产品详细资料
命令块的CPU内存中的地址由COMMREQ功能块的in输入指定。该地址可以是存储器的面向字的区域内的任何有效地址。命令块通常使用Block MOVE或DATA INIT COMM编程指令设置。命令块具有以下结构:数据块长度:这是命令块的数据块部分的字长度。数据块部分从命令块的字7开始。长度是从字7的数据块开始测量的,而不是从命令块开始测量。每个命令的正确值以及每个命令的相关长度将在下一节中指定。(字2)WAIT/NOWAIT标志:对于TCP/IP以太网通信,此标志必须设置为零。COMMREQ状态字:以太网接口更新CRS字以显示命令的成功或失败。命令字3和4指定CRSW字的PLC存储器位置。(字3)COMMREQ状态字内存类型:此字指定CRS字的内存类型。有关更多信息,请参阅本节中的COMMREQ可用内存类型。
The address in CPU memory of the Command Block is specified by the IN input of the COMMREQ Function Block. This address can be any valid address within a word-oriented area of memory. The Command Block is usually set up using either the BLOCK MOVE or the DATA INIT COMM programming instruction. The Command Block has the following structure:Data Block Length: This is the length in words of the Data Block portion of the Command Block. The Data Block portion starts at Word 7 of the Command Block. The length is measured from the beginning of the Data Block at Word 7, not from the beginning of the Command Block. The correct value for each command, and the associated length of each command, is specified in the next section. (Word 2) WAIT/NOWAIT Flag: This flag must be set to zero for TCP/IP Ethernet Communications. COMMREQ Status Word: The Ethernet interface updates the CRS word to show success or failure of the command. Command words 3 and 4 specify the PLC memory location of the CRSW word. (Word 3) COMMREQ Status Word Memory Type: This word specifies the memory type for the CRS word. For more information, refer to COMMREQ Memory Types Available in this section.
