梯级#3:MOVE WORD函数将零移动到命令块中引用的CRS字(参见梯级#4)。这将清除CRS字。该梯级还重置梯级#5中COMMREQ功能块的OPEN_FLT输出线圈。在启动COMMREQ功能之前,每次清除CRS状态字和COMMREQ故障输出线圈是至关重要的。Rung#4: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Open Modbus/TCP Connection example(开放式Modbus/TTCP连接示例)中定义。Rung#5:COMREQ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。在本例中,前三个数字位(从左到右)为零,不显示;只有后一个数字4出现。这表示机架0,插槽4
Rung # 3: The MOVE WORD function moves a zero to the CRS word referenced in the Command Block (see rung #4). This clears the CRS word. This rung also resets the OPEN_FLT output coil of the COMMREQ Function Block in rung #5. It is vital that the CRS Status Word is cleared and the COMMREQ fault output coil be cleared each time before initiating a COMMREQ function. Rung # 4: 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 Open Modbus/TCP Connection Example in this chapter.Rung # 5: 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. In the example, the first three number places (from left to right) are zeroes and are not displayed; only the last number, 4, appears. This indicates rack 0, slot 4
