FLOWSERVE AKH2A 3工控DCS系统

产品详细资料
COMMREQ状态字COMMREQ态字（CRS字）提供有关COMMREQ请求状态的详细信息。通信状态字不会像状态位那样在每次扫描时在CPU中更新。它们通常用于确定COMMREQ功能启动后通信错误的原因。本节稍后将以错误代码的形式报告原因。如果命令块包含语法错误或命令为本地命令，COMMREQ状态字（CRS字）将立即从以太网接口返回到PLC CPU。CRS字的位置在COMMREQ函数的命令块中定义。COMMREQ状态字（CRS字）以如下所示的格式报告状态。CRS字位置在命令块的字3和4中指定。以太网接口将COMMREQ的状态报告回状态位置。有关Modbus/TCP命令CRS字中可能报告的COMMREQ主要和次要错误代码，请参阅2节：诊断。
COMMREQ Status Word The COMMREQ Status word (CRS word) provides detailed information on the status of the COMMREQ request. The communications status word is not updated in the CPU each scan as are the status bits. They are generally used to determine the cause of a communication error after the COMMREQ function is initiated. The cause is reported in the form of an error code described later in this section. The COMMREQ Status word (CRS word) is returned from the Ethernet interface to the PLC CPU immediately if the Command Block contains a syntax error or if the command is local. The location of the CRS word is defined in the Command Block for the COMMREQ function. The COMMREQ Status word (CRS word) reports status in the format shown below. The CRS word location is specified in Words 3 and 4 of the Command Block.The Ethernet interface reports the status of the COMMREQ back to the status location. See Section 12:, Diagnostics, for COMMREQ major and minor error codes that may be reported in the CRS words for Modbus/TCP commands.
