在该信道的CRS字为1之前,不要使用从服务器接收的数据。此外,在CRS字被更新之前,不要向信道发起任何附加命令。此规则的例外情况是,当您想使用Close Modbus/TCP Connection命令终止命令时。10.6.6.2监控通道开放位当通道已成功建立与远程服务器的连接时,此位为1,当通道已关闭时,该位为0。当CPU处于运行模式且Modbus/TCP正在使用特定信道时,信道开放位是有意义的。信道开放位在设置的同时,成功状态返回到开放Modbus/TTCP连接COMMREQ的CRS字。10.6.6.3通信请求排序如果以太网接口从CPU接收命令块的速度快于其处理速度,则以太网接口将记录异常事件08,条目2=0024H,并将记录PLC故障表条目:“背板通信与PLC故障;请求丢失”每个通道一次只能挂起一个COMMREQ函数。COMMREQ函数在梯形图程序中启动后一直挂起,直到其CRS字被以太网接口更新为非零值。
Do not use data received from a server until the CRS word for that channel is 1. In addition, do not initiate any additional commands to a channel until the CRS word has been updated. The exception to this rule is when you want to terminate a command by using the Close Modbus/TCP Connection command. 10.6.6.2 Monitoring the Channel Open Bit This bit is 1 when a Channel has successfully established a connection with a remote server, and is 0 when a Channel has been closed. The Channel Open Bit is meaningful when the CPU is in Run mode and the particular channel is being used by Modbus/TCP.The Channel Open Bit is set at the same time the successful status is returned to the CRS word for the Open Modbus/TCP Connection COMMREQ. 10.6.6.3 Sequencing Communications Requests If the Ethernet interface receives Command Blocks from the CPU faster than it can process them, the Ethernet interface will log an exception event 08, Entry 2=0024H and will log the PLC Fault Table entry: “Backplane Communications with PLC Fault; Lost Request” Only one COMMREQ function per channel can be pending at one time. A COMMREQ function is pending from the time it is initiated in the ladder program until its CRS word has been updated to a non-zero value by the Ethernet interface.
