Rung#9:BLKMV INT函数设置COMMREQ命令块内容。当这个梯级被激活时,常量操作数从指令中指示的地址开始移动到内存中。本例中的常量操作数在本章的Modbus/TCP读取示例中定义。运行#10:COMMREQ功能块有三个输入参数和一个输出参数。▪ IN字段指向命令块参数的起始位置(本例中为%R00301)。▪ COMMREQ功能块的SYSID字段定义了以太网接口的目标机架和插槽,以接收命令数据。这是一个十六进制字值,用于给出以太网接口模块的机架(高字节)和插槽(低字节)位置。▪ COMMREQ功能块的TASK字段指示指定机架和插槽要使用的邮箱任务ID。对于RX3i ETM001 Jx以太网接口,TASK必须始终设置为零。对于PACSystems CPU嵌入式以太网接口,TASK必须设置为65536(0x10000),以寻址CPU的以太网子板。▪ 如果出现阻止将命令块传送到以太网接口的问题,则FT输出(在本例中为READ_FLT线圈通电)将开启(设置为1)。在这种情况下,其他状态指示器不会为此COMMREQ更新。
Rung # 9: The BLKMV INT functions set up the COMMREQ Command Block contents. When this rung is activated, the constant operands are moved into the memory beginning at the address indicated in the instruction. The constant operands in this example are defined in the Modbus/TCP Read Example in this chapter.Rung # 10: The COMMREQ Function Block has three input parameters and one output parameter. ▪ The IN field points to the starting location of the Command Block parameters (%R00301 in this example). ▪ The SYSID field of the COMMREQ Function Block defines the target rack and slot of the Ethernet interface to receive the command data. This is a hexadecimal word value that gives the rack (high byte) and slot (low byte) location of the Ethernet interface module. ▪ The TASK field of the COMMREQ Function Block indicates which mailbox task ID to use for the specified rack and slot. For the RX3i ETM001-Jx Ethernet interfaces TASK must always be set to zero. For PACSystems CPU embedded Ethernet interface, TASK must be set to 65536 (0x10000) to address the CPU’s Ethernet daughterboard. ▪ The FT output (energizes the READ_FLT coil in this example) is turned ON (set to 1) if there were problems preventing the delivery of the Command Block to the Ethernet interface. In this case, the other status indicators are not updated for this COMMREQ.
