Flowserve 6x4-13A自动化控制模块

产品详细资料
通道命令编程通道命令的COMMREQ功能必须通过一次触发启动。这将防止每次CPU扫描都执行COMMREQ，这将超出以太网接口的能力，并可能需要手动重新启动。在启动COMMREQ函数之前检查某些状态位也很重要。特别是，当以太网接口不可操作时，LAN接口OK位应用作联锁，以防止COMMREQ的执行。在通道上启动COMMREQ之后，在从以太网接口向程序返回非零COMMREQ状态字之前，不应向该通道发出进一步的COMMREQ。每个梯形图程序在启动COMMREQ函数之前应执行以下操作。1.用一次触发启动COMMREQ功能。这样可以防止多次发送相同的COMMREQ命令块。2.在LAN接口状态字中至少包括LAN接口OK位，作为COMMREQ功能的联锁触点。
Programming for Channel Commands The COMMREQ function for a Channel command must be initiated by a one-shot. That will prevent the COMMREQ from being executed each CPU scan, which would overrun the capability of the Ethernet interface and possibly require a manual restart. Checking certain status bits before initiating a COMMREQ function is also important. In particular, the LAN interface OK bit should be used as an interlock to prevent execution of the COMMREQ when the Ethernet interface is not operational. After initiating a COMMREQ on a channel, no further COMMREQs should be issued to that channel until a non-zero COMMREQ status word has been returned to the program from the Ethernet interface. Every ladder program should do the following before initiating a COMMREQ function. 1. Initiate the COMMREQ function with a one-shot. This prevents sending the same COMMREQ Command Block more than once. 2. Include at least the LAN interface OK bit in the LAN interface Status Word as an interlock contact for the COMMREQ function.
