对通道命令使用COMMREQ▪ 确保为每个COMMREQ使用的COMMREQ状态(CRS)内存位置。▪ 在将通道命令COMMREQ初始化到给定通道之前,始终将COMMREQ状态字初始化为零。等待COMMREQ状态字变为非零值(表示COMMREQ完成),然后再向该通道发出另一个通道命令。COMMREQ状态字在每次COMMREQ执行时更新一次:状态字中的非零值完成COMMREQ。▪ 始终使用一次触发来启动通道命令COMMREQ。这样可以防止在每次CPU扫描时执行通道COMMREQ,这将超出以太网接口的能力。▪ COMMREQ状态仅针对每个COMMREQ发出一次;有关详细信息,请参阅▪ 对通道命令使用COMMREQ。在周期错误发生后,挂起的传输仍然可以完成。您可以通过监控通道错误和数据传输位来确定挂起传输何时完成。对于设置为发出多次读取的通道命令,只有在挂起的读取传输完成后才会发出下一次读取传输。
Using COMMREQs for Channel Commands ▪ Be sure to use unique COMMREQ Status (CRS) memory locations for each COMMREQ. ▪ Always initialize the COMMREQ Status Word to zero before initiating a Channel command COMMREQ to a given channel. Wait for the COMMREQ Status Word to go to a non-zero value (which signals the COMMREQ is complete) before issuing another Channel command to that channel. The COMMREQ Status Word is updated once per COMMREQ execution: a non-zero value in the status word completes the COMMREQ. ▪ Always use a one-shot to initiate a Channel command COMMREQ. That prevents the channel COMMREQ from being executed each CPU scan, which would overrun the capability of the Ethernet interface. ▪ The COMMREQ Status is issued only once for each COMMREQ; for more information, refer to ▪ Using COMMREQs for Channel Commands. The pending transfer can still complete after the period error occurs. You can determine when the pending transfer completes by monitoring the Channel Error and Data Transfer bits. For Channel commands set up to issue multiple reads, the next read transfer will be issued only after the pending read transfer completes.
