该输出也可能表明,在以太网接口有时间处理一些未决COMMREQ函数之前,梯形图程序中不能再启动COMMREQ功能。如果设置了FT输出,则CPU没有将命令块传输到以太网接口。在这种情况下,其他状态指示器不会为此COMMREQ更新。以太网接口无法将COMMREQ状态字返回到PLC逻辑应用程序。监视COMMREQ态字每个COMMREQ命令块指令指定一个1字存储器地址,以接收有关命令执行的状态信息。在为以太网接口执行COMMREQ之前,应用程序逻辑应将相关的状态字置零(例如,使用MOVE字指令)。在执行COMMREQ之后,程序应监视其状态字。如果状态字更新为一(1),则表示该命令已成功处理。如果状态字被更新为1以外的值,则表示发生了错误。在问题得到纠正并且状态字指示成功之前,不应使用该命令返回的任何数据。监控每个COMMREQ函数的COMMREQ状态字是至关重要的。
This output also may indicate that no more COMMREQ functions can be initiated in the ladder program until the Ethernet interface has time to process some of the pending COMMREQ functions. If the FT Output is set, the CPU did not transfer the Command Block to the Ethernet interface. In this case, the other status indicators are not updated for this COMMREQ. The Ethernet interface is unable to return a COMMREQ Status Word to the PLC logic application.Monitoring the COMMREQ Status Word Every COMMREQ Command Block instruction specifies a 1-word memory address to receive status information about the execution of the command. Before executing a COMMREQ for the Ethernet interface, the application program logic should the associated status word zero (for example, using a MOVE Word instruction). After executing a COMMREQ, the program should monitor its status word. If the status word is updated to a one (1), the command has been processed successfully. If the status word is updated to a value other than 1, an error has occurred. Any data returned by that command should not be used until the problem is corrected and the status word indicates success. It is critical to monitor the COMMREQ status word for each COMMREQ function.
