycle After powering up the RX3i running the Modbus/TCP client channel, connection establishment occasionally fails because the server rejects the "open" request from the client. If the application retries to open when it sees the response of 0x9690 or 0xAA90 to the open request or the first write request, the connection will succeed. The controller response timeout error (8/08) in the Ethernet exception log when the SRTP traffic is very large. When the SRTP traffic is very large, the Ethernet interface may record an event in the Ethernet exception log (event 08H, entry 2=0008H) to indicate the overload condition. This error terminated the SRTP connection. If this event occurs, the traffic load should be reduced, or the application should use alternate communication methods to verify that critical data transmissions are lost due to overloading. SRTP channel transmission may take 20 seconds after power failure. When SRTP communication is interrupted due to power failure, it may take 20 seconds for the Ethernet interface to re-establish the TCP connection for SRTP communication. The rmdir Station Manager command is not applicable to multi-level directory paths. The rmdir Station Manager command cannot run normally under multi-level directory paths.
Intermittent after power failure
Then delete the target directory without specifying a path. For example, rmdir dir1/dir2 will cause "rmdir fails, dir1/dir2 does not exist". Instead, first enter cd dir1, then enter rmdir dir2. When the intermittent Ethernet log event 8H/15H is started after power failure, the Ethernet interface may record an exception intermittently (event 08H, entry 2=0015H, entry 3=0000H, entry 4=00aaH). This anomaly is benign and can be ignored. Intermittent Modbus/TCP server log events occur when the killms Station Manager command is used. When the killmsStation Manager command is used to manually terminate the active Modbus/TCP server connection, the following Modbus/TTP errors may appear in the Ethernet exception log: event 2fH, entry 2=0209H, 0212H, 021bH, or 0221H. These errors can be ignored. The module is intermittently unresponsive after reset. When the module is restarted using the button or Station Manager command, the module will flash the OK LED for 5 minutes before the restart is complete. After the restart, the module cannot communicate with the CPU module. The remedy is to turn off the PLC power. RX3i Ethernet Interface Module IPI IC695ETM001-JX, November 11, 2017, GFK-2332Z Restrictions and Open Issues topic describes the A890 COMMREQ status after multiple Modbus open command attempts. When using the COMMREQ to open the Modbus/TCP channel to the remote server, if the initial COMMREQ returns the AA90 status, future open commands may return the A890 status. This indicates that the local network
